ABSTRACT
A configurable IPSec processor for a high performance in-line network security processor that integrates two embedded 32-bit CPU cores, and an IPSec protocol processor on a SoC is presented. The IPSec processor can implement the transport/tunnel mode AH and ESP protocol of the IPSec, and support AES-128/192/256, HMAC-SHA-1 algorithm. The number of AH, ESP, AES, HMAC-SHA-1 IP-cores in the design can be configured for different use such as 10 Gigabit Ethernet and Gigabit Ethernet, even for the next generation 40/100G Network. Low power is also considered in the design. In the IPSec processor, crossbar switch architecture for multi-core data transfer is adopted. With four parallel AH, ESP, AES, HMAC-SHA-1 IP-cores separately connected to an 8x8 crossbar switch in the IPSec processor, a throughput of 1.5Gbps at 200MHz is achieved and hardware verification is implemented by FPGA. By simulation, the IPSec protocol operation can achieve 10Gbps wire speed with 32 IPSec protocol IP-cores and cryptographic IP-cores configured in the IPSec processor.
