BIO-Tag AT88SC0104C Smart Card

Description

Features
Security

The device includes a random generator and a proprietary algorithm similar to DES for encrypting data, passwords and providing MAC for read and write operations, thus providing data integrity and certification of data origin. Each device is differentiated from all others after personalization through a unique identification number and set of secret keys. The device secret keys are issued from the application secret keys using an encryption algorithm such as DES, 3DES, AES, etc., which is chosen by the issuer. This function is performed outside of the device.

This is the only Secure Memory family of devices in the industry with mutual authentication between card and reader, and data encryption for both synchronous and asynchronous protocols.
