Exploiting Intermediate Value Leakage in Dilithium: A Template-Based Approach

Exploiting Intermediate Value Leakage in Dilithium: A Template-Based Approach

This paper presents a new profiling side-channel attack on CRYSTALSDilithium, the new NIST primary standard for quantum-safe digital signatures. An open source implementation of CRYSTALS-Dilithium is already available, with constant-time property as a consideration for side-channel resilience. Howe...
