Security Processor
Broadband Security Bargain
New Value-Priced Chip Powers High-Speed Small Office VPNs
DSL, cable modems and other broadband applications demand hardware security accelerationas much as 50-100 MIPS for IPSec processing. Now you can design in the strongest virtual private network security without sacrificing performance or spending big bucks on the wrong solution.
Compression
Soups up 3-DES and Public Key Processing
The 7901 crunches through compression, encryption and authentication algorithms at speeds that leave general-purpose CPUs in the dust. And, you get a true random number generator and Public Key acceleration, all on the same affordable all-purpose chip.
Encryption
· DES · Triple-DES · ARC4*
Authentication
· SHA-1 · MD5 Saves Money, Time and Board Space
At less than $20,* our new 7901 security processor fits within your budget and on your motherboard. Plus, the feature-packed 7901's glueless interface reduces chip count and design time.
Public Key
· RSA, DH · Hardware random number generator
Internal Packet Memory
