For Immediate Release

InterWorking Labs Adds Diffie-Hellman Key Management Function to SilverCreek SNMP Test Suite

New Support Module for Diffie-Hellman Security Allows Cable Modem Makers to Assess DOCSIS 1.1 Security

ATLANTA (September 25, 2000) - At Networld+Interop 2000 Atlanta, InterWorking Labs, creators of the only official solutions to accurately test a product's fidelity and interoperability with Internet management standards, announced the release of a new test module for Diffie-Hellman key ignition and key change. The Diffie-Hellman test module has been added to InterWorking Labs' SilverCreek SNMP test suite to validate support for Diffie-Hellman key agreement, and will be of particular value to makers of cable modems (CM) and cable modem termination system (CMTS), since Diffie-Hellman key ignition and key change functions are specified in the DOCSIS 1.1, the Data Over Cable Service Interface Specification.

SilverCreek is the only official test suite for SNMPv3 conformance, and SNMPv3 forms the basis for Diffie-Hellman (RFC 2786) support in the DOCSIS standard, including SNMPv3 key ignition and key change functionality for CM and CMTS equipment. It is this Diffie-Hellman key initialization and key update mechanism that allows cable companies to authorize data services to customers, and provide data access services through their infrastructure.

"We have been actively working with CableLabsĀ® for more than a year now, providing SNMP testing for next-generation cable modems and cable modem termination systems through SilverCreek," said Chris Wellens, president and CEO of InterWorking Labs. "With this new Diffie-Hellman testing module, we will be able to offer a comprehensive SNMP test solution to cable hardware manufacturers, helping them shorten time-to-market and assure interoperability for the next generation of cable modem hardware."

Dr. Martin Hellman of Stanford University and two of his graduate students, Ralph Merkle and Whitfield Diffie, invented the Diffie-Hellman secure key exchange method in 1976. The technique is currently used in a wide array of technology products, including firewalls and e-mail, and is one of many security strategies that can be deployed with SNMPv3. The cable modem market has adopted Diffie-Hellman as its authentication methodology for Internet access. Cable Television Labs (CableLabs), the research and development consortium of cable television system operators, is responsible for validating conformance to the latest industry standards, and uses InterWorking Labs' SilverCreek test suite, to test cable modems for SNMP compatibility, as specified in DOCSIS 1.1.

About SilverCreek

SilverCreek, the SNMP Test Suite, is the official industry standard for finding and fixing bugs in SNMP product implementations. SilverCreek features more than 650 standards conformance tests for standards maintained by the Internet Engineering Task Force (IETF), including a full complement of tests to verify compliance with the newest features added with the release of SNMPv3. SilverCreek tests compliance with a range of RFC standards, including new RFCs to cover management frameworks (RFC 2571), message processing (RFC 2572), applications (RFC 2573), user-based security model (RFC 2574), view based access control model (rfc2575), and much more. An indispensable tool for design engineers, product developers, software quality engineers and testers, SilverCreek has revolutionized the process of testing network products.
