Optimized Key Encryption for Digital Forensic Security

Abstract

The research areas of digital forensics are subject to Blockchain (BC) technology implementation and enhanced over the current alternative introduced in this publication and capable of addressing certain grave issues, which are concomitant with data collection and preservation of digital evidence. Another puzzle that is resolved by the blockchain is the inherent transparency, immutability that central storing data is extremely prone, and the blockchain ensure that this does not happen, as it provides the location with a distributed setting that would make security and responsibility in the conventional world of digital forensics a nightmare. Cryptographic Distributed Ledger Technologies of Blockchain are based on the consensus technology, which allows aggregating, housing and authenticating digital evidences in a set of peer pairs in a secure way. As a result, the study that has been suggested in this paper, Blockchain Based Digital Forensic Architecture (BC-DFA) is founded on the distributed characteristics of blockchain, and is concerned with the decentralization and security of digital evidences. A combination of multiple essential methods including AOKGE: authentication with the best key generation encryption, SBVM: Secure Block Verification Mechanisms and implementing Multi-key Homomorphic Encryption or MHE is used to end up with the truly secure data encryption. The information and the secret key are spread in a manner that reduces the chances of single point failure that is associated with the centralized cloud design that reveals the information in the literal form and promotes hacking and unauthorized access. The SBVM authentication is done to authenticate all the data blocks in order to ease the tracing of any tampering or alteration of forensic evidence.
