  • AES - Advanced Encryption Standard

    This Standard is taking the place of 3DES.
    AES is a symmetric algorithm meaning the same key can be used for both encryption and decryption.
    The encryption algorithm in AES is the Rijndael algorithm which is a block cipher.
    Block ciphers are less CPU intensive as stream ciphers so they fit well in software. Stream ciphers use more CPU and are often placed in hardware.
    Unlike DES the Rijndael algorithm supports more than one key size. Rijndael support key sizes of 128, 192 and 256 bits. This is a major improvement over DES as it was hard coded to only use a 64 bit key and has a much higner Work Factor.
    AES is for encryption of sensetive but unclassified data.
