Abstract
An IPSec processor is a network security device. It is designed primary for an environment requesting for a throughput of Gigabits per second. By using a new architecture, the parallel processing and pipeline processing become more efficient, thereof higher performance. An IPSec Core in the IPSec processor employs the sharing structure, which raise the utility of the Encryption Engine and Authentication Engine. Moreover, the IPSec Core can be duplicated, allowing a parallel processing. Because the IPSec Core deals with IPSec processing, the Pre_Operation, operation, and post_operation, it becomes a complete set of processing unit and easy for duplicating. In addition, several features have been created for a hardware base implementation, including the processing of the bundled SA case, early verification of the packet, and no need to build an additional context in order to perform a crypto operation.
