Cryptography Research Announces License Agreement with Toshiba Corporation for Differential Power Analysis Countermeasure Patents
April 2010 by Marc Jacob
Cryptography Research, Inc. today announced an agreement with Toshiba Corporation regarding the use of CRI’s patents to enhance the security of Toshiba’s tamper-resistant products against Differential Power Analysis (DPA) and related attacks.
Under the agreement, Toshiba receives the freedom to use CRI’s patents as part of its strategy to develop and enhance its secure products, including smart cards and other applications. The license also covers software executing on licensed Toshiba products, allowing Toshiba’s customers to develop their own security countermeasures without a separate license from 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 products used in applications such as banking, pay television, mass transit, secure ID, and wireless telecommunications.
Cryptography Research has been awarded a portfolio of over 50 patents covering countermeasures to DPA attacks, with additional patent applications pending.
