2.3

Security Engine

The security engine is optimized to handle all the algorithms associated with IPSec, 802.11i, and iSCSI.

The security engine contains one crypto-channel, a controller, and a set of crypto execution units (EUs).

The execution units are:

•

Public key execution unit (PKEU)

— RSA and Diffie-Hellman (to 4096 bits)

— Programmable field size up to 2048 bits

— Elliptic curve cryptography (1023 bits)

— F2m and F(p) modes

— Programmable field size up to 511 bits

•

Data encryption standard execution unit (DEU)

— DES, 3DES

— Two key (K1, K2) or three key (K1, K2, K3)

— ECB, CBC, CFB-64 and OFB-64 modes for both DES and 3DES

•

Advanced encryption standard unit (AESU)

— Implements the Rinjdael symmetric key cipher

— Key lengths of 128, 192, and 256 bits

— ECB, CBC, CCM, CTR, GCM, CMAC, OFB, CFB, XCBC-MAC and LRW modes

— XOR acceleration

•

Message digest execution unit (MDEU)

— SHA with 160-bit, 256-bit, 384-bit and 512-bit message digest

— SHA-384/512

— MD5 with 128-bit message digest

— HMAC with either algorithm

•

Random number generator (RNG)
