Network Equipment Technologies Delivers Industry's First Wire-Speed, Full Capacity SRTP Solution

LAS VEGAS--(BUSINESS WIRE)--May 2, 2006-- Security Accelerator Module for NET VX Series Universal Voice Exchange Provides Line-Rate Encryption Based on Mocana's Embedded Security Suite

Industry pioneer Network Equipment Technologies, Inc. (NYSE:NWK) announced today the general availability of the VX Security Accelerator Module (SAM) for NET's VX Series Universal Voice Exchange. The VX SAM is the industry's first wire-speed, full-capacity solution using the secure real-time transport protocol (SRTP) and provides military-grade encryption utilizing Mocana's standards-based embedded IPsec/IKE and FIPS 140-2 certified cryptography libraries.

With the VX SAM, NET's VX Series is the industry's first voice switch providing SRTP encryption for SIP media streams. SRTP is used to encrypt the actual voice data and provides confidentiality, message authentication, and replay protection for RTP. The VX SAM provides line-rate SRTP and IPsec encryption as an optional module for secure voice solutions utilizing the VX Series. Interoperability tests with the latest SRTP RFC 3711 standards have been successfully completed.

"NET has long been a leader in secure voice solutions and our products are heavily relied upon by some of the most security conscious federal agencies," said Talbot Harty, VP of Marketing and General Manager of NET's VX Product Delivery Group. "With our VX SAM and Mocana's Embedded Security Suite, enterprises can now take advantage of high-performance, military-grade encryption to provide end-to-end secure voice communications."

Mocana's embedded IPsec/IKE implements a secure network layer that provides data integrity, origin authentication, data confidentiality, access control, partial sequence integrity and traffic flow confidentiality services to secure communications between any two networks or hosts. The Mocana solution is uniquely architected with an asynchronous core to fully leverage hardware acceleration.
