AES uses the Rijndael 120 algorithm. 121 122 Rijndael appears to be consistently a very good performer in 123 both hardware and software across a wide range of computing 124 environments regardless of its use in feedback or non-feedback 125 modes. Its key setup time is excellent, and its key agility is 126 good. Rijndael's very low memory requirements make it very well 127 suited for restricted-space environments, in which it also 128 demonstrates excellent performance. Rijndael's operations are 129 among the easiest to defend against power and timing attacks. 130 131 On s390 the System z9-109 currently only supports the key size 132 of 128 bit. 133 134config S390_PRNG 135 tristate "Pseudo random number generator device driver" 136 depends on S390 137 default "m" 138 help 139 Select this option if you want to use the s390 pseudo random number 140 generator.
