DPA Resistant Software Libraries are a portfolio of unique products that provide performance optimized, quantifiable side-channel resistant security for embedded software systems with seamless integration across a wide range of applications. Our software libraries come in two main varieties, platform neutral C-code which is designed to run on any platform and optimized code for ARM Cortex platforms, providing a wide range of device design options.
The DPA Resistant Software Libraries offer OEMs an easy-to-integrate software package that is resistant to first and second order DPA attacks, allowing them to have strong security without the need of specific security hardware.
Our high performance software libraries offer application builders an easy-to-integrate software security solution with built-in quantifiable side-channel resistance. The libraries are validated by Rambus for performance across a range of compilers and processors to protect against key extraction of up to 1 million traces, compared to 1 to 10K traces for non-protected implementations like Gladman reference code or other commercial and open source crypto libraries.
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.
Side-channel attacks comprise a wide range of techniques including Differential Power Analysis, Simple Power Analysis, Simple Electromagnetic Analysis, Differential Electromagnetic Analysis, Correlation Power Analysis and Correlation Electromagnetic Analysis. An effective layer of side-channel countermeasures should therefore be implemented via hardware (DPA resistant cores), software (DPA resistant libraries) or both. After layered countermeasures have been implemented, systems should be carefully evaluated to confirm the cessation of sensitive side-channel leakage.
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.
