Abstract: Murakami and Nasako proposed a knapsack public key cryptosystem in 2008. They claimed that their proposal is secure against some known attacks. In this paper, we propose a cryptanalytic ...
Abstract: We introduce for non-uniform messages a novel hybrid universal network coding cryptosystem (NU-HUNCC) in the finite blocklength regime that provides Post-Quantum (PQ) security at high ...
Abstract: Recently, a new image encryption algorithm based on chaos has been proposed [Circular inter-intra pixels bit-level permutation and chaos-based image encryption, Information Sciences, 355-356 ...
Abstract: In this paper, we extend Rabin public-key cryptosys-tern from its classical settings which is the domain of natural integers, ℤ N, to a new setting which is the domain of Gaussian integers ℤ ...
Abstract: This paper proposes a number of theorems and algorithms for the Chinese Remainder Theorem, which is used to solve a system of linear congruences, and the extended Rabin cryptosystem, which ...
Abstract: In the Internet of Things environment, the secure transmission of digital images has attracted much attention. To improve the confidentiality, we propose an image cryptosystem adopting a ...
Abstract: In this work, we describe the model of a new 4-D hyperchaotic system with no balance point and deduce that the new hyperchaotic system has a hidden attractor. We present a detailed ...
Abstract: This paper provides a cryptanalysis of a recently-proposed cryptosystem that uses a cascade of McEliece cryptosystems, the first using Goppa codes and the second using low-density ...
Abstract: Here, we report an asymmetric single-channel color image cryptosystem that employs phase retrieval based on an iterative phase-truncation (PT) scheme. For the proposed encryption process, ...
A total of 572 crimes related to the "Red Code" in the province of Cagliari alone from January 1st to October 31st 2025. This is the data provided by the Carabinieri of the Provincial Command: 119 ...
Barak Sella was 10 years old when prime minister Yitzhak Rabin was assassinated on the night of November 4, 1995. Thirty years later, Sella, an activist, educator, and community organizer, views that ...
