A brief review of revocable ID-based public key cryptosystem

, 2016
SummaryThe design of ID-based cryptography has received much attention from researchers. However, how to revoke the misbehaviour/compromised user in ID-based public key cryptosystem becomes an important research issue. Recently, Tseng and Tsai proposed a

Safe and Quickest Medical Image Encryption Using Logistic Map Derived S‐Boxes and Galois Field

Computational and Mathematical Methods, Volume 2026, Issue 1, 2026.
The pseudorandomness, simplicity of use, and extreme sensitivity to even the slightest change in the initial value and handling parameters make chaotic maps attractive. The use of medical imaging to diagnose illnesses has grown in significance. These photographs need strong security measures because they are exchanged over public networks.

New Public Key Cryptosystem (First Version) [PDF]

, 2021
In this article, we propose a new public key cryptosystem, called \textbf{NAB}. The most important features of NAB are that its security strength is no easier than the security issues of the NTRU cryptosystem~\cite{Hoffstein96} and the encryption ...

PQ‐AuthN‐IIoT: A Lightweight, LWE‐Based Postquantum and Privacy‐Preserving Mutual Authentication Scheme for Resource‐Constrained Industrial IoT Systems

Journal of Computer Networks and Communications, Volume 2026, Issue 1, 2026.
The rapid expansion of the Industrial Internet of Things (IIoT) presents pressing challenges for secure, efficient, and privacy‐preserving communication among users, sensors, and cloud infrastructures. Existing lightweight authentication schemes, primarily based on classical cryptographic assumptions, are increasingly vulnerable to the emerging threat ...

A Centralized Key Management Scheme Based on McEliece PKC for Space Network

IEEE Access, 2020
Constrained by the limited resource, high-latency and high bit error rate, the existing group key management schemes for the space network are inefficient. To solve this problem, we proposed a centralized and identity-based key management scheme by using

Key distribution for heterogeneous public-key cryptosystems

Journal of Communications and Networks, 2013
The widespread use of cryptographic technologies is complicated by inconsistencies and duplication in the key management systems supporting their applications. The proliferation of key management systems or protocols also results in higher operational and infrastructure costs, and fails in interoperability.

Polynomial Representations of Weak Inverse Property Quasigroups and Their Role in Cryptographic Primitives

Journal of Mathematics, Volume 2026, Issue 1, 2026.
A connection between cryptography and polynomial functions is extremely significant. Mathematical performance of polynomials helps to enhance the cryptographic primitives, which are trustworthy as well as straightforward representation tools, in everyday use. In this research, explicit topological sequences Qf which correspond to degree‐based, distance‐

McEliece public key cryptosystem attack algorithm based on enumeration error vector

Tongxin xuebao, 2014
The research on the security of McEliece (M) public key cryptosystem was presented. The Hamming weight of error vector is less than the code length, and M public key cryptosystem based on Goppa code possesses low weight public code words. Considering the
