NTRU announces F@stWTLS, The Fast, Low-Footprint Wireless Security Solution For WAP

High Speed, Small Footprint, Low Battery Consumption are Key Features

Boston, MA -- January 19, 2000 -- NTRU Cryptosystems, Inc. today announced the development of F@stWTLS(tm), the world's fastest wireless data security solution. F@stWTLS is an implementation of the Wireless Access Protocol (WAP) Wireless Transport Layer Security (WTLS) using NTRU's patented public key cryptography system. NTRU operates over 100 times faster than competitors such as RSA (Nasdaq:RSAS) and Certicom's (Toronto:CIC) Elliptic Curve Cryptosystem at equivalent security levels.

"Wireless data applications require fast, cost-effective security," said Scott Crenshaw, NTRU Vice President of Business Development. "F@stWTLS operates dramatically faster than competitors, increasing response times, reducing gateway loading and increasing security by allowing more communications to be encrypted at a higher security level than before."

"F@stWTLS reduces device cost and increases battery life," said Jim Kotanchik, NTRU Vice President of Engineering. "By utilizing fewer gates and fewer processor cycles, NTRU delivers high security at a lower cost. We believe these benefits are compelling to everyone in the wireless data market, from manufacturers to network operators and consumers."

Key benefits of F@stWTLS include:

• Fast performance
• Small memory footprint
• Low cost to implement in hardware
• Increased gateway performance (supports more users with fewer servers)
• Lower battery consumption

NTRU is the most computationally efficient secure public key cryptography system available. NTRU delivers performance 100 times faster than competitors, even on inexpensive embedded microprocessors. It has a very small memory footprint, and if implemented in silicon has the smallest gate count in the industry. The computational efficiency also results in very low battery consumption, a key point for wireless devices.

Disposable Keys

NTRU's fast operation enables the new security paradigm known as Disposable Keys. With NTRU, every wireless transaction can be encrypted using a different, unrelated public key. Breaking one transaction yields no benefits to help break another. Competing cryptography systems use the same key for many transactions, often retaining the key for months at a time. Some devices have only one key, which is used for the life of the device. By breaking that one key, a hacker gains access to the contents of perhaps hundreds or thousands of transactions. NTRU eliminates this risk by enabling disposable keys.

F@stWTLS is currently under development, with release expected in early 2000. Interested launch customers are invited to contact NTRU immediately.
