DPA is a form of attack that involves monitoring the fluctuating electrical power consumption of a target device and then using statistical methods to derive cryptographic keys and other secret information from that device. Strong DPA countermeasures are important for securing mobile devices, bank cards, pay television systems, secure identity products, secure storage media, anti-tamper products, and other electronic systems and components. Many of the world’s leading security standards require that devices be protected against DPA and related attacks.

CRI has developed a portfolio of over 55 US and international patents covering countermeasures to DPA attacks, with additional patent applications pending worldwide. For additional information on CRI and DPA countermeasures visit www.cryptography.com.
