Belgian block cipher developed by Dr. Joan Daemen and Dr. Vincent Rijmen. It was an AES candidate and has at length been selected by NIST as the proposed AES standard--a relative dark horse winner among hyped ciphers such as Twofish, RC6, and MARS, though the eminence of Dr. Rijmen is not to be understated. The neglect of Rijndael can probably be attributed more to its Belgian name than its underlying structure. (Pronounce it "Rhine Dahl" or "Rain Doll." Also, his name is Joan.)

The irony of the federal government instituting a foreign-made algorithm as a national standard when not long ago, at the beginning of the selection process, it could be treason to give cryptological instruction to a foreign national, is not to be lost.

A humorous tidbit from the submission paper: "Advantages: Simplicity of Design: The cipher is fully `self-supporting.' It does not make use of another cryptographic component, S-boxes `lent' from well-reputed ciphers, bits obtained from Rand tables, digits of pi or any other such jokes."
