CoreStreet Joins Open Security Exchange

CoreStreet Will Work Closely with Consortium Members to Develop Vendor Neutral Standards to Converge Physical and Digital Security

Washington, DC—National Summit on Security, October 2, 2003

CoreStreet,a leading provider of validation and authorization technology, today announced that it has joined the Open Security Exchange (OSE), a program of the IEEE Industry Standards and Technology Organization (ISTO), promoting the integration between disparate components of security infrastructure.

CoreStreet will work closely with founding members Computer Associates, Gemplus, HID Corporation and Tyco Fire & Security Software House as well as with other new OSE members ActivCard, Fargo Electronics, Siemens SBT and VistaScape. Together, these companies will enhance vendor neutral interoperability specifications for converging physical and digital security technologies approved today by the Security Industry Association (SIA).

“The Open Security Exchange program welcomes the collective expertise and knowledge of CoreStreet’s management team as we work on standards related to the convergence of physical and digital security,” said Steve Rogala, program manager of Open Security Exchange. “We look forward to working with CoreStreet and the other member companies on the development of vendor neutral specifications that will provide end users with industry standards on implementing a security strategy in mixed environments.”

CoreStreet’s RTC technology works by sending small codes – as little as 20 bytes – called “proofs” to establish credential validation. The proofs can be used to determine the validity of a digital certificate or establish individual privileges or access rights. By eliminating the need for costly security measures such as encryption, server protection and secure communication lines, CoreStreet’s products greatly reduce installation, infrastructure and maintenance costs for security. This enables sophisticated cryptographic techniques once considered too slow and costly for mainstream applications to be embedded universally in millions of everyday devices.

“CoreStreet’s mission and the goals of OSE align perfectly,” according to Paul Ohrenberger, vice president of sales and marketing at CoreStreet. “CoreStreet’s Real Time Credential Suite provides an extremely cost-effective, high performance means for massively scalable validation with the same credentials across applications, so we are very knowledgeable about the different requirements necessary for physical and digital security. We are looking forward to sharing our knowledge with other OSE members in setting standards for interoperability across digital and physical security applications.
