222 | This is the s390 hardware accelerated implementation of the | ||
223 | AES cipher algorithms (FIPS-197). AES uses the Rijndael | ||
224 | algorithm. | ||
225 | |||
226 | Rijndael appears to be consistently a very good performer in | ||
227 | both hardware and software across a wide range of computing | ||
228 | environments regardless of its use in feedback or non-feedback | ||
229 | modes. Its key setup time is excellent, and its key agility is | ||
230 | good. Rijndael's very low memory requirements make it very well | ||
231 | suited for restricted-space environments, in which it also | ||
232 | demonstrates excellent performance. Rijndael's operations are | ||
233 | among the easiest to defend against power and timing attacks. | ||
234 | |||
235 | On s390 the System z9-109 currently only supports the key size | ||
236 | of 128 bit. | ||
