ACOS2 smart card

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
