Security Techniques
CCN
COMPUTER resources have worked with multiple techniques for transaction security
and fraud control. Some of these are:
|
|
|
- Encryption key
exchange process
|
- Interface to
security devices
|
|
|
- Message
Authentication Codes (MAC)
|
|
|
- EMV upgrades to
support VSDC and other products

Accesses
to all GUI screens of system are password protected. Only users with suitable
authentication and authorization can accesses system screens. All user-performed
changes are fully logged for the purpose of establishing an audit trail. Along
with the details of the changes performed by the user, the date, time and
user-id are also recorded.
Our
resources have also developed interfaces to physically secure devices. These
devices are used for all system encryption and decryption tasks such as:
PIN
block translation
PIN
creation
Message
authentication
Key
exchange and generation
PIN
mailer production
HSMs
can be connected to the system using the TCP/IP communication protocol.
Asynchronous protocol can be used with the HSM. Multiple HSMs can also be used
to improve transaction throughput.
