Implementation & Analysis of EFRS Technique for Intrusion Tolerance in Distributed Systems
This paper includes designing and implementing a system that uses encryption-fragmentation replication-scattering for the purpose of developing secure and dependable data storage within a distributed system. The system will consist of one central node which is assumed to be trusted and multiple storage nodes. Data is collected at the central node, which is then encrypted followed by fragmentation. Data fragments then undergo a hash function to give unique hash value of each fragment. These fragments are then replicated and scattered over the network. Thus, the system continues to provide service even in case of failure of some storage nodes.
