Cryptographic adapter
A 1090 system can emulate several cryptographic adapters as CEX3C devices.1 Each of the CEX3C emulated adapters runs as separate Linux processes and, if sufficient base processors are available to permit these threads to be dispatched in parallel by Linux, can run asynchronously with the 1090 CPs. CEX3C includes the following:
DES (56, 112, 168 bits), with encryption, decryption, MAC, and key management.
PIN processing (for credit cards).
AES (128, 192, and 256 bits), with encryption, decryption, and key management.
