| Use optimized AES assembler routines for ARM platforms. |
| |
| AES cipher algorithms (FIPS-197). AES uses the Rijndael |
| algorithm. |
| |
| Rijndael appears to be consistently a very good performer in |
| both hardware and software across a wide range of computing |
| environments regardless of its use in feedback or non-feedback |
| modes. Its key setup time is excellent, and its key agility is |
| good. Rijndael's very low memory requirements make it very well |
| suited for restricted-space environments, in which it also |
| demonstrates excellent performance. Rijndael's operations are |
| among the easiest to defend against power and timing attacks. |
| |
| The AES specifies three key sizes: 128, 192 and 256 bits |
