Hardware Security Engine

The security engine (SEC 2.2) on the MPC8323E and MPC8321E allows CPU-intensive cryptographic operations to be off-loaded from the main CPU core. The security-processing accelerator provides hardware acceleration for DES, 3DES, advanced encryption standard (AES), secure hash algorithm (SHA)-1 and MD-5 algorithms.

MPC8323E has HW Security Engine, SEC2.2.

Is there a same level HW acceleration block in Qoriq series?

LS1020A and LS1021A provide SEC 5.4.

Tell me details of SEC5.4 please.

Thank you.

Yes, SEC engine on QorIQ family processors provide the same or higher level of acceleration

compared to that of MPC83xx.

The programming interface, however, is completely different. Starting from SEC4.x, there is

no back compatibility in the engine programming interface to SEC3.x and earlier.

Detailed description of LS1020/21 security accelerator is provided in a separate document

which requires NDA. Contact your distributor for details.

Have a great day,
Platon
