Cryptography Research Licenses Differential Power Analysis Countermeasures Patents to STMicroelectronics

SAN FRANCISCO, USA November 16, 2009 Cryptography Research, Inc. (CRI) today announced an agreement with STMicroelectronics (NYSE: STM) regarding the use of CRI’s patents for protecting ST’s tamper-resistant chips against Differential Power Analysis (DPA) and related attacks.

Under the agreement, ST receives the freedom to use CRI's patents in ST’s products. The license also covers software executing on licensed ST chips, allowing ST’s customers to develop their own security countermeasures without a separate license from Cryptography Research.

“We are pleased to announce STMicroelectronics as a new licensee under the DPA countermeasures licensing program,” said Carole Coplan, Vice President of Tamper Resistance Solutions at Cryptography Research.

DPA is a form of attack that involves monitoring the fluctuating electrical power consumption of a target device and then using advanced statistical methods to derive cryptographic keys and other secrets. Strong countermeasures to DPA help protect tamper-resistant chips used in applications such as banking, pay television, mass transit, secure ID, and wireless telecommunications.

Cryptography Research has been awarded a portfolio of more than 50 patents covering countermeasures to DPA attacks.
