NTRU Presents RFID Demo Featuring Philips' MIFARE PROX and NTRU Security

NTRU RFID Security Pavilion to Demonstrate Innovations in Secure RFID Technologies

Burlington, Mass. - February 20, 2002 - NTRU, the only provider of strong security that fits everywhere, presents a demonstration of next generation secure radio frequency identification (RFID) technology at the RSA Conference in San Jose, February 18-22. The demonstration will feature a side-by-side digital signature comparison with other leading security technologies running on Philips Semiconductors' high-security MIFAREâ PROX dual interface smart card controller ICs to illustrate the speed, cost and read range advantages of NTRUSign. The demonstration can be viewed at NTRU's RFID Security Pavilion, booth #521, at the RSA Conference.

"The NTRU public key cryptography system is the only solution with the ability to deliver strong, efficient security to a full range of RFID applications and products," said Scott Crenshaw, CEO of NTRU. "The size and speed advantages of NTRU technology allows for reduced costs, reduced power consumption and increased read range, thereby significantly expanding the market for RFID applications. NTRU has created a faster and smaller security solution that will bring a new level of trusted transmission to a new breed of RFID applications."

As RFID applications proliferate, and more high-value transactions are performed using these applications, the need for powerful security increases. With NTRUSign, RFID applications benefit from authentication capabilities, which ensure that the tag, reader and/or system component is who or what they claim to be and that the transmitted data have not been altered. NTRU technology also provides for confidential transaction and new audit capabilities that create digitally signed records of each and every transaction.
