symmetric cipher

The Advanced Encryption Standard ( AES) issued by the National Institude of Standards and Technology ( NIST) of the USA in 2001, is supposed to replace DES, and has become the new widely-used symmetric block cipher standard.

高等加密标准（AES）是美国国家标准技术局（NIST）于2001年发布的，用于取代DES成为广泛应用的对称分组加密标准。
