Description: This product provides the following features: Cisco IOS WebVPN (SSL) termination, IPv6 IPsec, Cisco IOS Secure Multicast (GDOI), DES, 3DES, AES (256), Layer 3 compression (IPPCP), hashing, key exchange, and SA storage.Cisco Systems supports AES in addition to the Data Encryption Standard (DES) and Triple DES (3DES) supported in Cisco IOS Software Release 12.2(13)T with IPsec. AES is privacy transform for IPsec and Internet Key Exchange (IKE). It uses a variable key length, the algorithm can specify a 128-bit key (default), a 192-bit key, or a 256-bit key. The AES feature adds support for the new AES encryption standard, with Cipher Block Chaining (CBC) mode, to IPsec.The National Institute of Standards and Technology (NIST) created AES as a new Federal Information Processing Standard (FIPS) publication. Computer scientists at the National Institute of Standards and Technology , an agency of the Commerce Department's Technology Administration, organized an international competition to develop a strong information encryption formula to protect sensitive information in federal computer systems. Researchers from 12 countries worked on the development of advanced encoding methods during the global competition, and NIST invited the worldwide cryptographic community to "attack" the encryption formulas in an attempt to break the codes. The standard selected was Rijndael, developed by for AES. The Rijndael developers are Belgian cryptographers Joan Daemen (pronounced Yo'-ahn Dah'- Minimize
