Designed to deliver consistent, high-quality results for the certification of cryptographic modules, our Differential Power Analysis (DPA) Countermeasure Validation Program is a comprehensive and rigorous security testing procedure that uses independent accredited testing labs.
Side-channel attacks conducted against electronic gear are relatively simple and inexpensive to execute. Such attacks include simple power analysis (SPA) and Differential Power Analysis (DPA). As all physical electronic systems routinely leak information, effective side-channel countermeasures should be implemented at the design stage to ensure protection of sensitive keys and data.
Licensed vendors with products that have successfully passed the independent security tests in the DPA Countermeasure Validation Program are permitted to use the DPA Lock™ logo on compliant products, packaging, and marketing materials.
The DPA security logo gives customers assurance of two main benefits:
1. The device implements effective DPA countermeasures, the effectiveness of which have been tested and verified by a qualifying independent testing lab, and
2. The product has obtained the necessary patent license from Cryptography Research
DPA Countermeasures are fundamental techniques for protecting against Differential Power Analysis (DPA) and related side-channel attacks. Consisting of a broad range of software, hardware, and protocol techniques, DPA Countermeasures include reducing leakage, introducing amplitude and temporal noise, balancing hardware and software, incorporating randomness, and implementing protocol level countermeasures.
