34 | help | ||
35 | This is the s390 hardware accelerated implementation of the | ||
36 | AES cipher algorithms (FIPS-197). AES uses the Rijndael | ||
37 | algorithm. | ||
38 | |||
39 | Rijndael appears to be consistently a very good performer in | ||
40 | both hardware and software across a wide range of computing | ||
41 | environments regardless of its use in feedback or non-feedback | ||
42 | modes. Its key setup time is excellent, and its key agility is | ||
43 | good. Rijndael's very low memory requirements make it very well | ||
44 | suited for restricted-space environments, in which it also | ||
45 | demonstrates excellent performance. Rijndael's operations are | ||
46 | among the easiest to defend against power and timing attacks. | ||
47 | |||
48 | On s390 the System z9-109 currently only supports the key size | ||
49 | of 128 bit. | ||

55 | help | ||
56 | Select this option if you want to use the s390 pseudo random number | ||
57 | generator. The PRNG is part of the cryptograhic processor functions | ||
58 | and uses triple-DES to generate secure random numbers like the | ||
59 | ANSI X9.17 standard. The PRNG is usable via the char device | ||
60 | /dev/prandom. | ||
