Abstract
The invention provides mechanisms for transferring processor control of secure Internet Protocol (IPSec) security association (SA) functions between a host and a target processing devices of a computerized system, such as processors in a host CPU and a NIC. In one aspect of the invention, the computation associated with authentication and/or encryption is offloaded while the host maintains control of when SA functions are offloaded, uploaded, invalidated, and re-keyed. The devices coordinate to maintain metrics for the SA, including support for both soft and hard limits on SA expiration. Timer requirements are minimized for the target. The offloaded SA function may be embedded in other offloaded state objects of intermediate software layers of a network stack.
