Implementation and Analysis of EFRS Technique for Intrusion Tolerance in Distributed Systems
This paper includes designing and implementing a
system that uses encryption-fragmentationreplication-
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.
