密码学中的高级加密标准（Advanced Encryption Standard，AES），又称Rijndael加密法，是美国联邦政府采用的一种区块加密标准。这个标准用来替代原先的DES，已经被多方分析且广为全世界所使用。经过五年的甄选流程，高级加密标准由美国国家标准与技术研究院 （NIST）于2001年11月26日发布于FIPS PUB 197，并在2002年5月26日成为有效的标准。2006年，高级加密标准已然成为对称密钥加密中最流行的算法之一。-Cryptography Advanced Encryption Standard (Advanced Encryption Standard, AES), also known as Rijndael encryption method, is the U.S. federal government adopted a block encryption standard. This standard is used to replace the original DES, have been multi-analysis and widely used around the world. After five years of the selection process, the Advanced Encryption Standard by the National Institute of Standards and Technology (NIST) on November 26, 2001 Posted in FIPS PUB 197, and in May 26, 2002 as an effective standard. In 2006, the Advanced Encryption Standard has become symmetric key encryption algorithm is one of the most popular.
