AES加密算法 2000年10月，NIST（美国国家标准和技术协会）宣布通过从15种侯选算法中选出的一项新的密匙加密标准。Rijndael被选中成为将来的AES。 Rijndael是在 1999 年下半年，由研究员 Joan Daemen 和 Vincent Rijmen 创建的。AES 正日益成为加密各种形式的电子数据的实际标准。 美国标准与技术研究院 (NIST) 于 2002 年 5 月 26 日制定了新的高级加密标准 (AES) 规范。-AES encryption algorithm in October 2000, NIST (National Institute of Standards and Technology Association) announced candidates from 15 kinds of algorithm selected a new encryption standard keys. Rijndael was selected to become the future of the AES. Rijndael is the second half of 1999, by researcher Joan Daemen and Vincent Rijmen created. AES encryption is increasingly becoming the various forms of de facto standard for electronic data. United States Institute of Standards and Technology (NIST) in May 26, 2002 developed a new Advanced Encryption Standard (AES) norms.
