ACOS2 is specifically designed for highly secure applications. With this high degree of security feature, ACOS2 is particularly suitable for Dekart applications such as Dekart access control software,file and disk encryption software and multitude of other applications in which security is extremely critical.
One smart card can be used to store passwords and encryption keys required to access different Dekart and non-Dekart applications, reducing the costs on multiple devices.
ACOS2 security features
Digital Encryption Standard (DES) This mode of protection
uses ciphering, which is analogous to the translation of stored
information into some unknown foreign language so that it can be
transmitted confidentially. Simple DES or Triple DES versions are both
available.
Message Authentication Capability (MAC) – This
is based on the exchange and mutual verification of secret passwords
[keys] between the card and the card-accepting device. The whole
verification process is processed within the device, and information is
never transmitted outside during the process, making eavesdropping
virtually impossible.
Enforced Message Authentication with random numbers and dedicated key pair.
Continuous system integrity checks, to guard against attempted security breaches.
Five
secret codes + Issuer Code + Pin, to selectively enable access to data
stored in card and to features and functions provided by the card e.g.
the READ and WRITE commands.
Account Transaction Processing
(ATP), provides dedicated data structure for payment applications with
CREDIT, DEBIT, INQUIRE ACCOUNT commands for secure transaction
processing.
Other features
Compliant with ISO 7816-1/2/3, T=0
Issuer can define the file structure for convenient and efficient memory management
Single DES or triple DES for encryption algorithm are available
