AES uses the Rijndael 121 algorithm. 122 123 Rijndael appears to be consistently a very good performer in 124 both hardware and software across a wide range of computing 125 environments regardless of its use in feedback or non-feedback 126 modes. Its key setup time is excellent, and its key agility is 127 good. Rijndael's very low memory requirements make it very well 128 suited for restricted-space environments, in which it also 129 demonstrates excellent performance. Rijndael's operations are 130 among the easiest to defend against power and timing attacks. 131 132 On s390 the System z9-109 currently only supports the key size 133 of 128 bit. 134 135config S390_PRNG 136 tristate "Pseudo random number generator device driver" 137 depends on S390 138 default "m" 139 help 140 Select this option if you want to use the s390 pseudo random number 141 generator.
