DPA Resistant Software Library

Overview

Addressing the growing demand for readily available solutions that implement Differential Power Analysis (DPA) countermeasures, we developed a family of cryptographic cores and software libraries that are designed to protect against side-channel attacks. Our DPA Resistant Software Library incorporates many of the commonly used cryptographic algorithms. This library is validated to resist first- and second-order DPA attacks in over 1 million traces.

The DPA Resistant Software Library is easy to deploy in a security software stack, and is highly flexible for integration with standard cipher modes such as Cipher Block Chaining (CBC), Electronic Code Book (ECB), etc. It implements advanced DPA countermeasures against side-channel attacks providing robust DPA resistance.

Our DPA resistance-proven library is easy-to-integrate into the application stack, providing chipmakers with a seamless solution that enables them to devote resources to differentiating features and reduce implementation time.
