A Distinguisher for High-Rate McEliece Cryptosystems [PDF]
IEEE Transactions on Information Theory, 2011 The Goppa Code Distinguishing (GD) problem consists in distinguishing the matrix of a Goppa code from a random matrix. The hardness of this problem is an assumption to prove the security of code-based cryptographic primitives such as McEliece's cryptosystem. Up to now, it is widely believed that the GD problem is a hard decision problem. We present the

Noise Modulation‐Based Reversible Data Hiding with McEliece Encryption
Security and Communication Networks, Volume 2022, Issue 1, 2022., 2022 McEliece cryptosystem is expected to be the next generation of the cryptographic algorithm due to its ability to resist quantum computing attacks. Few research studies have combined it with reversible data hiding in the encrypted domain (RDH‐ED). In this article, we analysed and proved that there is a redundancy in the McEliece encryption process that ...

Post-Quantum Biometric Authentication Based on Homomorphic Encryption and Classic McEliece
Applied Sciences, 2023 Homomorphic encryption is a powerful mechanism that allows sensitive data, such as biometric data, to be compared in a protected way, revealing only the comparison result when the private key is known.

Security and Communication Networks, Volume 2022, Issue 1, 2022., 2022 The existing reversible data hiding methods in encrypted domain separate image encryption from information embedding and do not make full use of the redundant space in the process of image encryption. In order to improve the performance of reversible data hiding by using the technical characteristics of image encryption, a reversible data hiding method

Attacking and Defending the McEliece Cryptosystem [PDF]
, 2008 This paper presents several improvements to Stern’s attack on the McEliece cryptosystem and achieves results considerably better than Canteaut et al. This paper shows that the system with the originally proposed parameters can be broken in just 1400 days by a single 2.4GHz Core 2 Quad CPU, or 7 days by a cluster of 200 CPUs.

Post‐Quantum Secure Password‐Authenticated Key Exchange Based on Ouroboros
Security and Communication Networks, Volume 2022, Issue 1, 2022., 2022 Password‐authenticated key exchange (PAKE) protocols play an important role in cryptography. Most of PAKEs are based on the Diffie–Hellman key exchange protocols or RSA encryption schemes, but their security is threatened by quantum computers. In this study, we propose the first code‐based PAKE protocol based on Ouroboros, which is a code‐based key ...

Survey of Graph Neural Networks and Applications
Wireless Communications and Mobile Computing, Volume 2022, Issue 1, 2022., 2022 The advance of deep learning has shown great potential in applications (speech, image, and video classification). In these applications, deep learning models are trained by datasets in Euclidean space with fixed dimensions and sequences. Nonetheless, the rapidly increasing demands on analyzing datasets in non‐Euclidean space require additional research.

Generalized Concatenated Codes over Gaussian and Eisenstein Integers for Code-Based Cryptography
Cryptography, 2021 The code-based McEliece and Niederreiter cryptosystems are promising candidates for post-quantum public-key encryption. Recently, q-ary concatenated codes over Gaussian integers were proposed for the McEliece cryptosystem, together with the one-Mannheim ...
