The ATHENE Leak project addresses side-channel-analysis-attacks (SCA) by developing a so-called natural leakage model, that is closer to the hardware than standard leakage models and thereby more precise and effective.

As full electrical simulations of complex hardware are usually to resource-intensive, common leakage models abstract the hardware on the register-transfer-level (RTL) and are thereby much more resource-friendly during simulations.

A natural leakage model combines the resource-friendliness with measured behavior of the hardware. Based on this model, the project aims to further adapt and develop performance-optimized countermeasures against SCA on PQC-Algorithms implemented on the RISC-V platform.

The intended project results (a natural leakage models and optimizations) can be used to support hardware engineers during the development, hardening and testing of hardware-based security solutions. Thereby the number of prototypes before final rollout of new hardware will be reduced, speeding up the development process and saving costs in the development and hardening process.
