Achieving Distributed System Information Security
Salvatore Distefano, Antonio Puliafito · 2011
Distributed computing infrastructure's data storage subsystems are usually physically scattered among several nodes and logically shared among several users and (local) administrators. It is therefore necessary to provide users with adequate mechanisms and tools for information and data security management, especially in large scale systems since the complexity of the problem increases with the number of users and the amounts of data. In this paper we propose a solution based on a lightweight cryptography algorithm combining the strong and highly secure asymmetric cryptography technique (RSA) with the symmetric cryptography (AES). We describe a possible implementation of our solution going into details of all the algorithms and the mechanisms specified.
