SEALSQ Files New Patent Application For Protection Technique Against Side-Channel Attacks On Polynomial Cryptographic Algorithms

The patent introduces a novel solution at the message encoding stage of polynomial-based PQC algorithms (such as NIST-standardized ML-KEM/Kyber). It hardens hardware implementations against side-channel attacks that exploit power consumption, electromagnetic emissions, or timing variations, a critical vulnerability even for mathematically robust post-quantum algorithms.
