One of the most recent challenges in communication system and network system is the privacy and security of information and communication session. Blockchain is one of technologies that use in sensing application in different important environments such as healthcare. In healthcare the patient privacy should be protected use high security system. Key agreement protocol based on lattice ensure the authentication and high protection against different types of attack especially impersonation and man in the middle attack where the latticebased protocol is quantum-withstand protocol. Proposed improved framework using lattice based key agreement protocol for application of block chain, with security analysis of many literatures that proposed different protocols has been presented with comparative study. The resultant new framework based on lattice overcome the latency limitation of block chain in the old framework and lowered the computation cost that depend on Elliptic curve Diffie-Hellman. Also, it ensures high privacy and protection of patient’s information.
