Analysis conducted by security evaluation firm Brightsight (Delft, the Netherlands), has validated the effectiveness of Differential Power Analysis countermeasures in members of NXP Semiconductors' SmartMX secure microcontrollers.
DPA is a form of attack that involves monitoring variations in the electrical power consumption of a chip or device, then using statistical methods to derive cryptographic keys and other secrets. Strong countermeasures to DPA are required to protect tamper-resistant products used in banking, pay television, mass transit, secure ID, secure storage, automobiles, consumer electronics, wireless telecommunications and other applications.
The DPA Countermeasure Validation Program is a certification program administered by security experts at Cryptography Research Inc. (San Francisco, Calif.), and involves rigorous independent testing of products to evaluate their resistance to side-channel attacks. The testing program's goal is to enable chip purchasers and downstream customers to identify devices with effective security.
SmartMX secure microcontrollers are the first products to achieve certification under the DPA countermeasure validation program and NXP will now have the right to display the DPA Security logo in documentation and marketing literature associated with the certified products.
