Abstract-- Secure group key distribution and efficient rekeying is one of the most challenging security issues in sensor networks at present. In this paper, Latin square is firstly...
In an e-commerce system, security, in particular authentication, is of paramount importance. Public-key Infrastructure is often used to enforce authentication and the property of ...
The term wireless sensor network is applied broadly to a range of significantly different networking environments. On the other hand there exists a substantial body of research on...
Abstract. This paper investigates a novel computational problem, namely the Composite Residuosity Class Problem, and its applications to public-key cryptography. We propose a new t...
Proxy re-encryption (PRE) allows a proxy to convert a ciphertext encrypted under one key into an encryption of the same message under another key. The main idea is to place as lit...
