Side Channel Attacks On Post Quantum Cryptography Post quantum cryptographic algorithms are inherently more complex and significantly newer, with implementation practices that are still maturing. this combination of novelty and complexity increases their exposure to side channel vulnerabilities. While post quantum cryptographic (pqc) schemes are designed to resist quantum and classical mathematical cryptanalysis, their physical instantiations remain vulnerable to implementation level attacks—especially side channel attacks (scas).
Pdf Side Channel Analysis Of Post Quantum Cryptography In this work, we take a look at two previously proposed low cost countermeasures: the ciphertext sanity check and the decapsulation failure check, and demonstrate successful attacks on these. Post quantum cryptography (pqc) is designed to be secure against attacks from quantum computers, yet it remains vulnerable to classic side channel attacks (scas), which exploit physical implementation leaks. In this work, we present a systematic study of side channel attacks (sca) and fault injection attacks (fia) on structured lattice based schemes, with main focus on kyber key encapsulation mechanism (kem) and dilithium signature scheme, which are leading candidates in the nist standardization process for post quantum cryptography (pqc). "based on our assessment of the internal evaluation report, pqshield follows industry best practices to showcase base level first order side channel resistance of their post quantum crypto implementations".
Post Quantum Cryptography Can Help Us Mitigate Quantum Attacks Coins In this work, we present a systematic study of side channel attacks (sca) and fault injection attacks (fia) on structured lattice based schemes, with main focus on kyber key encapsulation mechanism (kem) and dilithium signature scheme, which are leading candidates in the nist standardization process for post quantum cryptography (pqc). "based on our assessment of the internal evaluation report, pqshield follows industry best practices to showcase base level first order side channel resistance of their post quantum crypto implementations". Section 3 reviews side channel attacks and countermeasures regarding post quantum cryptography in the order of code based, hash based, isogeny based, lattice based, and multivariate based families. Following this trend, in this chapter, we evaluate side channel leakages of existing pqc implementations using pqc sep, a completely automated side channel evaluation platform at both pre and post silicon levels. Post quantum cryptography guarantees the security of the algorithm through mathematical theories, but it is vulnerable to side channel attacks in specific implementation and applications, which will seriously threaten the security of post quantum cryptography. While standardized schemes such as crystals kyber, crystals dilithium, and sphincs offer strong theoretical security, practical deployments remain susceptible to physical layer vulnerabilities, notably side channel attacks (scas).
