A Survey on Encryption Algorithm with Hybrid Block Chain in Wireless Body Area Network

The recent electronic Medical monitoring system focuses on maintaining the database of patients with their medical history and up-to-date prescriptions and treatment maintained with high degree of confidentiality. The E-Medical services where Wireless Body Area Network (WBAN) is integrated face certain challenges such as data sharing, network reliability, database management and so on. The greatest threat in WBAN remained the data security and integrity. Several new methodologies supports to overcome these threats with secure hash function, digital signature with effective routing protocols to provide enhanced solutions for secure data maintenance and sharing in WBAN. The security system based on Block Chain Technology(BCT) are the most common trust building measure for WBAN, where the data are stored in distributed ledgers. This technology faces problems on minimal storage size and unauthorized access of the distributed data. This was overcome by the technique called sequential aggregate signature scheme with designated verifier with block chain based cloud transaction in WBAN in recent trends. The above scheme faces problem of wastage of storage space in the ledgers and it could be rectified by the proposed system of Encrypted Multi map block chain in WBAN which supports high degree of data access with reduced computational complexity of storage. This proposed system aims to simulate the WBAN with improved access of distributed authentication key of users in ledger pools and provides confidential sharing of data. This system deals with the comparative study of different encryption used in block chain storage to analyze their performance in WBAN
