Cryptography Research Inc. announced that it has signed an agreement with Samsung Electronics Co. Ltd. regarding the use of the company’s patents to enhance the security of Samsung’s smart card chips against Differential Power Analysis and related attacks.
Under the agreement, Samsung can use Cryptography Research’s patents as part of its strategy to develop and enhance its security chips used in smart cards. The license also covers software executing on Samsung chips, enabling Samsung’s customers to develop their own security countermeasures without a separate license from CRI.
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. Countermeasures to DPA help protect smart cards used in applications such as banking, pay television, mass transit, secure ID and wireless telecommunications. ![[end]](/resources/bullet/archive-4.gif)
