Hypergroupoids and cryptosystems

Journal of Discrete Mathematical Sciences and Cryptography, 2002
Abstract 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.

Multicast Cryptosystem: A Cryptosystem for Secure Multicast Communication

2008 IFIP International Conference on Network and Parallel Computing, 2008
The recent growth of multimedia group of applications is driving the need for secure multicast communication. Secure multicast communication in dynamic environments like wireless networks and grids are potentially of critical concern. As multicast group members move in and out of the group, in order to preserve confidentiality, it becomes imperative to

Paillier's cryptosystem revisited

Proceedings of the 8th ACM conference on Computer and Communications Security, 2001
We 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.

On the SAFER cryptosystem

1997
An abstraction and some desirable properties of the PHT layer as defined in SAFER are identified. These properties lead to the construction of 3071 other structures which could be used as alternative PHT layers. Results of preliminary investigations carried out on these structures to ascertain their suitability as alternatives are briefly discussed ...

An implementation of inter-organization cryptosystem based on RSA cryptosystem

2015 IEEE International Conference on Consumer Electronics - Taiwan, 2015
Conventional 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 redefine the inter-organization cryptosystem using the public-key cryptosystem.

Hybrid inter-organization cryptosystem using ElGamal cryptosystem

2015 IEEE International Conference on Consumer Electronics - Taiwan, 2015
Conventional 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 ...
