800-bit RSA private key signings per second
Hardware support for 2,048-bit keys
Extensive support for all SSL, TLS, and IKE modes
Integrated symmetric cryptography processor
Support for IPSec and SSL/TLS payload processing
Single-pass IPSec encryption and authentication
310-Mbps IPSec (3DES + MD5/SHA1)
200-Mbps ARC4 processing
Support for unlimited number of simultaneous sessions
Full performance with a different session for each packet
Integrated true hardware random number generator
Optimized prefetching PCI interface
Full performance maintained independent of any reasonable
PCI latency
PCI 2.2 interface, 32/64 bits, 33–66 MHz
0.22m-CMOS technology, 2.5V core, 3.3V I/0
Low-power design
256-TBGA package

Incorporates all the functions of competitive board-level
solutions at a fraction of the cost
800 RSA transactions per second, 4x–5x the speed of
competitive boards
Integrated chip can reduce price point of SSL accelerators from
thousands to hundreds of dollars
