The IP Security protocol (IPSec) is an important and widely used security protocol in the IP layer. But the implementation of the IPSec is a computing intensive work which greatly limits the performance of the high speed network. In this paper, a high performance IPSec accelerator used in a 10Gbps in-line Network Security Processor (NSP) is presented. The design integrates the protocol processing and the cryptographic processing; the transport/tunnel mode of the AH, ESP security protocols and the AES, HMAC-SHA-1 cryptographic algorithms are realized by hardware.
