  • Method and circuit to accelerate IPSec processing
    Patent number: 7017042
    Abstract: Methods and apparatus' for performing IPSec processing on an IP packet being transmitted onto a network and being received from a network are described. The methods and apparatus' further described perform IPSec processing inline which results in a reduced number of transfers over the system bus, reduced utilization of system memory, and a reduced utilization of the system CPU. An IP packet which requires IPSec processing enters an acceleration device. In one embodiment, the acceleration device is coupled to a security policy database (SPD) and security association database (SAD). IPSec processing is performed at the acceleration device without sending the IP Packet to system memory for processing.

  • Method and circuit to accelerate secure socket layer (SSL) process
    Patent number: 6983382
    Abstract: Methods and apparatus' for performing SSL processing on an IP packet being transmitted onto a network and being received from a network are described. The methods and apparatus' further described performing SSL processing inline which results in a reduced number of transfers over the system bus, reduced utilization of system memory, and a reduced utilization of the system CPU. An IP packet that requires SSL processing enters an acceleration device. SSL processing is performed at the acceleration device without first sending the IP packet to system memory for processing.
