ECC-based lightweight authentication and access control scheme for IoT E-healthcare

The E-healthcare system has a complex architecture, diverse business types, and sensitive data security. To meet the secure communication access control requirements in user–medical server, user–patient, patient–medical other scenarios system, efficient authenticated key agreement authorization scheme need to be studied. However, existing multi-server solutions do not consider authentication of Wireless Body Area Network (WBAN) are suitable for server scenarios; most WBAN schemes single-server type, which difficult applications, study user–patient real-time received due attention. This work first reveals structural flaws security vulnerabilities typical then proposes an architecture multiple with separate management designs novel ECC-based multi-factor remote using physically unclonable function (PUF) hash. Security analysis efficiency show that new achieved improved functionality higher while maintaining low computational overhead.
