"By linking up with an Israeli company specializing in
cryptographic technology, SGS-Thompson Microelectronics has
developed a family of monolithic cryptocomputers aimed at
high-security smart-card applications. The new devices combine
SGS-Thompson's ST16XYZ secure smart-card architecture with
cryptographic enhancements developed by Fortress U&T Ltd."
Summarizing the remainder - The approach is based on public key
encryption, speed is enhanced by a modular arithmatic coprocessor
developed by Fortress for very fast execution of modular
exponentiation operations. "A typical 512-bit signature calculation
can be performed 10 times faster than with the best performing
smart-card cryptoprocessor currently on the market.
The ST16CF54 will be followed by further devices, such as
the ST16KF74, capable of full-speed X.25 communications."
