Overview
RYDE is a digital signature scheme based on the hardness of solving the Rank Syndrome Decoding problem. It is designed to provide security against attacks by both classical and quantum computers and has been submitted to the NIST’s Post-Quantum Standardization Project.
Performance Overview
The tables below describe the sizes and performances of RYDE. Numbers reported refers to an optimized implementation using AVX2 instructions and have been obtained using an Intel Core i9-13900K (3 Ghz) CPU.
