NIST's PQC standardization process is in the third round, and a first final choice between
one of three remaining lattice-based key-encapsulation mechanisms is expected by the end …

Abstract© The Institution of Engineering and Technology 2019. The modulus switching
technique has been used in some cryptographic applications as well as in cryptanalysis. For …

In LWE-based KEMs, observed decryption errors leak information about the secret key in the
form of equations or inequalities. Several practical fault attacks have already exploited such …

Abstract The quantum resistance Key Encapsulation Mechanism (PQC-KEM) design aims to
replace cryptography in legacy security protocols. It would be nice if PQC-KEM were faster …

This paper describes the limits of various" security proofs", using 36 lattice-based KEMs as
case studies. This description allows the limits to be systematically compared across these …

Lattice-based schemes are promising candidates to replace the current public-key
cryptographic infrastructure in wake of the looming threat of quantum computers. One of the …

Large-scale quantum computing poses a major threat to classical public-key cryptography.
Recently, strong “quantum access” security models have shown that numerous symmetric …

In this work, we provide new, tighter proofs for the\(T_ {RH}\)-transformation by Jiang et
al.(ASIACRYPT 2023), which converts OW-CPA secure PKEs into KEMs with IND-1CCA …

There are many proposed lattice-based encryption systems. How do these systems compare
in the security that they provide against known attacks, under various limits on …

A key step in Regev's (2009) reduction of the Discrete Gaussian Sampling (DGS) problem to
that of solving the Learning With Errors (LWE) problem is a statistical test required for …
