Abstract The Classic McEliece cryptosystem is one of the most trusted quantum-resistant
cryptographic schemes. Deploying it in practical applications, however, is challenging due to …

Quasi-cyclic moderate density parity check codes 1 allow the design of McEliece-like public-
key encryption schemes with compact keys and a security that provably reduces to hard …

McEliece-like code-based key exchange mechanisms using QC-MDPC codes can reach
IND-CPA security under hardness assumptions from coding theory, namely quasi-cyclic …

Post-quantum cryptography aims at securing exchanges against an adversary with a
quantum computer. One approach considered to achieve post-quantum public key …

Two variations of the McEliece cryptosystem are presented. The first is based on a relaxation
of the column permutation in the classical McEliece scrambling process. This is done in such …

Quantum computer attacks could easily jeopardize the total security of currently employed
encryption systems. As a result, there is an ongoing collaborative effort to design post …

In this paper, we introduce a new family of lattices, namely QC-MDPC lattices, which are a
special case of LDPC lattices, and an improved bit flip** algorithm for decoding of these …

The McEliece cryptosystem based on quasi-cyclic moderate-density parity-check with
adaptive chosen-ciphertext attack conversion is secure against information set decoding …

This paper presents a modified bit-flip** (BF) decoding algorithm for moderate-density
parity-check codes using a property of the number of unsatisfied parity checks (NUPCs) in …
