1. Introduction to Secuway PCI
As a key component of the SecuwaySuite, SecuwayPCI operates in conjunction with
SecuwayCenter and SecuwayGate and provides the comprehensive solutions related to the security
items of data transmission.
SecuwayPCI is a hardware-based security token that encrypts and decrypts network packets
through key management based on Internet standard.
SecuwayPCI saves the communication key on PCI security board after receiving it from
SecuwayCenter administrator. As the security functions are from the SecuwayPCI security board,
they will be activated on installing the SecuwayPCI security board, saving users from making
separate preparation to activate them. PCI board provides fast data transmission through many
different computing environments, regardless of its being ATM or desktop.

2. Features of Secuway PCI
SecuwayPCI features:
Security token in PCI board type
The PCI board-typed security token is easy to install, fast and provides the straightforward
interface.
Compliance with the security standard
SecuwayPCI is in full compliance with the international standards including IPSec (Internet
Protocol Security Protocol), IKE (Internet Key Exchange), and Cryptoki (PKCS#11). It is ready to
work with other upcoming products.
Providing data communications security
In line with IPSec, SecuwayPCI provides the authentication mechanism (AH: Authentication
Header) that authorizes the producers of packets and verifies packets. SecuwayPCI performs
Encapsulating Security Payload (ESP) that encrypts the data entailed in packets to meet the
communication security requirements. SecuwayPCI uses the standard TCP/IP protocol allowing
users to send encrypted data to destination in the network.
Korean-government certified encryption algorithms
SecuwayPCI uses the encryption chips and hardware developed under the Korean government’s
supervision. As a security device, SecuwayPCI performs reliable encryption and decryption process.
Automatic upgrade
SecuwayPCI automatically reflects the changes made on relevant files.
Records the action history
SecuwayPCI manages and records the users’ information and their actions that can be printed out
and saved on disks. Administrators can use this function to keep track of users and find a root-cause
of errors and security breaches.

3. System Security
To meet the system security requirements, SecuwayPCI selects or removes a folder related to
hard disk encryption/decryption as well as settings of floppy disk security functions.
* This function is not available with SecuwayPCI for ATM operations.
* Regular users cannot use the system security functions.
System security functions allows you to perform following:
When a file is copied to a folder on the security path, SecuwayPCI encrypts the file.
When a file on the security path is copied to a folder out of the path, SecuwayPCI decrypts the
file.
SecuwayPCI allows the access to files on the security path only to those uswrs, which are
registered with the SecuwayPCI program.
If a disk is protected through the SecuwayPCI disk security option, files on the disk cannot be
opened in other systems without SecuwayPCI program. If a user copies a file from a
SecuwayPCI-protected hard disk to other system without SecuwayPCI program, the content
of files cannot be read because it is encrypted.
Sub folders of a folder on the security path are protected by the same security functions.
When a folder is put on the security path, the existing files in the folder will be all encrypted.

1. Adding a Security Path
Once a folder is added on the security path, the files and the programs in the folder are
automatically encrypted and decrypted when they are copied or activated. This function does not
allow unauthorized users to get access to users’ system.
Once a folder is included in a security path, copying files is allowed, however moving files to
a directory outside the security path is disabled. Moving a file causes errors.

Files on a floppy disk will not be encrypted in regular disk mode. The right side window of the
system will have an icon looking like a floppy disk.
This is when a user decides to use a floppy disk without encryption.
Security disks
All the information on a floppy disk is encrypted and saved in security disk mode. Information on
the disks goes through decryption, when a user brings up the information.
Security disk mode is indicated by the icon of a disk with a key.

1. Registration Information
IPSEC displays the information on SecuwayPCI security token issued from a SecuwayCenter.
IPSec registration information
The registration information comprises the settings of SecuwayPCI active in the networks.
$
Main SecuwayCenter IP address, Redundant SecuwayCenter IP address
A main SecuwayCenter IP address, redundant SecuwayCenter IP address, and authentication
port are from SecuwayCenter. Enter an altered IP address, should system settings or network
environment be modified.

User definition subnet mask is a subnet mask according to user IP address. Standard subnet mask
in A, B, and C classes doesn’t require user definition subnet mask. A Class is 255.0.0.0, B Class is
255.255.0.0, and C Class is 255.255.255.0.
Should subnet mask IP not be in the standard A, B, and C, tick on the user definition subnet mask
and enter a subnet mask. For example: if IP address is 100.100.100.1 (A class) and subnet is
255.255.255.0 (C class), click the user definition subnet mask and enter the subnet.
$
Master Key
A master key is used for encryption and keys in use are listed up from the total 100 keys.
SecuwayCenter determines the value of keys and sends it to SecuwayPCI. The key values must be
the same in different devices in order to ensure the communications take place.
If a user changes the master key value ignoring the instruction of SecuwayCenter administrator, the
encryption will be disabled. Thus, it is important to remind users avoid to alter the master key value
of their own.

Host
Hosts are IPSec objects. Hosts include SecuwayGate, dynamic IP address, and static IP address.
SecuwayPCI is an object either with dynamic or static IP addresses by light of IPSec.
Host ID
Host ID is the only identifier for each IPSec host registered with SecuwayCenter. Host ID
consists of 8 bytes (the first 4 bytes are currently pre-determined) in
이진값
and screen pointer?
goes in the order of a-bbb-ccc.
All the SecuwaySuite products follow the same numbering system for all host IDs. The first digit
is the type IPSec hosts (devices): 0 is SecuwayCenter, 2 is SecuwayClient, SecuwayPCI and
SecuwayGate.

Master Key
Master key is the highest security key of all in the IPSec standard and each IPSec host has the
unique value.
2. Key token information
Key token is a shared key among IPSec hosts for security communication.
Key token ID
Key token ID is the only identifier to tell apart key tokens. Key token information is created when
an IPSec host starts communicating with other host, as shown above. SecuwayCenter sends key
tokens to help encryption process.
There is no communication with SecuwayCenter or an error is caused by network settings, if no
key token is created between the hosts attempting to communicate. Check the SecuwayCenter IP
address and that of a computer with SecuwayPCI to ensure that they are appropriately entered to
the system.

Remote Host ID
A remote host ID is for users who gain access into the system through SecuwayPCI.
Valid starting date
Valid starting date is used when hosts start communicating with creating a key token.
Key tokens and SA are created when IPSec hosts perform the encrypted communications.
3. SA Information
SA (Security Association) is shared encryption, authentication mechanism, and keys between
two hosts necessary to protect the exchanged information. SA information varies depending on the
security protocol.
SA window displays both sender’s and recipient’s SA information, remote host ID, and IP
address when communication takes place normally.
See below for an example of SA information displayed during encrypted communication. The
upper part displays key token ID of a host being accessed, while the lower part shows remote host
ID, its IP address, authentication/encryption algorithms in use.

Sender, receiver, and SA information is created to provide the connection status to a
corresponding host.
If two hosts are in different security mode, request from a host trying to have access is not
returned with response. Set the same security mode profiles for two hosts.
4. Managing Security Policy
Security policy is database of rules of how IPSec standard should process IP packets. Security
policy is composed of sub rules that work on packets in ascending order, meaning Number 1 rule is
the first rule to be applied.
4.1 Formation of Security Policy
Security policy is divided into higher, lower, and user defined policy. SecuwayPCI administrator
creates user-defined policy. SecuwayCenter determines the priority of the policy.
Security policy is presented as
!
for higher policy
"
for user policy
#
for lower policy.

Writing a security policy
Make sure to save the changes by pressing the “Write a security policy” button after adding or
deleting a rule in user policy setup menu. The security policy takes effect after saving.
The “write a security policy” button is located on the user policy setup tab. Only SecuwayCenter
can determine the priority of security policy (higher, lower); even the SecuwayPCI administrator
cannot do the modification.
Viewing the latest information
Higher policy
Press

Lower policy
Press the lower policy tab menu
#
to bring up the list of lower policy. Only SecuwayCenter
administrator can determine the priority of policy and SecuwayPCI administrator cannot modify or
delete it. The lower policy allows the network environment to operate and saves SecuwayPCI
administrator from manual setup processing. The maximum number of lower policies is 10.
Security policy works in order of higher, user definition, and lower policy. If two different rules
have conflicting details, SecuwayPCI program applies a higher rule over lower rule.
Operating security policy
Once SecuwayCenter sets up a policy that allows all the hosts to communicate, except the servers
protected by security function, SecuwayPCI administrator doesn’t have to create settings for
communications. That is to say, SecuwayCenter writes all the rules to ensure SecuwayPCI works
on networks without the necessity to write new rules.

1. What is IPSec?
SecuwayPCI is based on the IPSec standard that manages security keys using IKE protocol. The
IPSec standard and IKE protocol are:
1.1 IPSec Standard
IPSec (Internet Protocol Security Protocol) is Internet security standard that makes up for
downsides of TCP/IP protocols and standardizes the IP protocol-based security services. The IPSec
standard is documented in RFC 1828-1829, 2104, 2085, 2401-2412 and 2451 of IETF (Internet
Engineering Task Force). SecuwayPCI is fully compliant with the requirements.
1.2 Features of IPSec
IPSec is highly flexible protocol designed to materialize multiple security services required of
different Internet environments. IPSec is designed to accommodate the security requirements that
arise with the development of Interent. IPSec has the following features :
"
IPSec is an effective solution that addresses the shortfalls of TCP/IP communications and sets up
the reliable paths for encrypted communications between hosts.
"
The autonomous IP security protocol and key management mechanism ensures that IPSec is
flexible to adapt to varied Internet environments.
"
IP security protocol is divided into authentication (AH) and encryption (ESP), allowing users to
select the security service suitable for their computing environment.
"
It is easy to add a new security mode to security protocol. Various encryption and authentication
algorithms are available.

1.3 Formation of IPSec
IPSec is broken down into IP security protocol and key management protocol. IP security
standard and key management protocol work independently, but are still connected through SA
(Security Association).

SA(Security Association)
IP security standard consists of:
A) AH: Authentication Header that verifies the origin of IP packets and authenticity of packets
and
B) ESP: Encapsulating Security Payload that provides the confidentiality of data transmission.
Users can selectively choose from two mechanisms to their system requirements or choose
both of them.
1.3.1 SA (Security Association)
SA is the logical settings for security mechanism, security mode, authentication, and encryption
algorithms, key values, and other parameters. SA goes only in one direction requiring senders and
receivers to set up and maintain their own versions. Set by key management protocol, SA is used to
provide the security to IP protocol. SAs can be told apart by IP address and 32-byte SPI (Security

1.3.2 Authentication mechanism
Authentication mechanism (AH) provides the connectionless integrity, data origin authentication,
and anti-replay service.
An authentication mechanism measures MAC value of IP packets of a sending host and transfers
the packets. For incoming hosts, AH measures the MAC value of them to see if it is the same as
received value. Authentication key reads only two communicating hosts, eliminating the possibility
of a third party copying IP packet and authentication information. AH tells apart authentic IP
packets of a communicating host from unauthorized copies. Packet sequential number of 32-byte in
AH is used to measure MAC (authentication information) preventing replay attacks that take
advantage of the transferred IP packets.
With AH in use, the number “51” is placed on the next header field of IP header in front of AH,
meaning that next AH comes up.

1.3.3 Encryption mechanism
Encryption mechanism (ESP) provides the IP packet data confidentiality and selectively includes
the authentication information in order to support connectionless integrity, data origin authentication,
and anti-replay service.
The encryption mechanism encrypts IP data (higher-level data) excluding the header to ensure
![](/img.php?id=167015&img=bg43.png)
Appendix
65

65
the confidentiality of communications. It measures the MAC value on ESP header and IP data to
provide the encryption services. AH calculates all the authentication information related to IP
packets, while the ESP factors in only the ESP components excluding the authentication
information field.
When the ESP in place, the next header in the IP header has the number “50” for the field value
to indicate that ESP is in use. The general formation of ESP is:

1.3.4 IKE Protocol
IKE protocol is a key management protocol that authorizes the hosts for IPSec communications
and negotiates with SA to determine the process and formula of setting up, modifying, and deleting
security keys.
IKE protocol manages the keys through two steps . In step 1 two hosts that are up for
communications authorize each other and set up their own ISAKMP SA. In step 2 the IPSec SA
comes into play for IPSec communications like AH and ESP. The ISAKMP SA formed in step1
protects the messages created in step 2. Each step sees negotiation, formation, key exchanges, and
mutual authentication going on in preparation for SA information to be used later.

2. Definitions of Terminologies
AH (Authentication Header)
AH is an IPSec protocol that provides powerful connectionless integrity and data origin
authentication to IP packets. It supports anti-replay service as an option to users.
ESP (Encapsulating Security Payload)
ESP is an IPSec protocol that guarantees the confidentiality of IP packets. On top of this, it
provides connectionless integrity, data origin authentication, anti-replay service, and limited traffic
flow confidentiality services.
Ethernet
Ethernet is LAN-based communication developed by private companies, such as: Xerox, Digital
Equipment (DEC), and Intel. IEEE802.3 is the second version of Ethernet standard developed on
the base of IEEE802.3 designation. Thus, Ethernet version 2 and IEEE802.3 can operate on one
cable while Ethernet version 1 and 2 don’t co-exist.
HOST
Hosts are nodes that are connected to network.
IPSec (Internet Protocol Security Protocol)
Developed by IPSEC Working Group, IPSec is standard Internet security protocol that
overcomes the shortfalls of TCP/IP protocols in network and standardizes security mechanisms. It
is designed to service the current IPv4 version as well as IPv6—the next generation Internet
protocol. IPSec standard defines security protocols (AH, ESP) for network communications, SA,
and key management protocols (IKE).
IPSec security mode
IPSec security mode refers to all security services activated on an IP packet. AH and ESP are
applied to a packet: one in transport and the other in tunnel mode or all in transport mode
simultaneously.

IPSec security profile
IPSec security profile is comprised of multiple security modes listed up in order of priority. The
security profiles are used to negotiate with a corresponding IPSec host over IPSec SA in step 2 of
IKE protocol.
SA
SA (Security Association) is a series of mechanisms and keys shared between hosts to protect
communication information. The definition of communication information varies depending on
security protocols.
SecuwayGate
SecuwayGate is hardware-typed security device that protects TCP/IP communications between
network server interface and users or between multi-layered network interface and multiple users.
Security Rule
Security rules are the basic components of security policy. Security rules are comprised of the
packets, security decision, and security mode for IPSec communication. Should a packet be eligible
for security policy, the security rules allow, reject communication or pass for IPSec
communications.
Making a decision
Decision is made on how to process a packet. The types of decisions are: “Allow the
communications”, “Disable the communication”, and “IPSec communication” that uses key
management.
Master key
Master key is the highest level of keys in IPSec security function. It has unique value to each
IPSec host. SecuwayCenter determines the master keys.
Security policy
Security policy is a type of database that contains the rules on how to process IP packets in IPSec
communications. Security policy is a list of rules that goes down in order of priority. Rules refer to
![](/img.php?id=167015&img=bg47.png)
Appendix

the internal information to decide whether to work on a packet or not. This reference check-up
process goes on until a packet is matched with a right rule that will examine the packet. When no
rule is found for a packet, the packet is discarded and the communications are interrupted. Security
policy implemented in IPSec hosts, such as: SecuwayClient, SecuwayPCI, and SecuwayGate is
divided into higher-level, lower-level, and user defined policy, according to a creator of the policy
(either SecuwayCenter or host users). The security policy takes effect in above-mentioned order.
The higher and lower-level policy are made in SecuwayCenter and delivered to IPSec hosts, while
IPSec hosts draft user define policy.
Security token
Security token is software modules and hardware (SecuwayPCI) that provides log-on,
encryption/decryption, measures/confirms authentication information, and manages time services
(this is optional by products) for network communication security services. Security token is fully
compliant with Cryptoki (PKCS#11) standard API by RSA.
User defined policy
This is a security policy made by IPSec hosts. User defined policy comes after higher and before
lower-level security policies in order of priority.
Higher-level policy
Made by SecuwayCenter, higher-level policy has the highest priority among security policies.
Higher-level policy is rules that must be implemented to IPSec hosts.
Lower-level policy
The lower-level policy takes the back seat to higher-level and user defined security. Made by
SecuwayCenter, the lower-level policy governs on how to process a packet that is out of the scope
of definition by IPSec users.
Communication allowed
“Communication allowed” is a decision that rules out IPSec security on handing an IP packet.
This allows to income the IP packet as it is, without encryption.
