584fffc8 | 404 | AES cipher algorithms (FIPS-197). AES uses the Rijndael |
a2a892a2 AS |
405 | algorithm. |
406 | ||
407 | Rijndael appears to be consistently a very good performer in | |
584fffc8 SS |
408 | both hardware and software across a wide range of computing |
409 | environments regardless of its use in feedback or non-feedback | |
410 | modes. Its key setup time is excellent, and its key agility is | |
411 | good. Rijndael's very low memory requirements make it very well | |
412 | suited for restricted-space environments, in which it also | |
413 | demonstrates excellent performance. Rijndael's operations are | |
414 | among the easiest to defend against power and timing attacks. | |
