SKE2SG: A Secure Key Establishment Scheme for Smart Grid Cyber‐Physical Systems Based on Elliptic Curve Cryptography

IET Cyber-Physical Systems: Theory &Applications, Volume 11, Issue 1, January/December 2026.
Recent proposals by Mahmood et al., Braeken et al., and Chaudhry et al. aimed at establishing secure communication in AMI, asserting their methods fulfil the requisite security criteria. This paper, however, reveals that each of these proposals exhibits security vulnerabilities and lacks sufficient features for deployment.

Timing Attacks against the Syndrome Inversion in Code-Based Cryptosystems [PDF]

, 2013
In this work we present the first practical key-aimed timing attack against code-based cryptosystems. It arises from vulnerabilities that are present in the inversion of the error syndrome through the Extended Euclidean Algorithm that is part of the decryption operation of these schemes.

CODE-BASED HYBRID CRYPTOSYSTEM: COMPARATIVE STUDIES AND ANALYSIS OF EFFICIENCY

International Journal of Computing, 2019
In this paper the basic principles of construction and operation of McEliece and Niederreiter cryptosystems based on the use of error-correcting codes were considered. A new hybrid cryptosystem that combines the rules of encryption according to the above-mentioned schemes is proposed.

polarRLCE: A New Code-Based Cryptosystem Using Polar Codes

Security and Communication Networks, 2019
Security challenges brought about by the upcoming 5G era should be taken seriously. Code-based cryptography leverages difficult problems in coding theory and is one of the main techniques enabling cryptographic primitives in the postquantum scenario. In this work, we propose the first efficient secure scheme based on polar codes (i.e., polarRLCE) which

Modern variations of McEliece and Niederreiter cryptosystems

Научно-технический вестник информационных технологий, механики и оптики
Classical cryptosystems proposed by Robert McEliece (1978) and Harold Niederreiter (1986) and their modern variations are studied. A detailed review of five code-based public key cryptosystems has been presented.
