Hifn said Monday (Dec. 6) that Airspan Networks Inc. used its 7955 security co-processor during the design of an IEEE 802.16 WiMAX base station.

"We were looking for a suitable encryption solution for IEEE 802.16-2004, that would also be able to support the evolving 802.16e standard," said Jeremy Rowe, vice president of Airspan's UK-based engineering team. "The Hifn 7955 part met our requirements."

The Hifn 7955 security co-processor is designed for networking applications like virtual private networking (VPN) broadband routers, wireless access points, VPN edge router/gateways, firewall/VPN appliances, and other network and customer premise equipment.

The security engine in the 7955 accelerates a variety of IPsec and SSL/TLS protocols including DES, 3DES, AES (128, 192 and 256 bit with counter mode support), MD5, SHA-1, true random number generator and public key. In addition to supporting IPsec and SSL protocols, the 7955 security processor supports the temporal key integrity protocol (TKIP) and AES counter mode encryption with CBC-MAC protocol (CCMP). Compression engines are also provided to increase packet throughput.

The 7955 co-processor runs from a 1.5-V core voltage and 3.3-V I/O voltage. It is available now and is packaged in 144-pin TQPF.
