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. 50 51config S390_PRNG 52 tristate "Pseudo random number generator device driver" 53 depends on S390 54 default "m" 55 help 56 Select this option if you want to use the s390 pseudo random number 57 generator. The PRNG is part of the cryptographic 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. 61
