Short for Advanced Encryption Standard, a symmetric 128-bit block data encryption technique developed by Belgian cryptographers Joan Daemen and Vincent Rijmen. The U.S government adopted the algorithm as its encryption technique in October 2000, replacing the DES encryption it used. AES works at multiple network layers simultaneously. The National Institute of Standards and Technology (NIST) of the U.S. Department of Commerce selected the algorithm, called Rijndael (pronounced Rhine Dahl or Rain Doll), out of a group of five algorithms under consideration, including one called MARS from a large research team at IBM.While the terms AES and Rijndael are used interchangeably, there are some differences between the two. AES has a fixed block size of 128-bits and a key size of 128, 192, or 256-bits, whereas Rijndael can be specified with any key and block sizes in a multiple of 32-bits, with a minimum of 128-bits and a maximum of 256-bits.
(2) Short for Audio Engineering Society, AES is a professional
standards
organization that is devoted exclusively to audio technology. Founded in 1948,
AES is an international organization with a mission of uniting audio engineers,
creative artists, scientists and students. AES currently has over
14,000 members and offers guest speakers, technical tours, demonstration,
scientific presentations and exhibitions. The organization is also involved in
the creation and maintenance of international standards in the areas of
digital
and analog audio engineering, communications technology, acoustics, media
preservation and creative practice.
