Advanced Encryption Card (AEC)
Introduction Release 6.4 and greater supports the Advanced Encryption Standard (AES)
encryption for the Vanguard 7300 Series using the Advanced Encryption Card
(AEC). The 7300 AEC supports DES, 3DES, and AES.
Advanced
Encryption
Standard (AES) The Advanced Encryption Standard is a Federal Information Processing Standard
(FIPS), which specifies a cryptographic algorithm for use by organizations to protect
sensitive, classified information. AES provides a better combination of security and
speed than DES or Triple-DES. AES has more elegant mathematical formulas
behind it, and only requires one pass to encrypt data. AES was designed from the
ground up to be fast, unbreakable and able to support the smallest computing devices
imaginable. The big differentiators between AES and Triple-DES are the strength of
security, superior performance and better use of resources. AES provides faster
encryption and compatibility with the widest range of devices. Without AES, it
would be necessary to have different encryption technologies for application-specific
purposes, such as wireless e-mail, financial transactions or quality-of-service-
specific applications.
AES is defined for 128, 192 and 256 bit key lengths.
Release 6.4 and greater supports the 7300 Encryption Card for the
Vanguard 7300 Series. Please refer to the Virtual Private Network (VPN) Manual
(Part Number T0103-10) and the Encryption Manual (Part Number T0103-09) for
more information.
