Cryptographic-based modules provide comprehensive security for VoIP devices as well as signaling and media channels

MISSISSAUGA, Ontario – (March 7, 2006)–As with any new technology, the security risks associated with voice-over Internet Protocol (VoIP) are not fully understood and dominant security protocols have not yet emerged. However by providing strong authentication and establishing trusted boot and secure key management in the device, manufacturers can take great strides towards thwarting attacks. To provide developers with the means to easily and cost-effectively secure devices as well as protect the signaling and media channels, Certicom Corp. (TSX: CIC) today launched Certicom Security for VoIP.

Certicom Security for VoIP is a flexible, standard-based solution for desktop VoIP handsets and mobile VoIP devices. The solution consists of multiple, integrated modules that implement key security protocols such as IPSec (IP security protocol), SSL/TLS (secure socket layer and transport layer security) and DTLS (Datagram Transport Layer Security protocol). It also provides the underlying cryptographic algorithms, trusted boot, secure provisioning and code signing technology, all of which are key to securing advanced applications such as IP Multimedia Subsystem (IMS) and Unlicensed Mobile Access communication (UMA).

"Manufacturers of VoIP devices need to carefully plan their security strategy at the outset to ensure they provide multi-level protection that doesn't significantly impact performance," said Rick Pitz, product manager for Certicom. "By ensuring their devices and access points are protected, device manufacturers can provide their customers with the assurance they need when rolling out their VoIP systems."
