Blockchain-Enabled Secure Communication for Intelligent Digital Evidence Management Systems

Abstract

Most existing systems have sufficient data integrity but lack appropriate communication and decision-making methods that allow for timely responses to change. This paper discusses the use of a blockchain-based design as a method for overcoming these limitations by utilizing secure communication protocols and smart evidence management to support electronic evidence. An architecture based on multi-layers is constructed on top of blockchain, cryptographic encoding, hybrid storage (blockchain + IPFS) and a reinforcement learning-based adaptive component. The system is experimentally tested on both simulated and real-world digital evidence sets in different network loads, and attack conditions. The use of metrics like integrity accuracy, communication reliability, latency and scalability is used to measure performance. The proposed framework has high integrity preservation (>99%), enhanced the reliability of communications, and less latency as compared to baseline systems. The hybrid architecture can be used successfully to reduce the storage overheads.
