Toshiba licenses anti-hacking patents for smartcards

Toshiba has licensed a set of patents owned by Cryptography Research for use in smartcards and other products that need protection against hackers using differential power analysis and similar attacks.

The licence 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.
“Differential power analysis countermeasures is one of the key technologies in security applications,” said Toshiya Watanabe, technology executive for system LSI at Toshiba Semiconductor.  
“Toshiba is a leading chip supplier in Japan and around the world for a variety of semiconductor form factors and applications utilising security, from smartcard chips to secure storage media and ASICs,” said Carole Coplan, vice president of business development, tamper resistance solutions at Cryptography Research. “We are pleased to include Toshiba among our list of leading licensed chip suppliers.”
Differential power analysis 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.
