Nevertheless, it was + conceived by Joan Daemon and Vincent Rijmen, two Belgians, under the + name Rijndael and submitted to the AES selection process in 1997 + (http://www.nist.gov/aes). On Oct 2, 2000 it was announced as being + the selected algorithm for the AES. + + Rijndael is a variable-round iterated block cipher that supports + block and key sizes each ranging from 128 to 256 bits, in steps of + 64. The number of rounds is dependant on the block and key sizes and + varies from 10 for 128/128 to 14 for 256/256 block/key sizes. + + SPPED: N/A + + PATENTS and LICENSING: + Rijndeal/AES is free of patents. As beign AES, NIST will ensure that + this will stay so. + + KNOWN ATTACKS: + None of the following attacks is able to undermine the security of + AES, when used with the round numbers specified by the authors. + + The original Rijndael specification contains a truncated + differential attack on 4,5 resp. 6 round versions ("Square attack") + requiring 2^9, 2^11 resp. 2^32 plaintexts and 2^9, 2^40 resp. 2^72 + work. There is another truncated differential attack that leads to a + collision attack on 7 round 192 and 256 bit keysize Rijndael + requiring 2^32 plaintext encryptions and 2^140 work. Other authors + extend the original Square attack to 7 rounds of 192 and 256 bit + keysize, both with more that 2^184 work. Further improvements of + these techniques result in attacks against 7 and 8 round + variants. But the latter require almost all of the codebook.
