Tensor-based trapdoors for CVP and their application to public key cryptography
, 1999 We propose two trapdoors for the Closest-Vector-Problem in lattices (CVP) related to the lattice tensor product.

On the McEliece Public-Key Cryptosystem [PDF]
, 1990 Based on an idea by Hin, the method of obtaining the original message after selecting k of n coordinates at random in the McEliece public-key cryptosystem is improved. The attack, which is more efficient than the attacks previously proposed, is characterized by a systematic method of checking and by a random bit swapping procedure.

Key-Insulated Public Key Cryptosystems [PDF]
, 2002 Cryptographic computations (decryption, signature generation, etc.) are often performed on a relatively insecure device (e.g., a mobile device or an Internet-connected host) which cannot be trusted to maintain secrecy of the private key. We propose and investigate the notion of key-insulated security whose goal is to minimize the damage caused by ...

Message transmission for GH-public key cryptosystem
, 2014 In this paper we propose an ElGamal type encryption scheme based on the concepts of public key cryptosystem over cubic finite field extension proposed by Gong and Ham (GH).

Cryptanalysis of a homomorphic public-key cryptosystem over a finite group
Journal of Mathematical Cryptology, 2007 The paper cryptanalyses a public-key cryptosystem recently proposed by Grigoriev and Ponomarenko, which encrypts an element from a fixed finite group defined in terms of generators and relations to produce a ciphertext from .

Advanced Quantum Technologies, Volume 9, Issue 5, May 2026.ABSTRACT Quantum‐native communication systems are reshaping secure, programmable, and coherence‐aware networking beyond the classical paradigm. As intelligent physical infrastructures, ranging from unmanned aerial vehicle swarms to satellite Quantum Key Distribution (QKD) platforms, demand trust, synchronization, and ultra‐reliability, conventional ...

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.

Structure a Public-Key Cryptosystem Based on HSS Algebra
, 2023 NTRU (Number theory research unit) is a public key cryptosystem that uses lattice-based cryptography. It is more resistant to assaults than other commonly used public-key cryptosystems, and its performance has been proven to be much better.
