The RSA public-key cryptosystem is an algorithm that converts input data to an unrecognizable encryption and converts the unrecognizable data back into its original decryption form...
Web Services and Service-Oriented Architecture (SOA) has been playing an important role as a middleware for interoperable transactions such as Business-to-Business and Enterprise A...
Despite recent developments in higher-level middleware for the Grid supporting high level of ease-of-programming, hurdles for widespread adoption of Grids remain high, due to (1) ...
Considering the solution of dynamic access problems in a user hierarchy, a novel scheme based on one-way hash function is proposed to manage the cryptographic keys in the paper. T...
Most present symmetric encryption algorithms result from a tradeoff between implementation cost and resulting performances. In addition, they generally aim to be implemented effici...
