All applications utilizing cryptography in one way or another are heavy users of CPU time. To address this concern, Sun Microsystems designed the Crypto Accelerator I Board, a PCI card with the following features:
1024-bit RSA encryption
DH and DSA operations
Support for OpenSSL and Cryptokit 2.2
Accelerates SSL transaction by a factor of 5
Hardware true random-number generator
Supports both the Apache and iPlanet web servers
This board performs all mathematical calculations and dramatically decreases the CPU’s load.
