CKMIB: Construction of Key Agreement Protocol for Cloud Medical Infrastructure Using Blockchain

In the traditional medical healthcare system, each facility is responsible for preserving its own records. Sharing such records with another establishment difficult them. To tackle this challenge, system leverages internet technology to transform into a modern electronic system. systems, managing security and privacy of patient data becomes major issue. As an alternative, sector might use blockchain exchange digitised data. Blockchain characterised by anonymity, decentralisation, immutability. It hard keep all on due expense volume. Cloud computing best solution storing type resolving problems like these. address these concerns, we offer blockchain-based key agreement protocol cloud network systems that enhances security. We demonstrate formal informal analysis proposed shows both secure communicative. provide verification using AVISPA software tool against man in middle attack replay attack. Finally, compute computation communication costs other existing protocols, has less than protocols
