Some VIA processors come with an integrated crypto engine

(so called VIA PadLock ACE, Advanced Cryptography Engine)
|

that provides instructions for very fast cryptographic

operations with supported algorithms.

The instructions are used only when the CPU supports them.

Otherwise software encryption is used.

This is the s390 hardware accelerated implementation of the
|
|
AES cipher algorithms (FIPS-197). AES uses the Rijndael
|
|
algorithm.
|
|
|
|
Rijndael appears to be consistently a very good performer in
|
|
both hardware and software across a wide range of computing
|
|
environments regardless of its use in feedback or non-feedback
|
|
modes. Its key setup time is excellent, and its key agility is
|
|
good. Rijndael's very low memory requirements make it very well
|
|
suited for restricted-space environments, in which it also
|
|
demonstrates excellent performance. Rijndael's operations are
|
|
among the easiest to defend against power and timing attacks.
|
|
|
|
On s390 the System z9-109 currently only supports the key size
|
|
of 128 bit.
