Hypergroupoids and cryptosystems
Journal of Discrete Mathematical Sciences and Cryptography, 2002Abstract The GW-hypergroupoids are defined as generalization of the Wall hypergroupoids. The authors introduce a system to obtain a ciphertext using a GW-hypergroupoid. Conditions are given on the GW-hypergroupoid to univocally decipher a given ciphertext and to protect the original message and the key.

Paillier's cryptosystem revisited
Proceedings of the 8th ACM conference on Computer and Communications Security, 2001We re-examine Paillier's cryptosystem, and show that by choosing a particular discrete log base g, and by introducing an alternative decryption procedure, we can extend the scheme to allow an arbitrary exponent e instead of N. The use of low exponents substantially increases the efficiency of the scheme.

Hybrid inter-organization cryptosystem using ElGamal cryptosystem
2015 IEEE International Conference on Consumer Electronics - Taiwan, 2015Conventional cryptosystems are supposed to be used for the personal communication. However, the secure and effective communication system is more and more required for inter-organization cryptosystem. In this paper, we define the framework of the hybrid-type inter-organization cryptosystem and we propose a hybrid-type inter-organization cryptosystem ...

The Spline Cryptosystem has succeeded two major achievements: First, the system is based on real arithmetic which is generally considered unapplicable to cryptography because the information is lost through round-off errors.

Abstract This chapter introduces a number of historical cryptosystems, including the Simple Substitution Cipher, Playfair Cipher, Vigenère Cipher and homophonic encoding, none of which are suitable for modern use. The main aim of doing so is to illustrate the basic concepts and terminology of cryptography in a series of relatively simple

Abstract Historical ciphers, including the Caesar Cipher and the Simple Substitution Cipher, are described. Properties of natural language relevant to these ciphers and natural language statistics are discussed. The number of keys of these historical ciphers is determined and their security against exhaustive key search is discussed ...
