An Improved Authentication and Security on Efficient Generalized Group Key Agreement Using Hyper Elliptic Curve Based Public Key Cryptography for IoT Health Care System.

Due to tremendous development in the network technologies forms an Internet of Things (IoT) based Health Care System (HCS) is an essential application in day-today life. In HCS, constitute a group communication among doctors, patient, caretaker, ambulance, and hospital, which intern's devices transfer personal information from one to many group members. Providing security on the personal health information is the most critical issue, because malicious access on this information may leads to life threads. Concurrently, traditional cryptographic framework has unsuccessful to protection to the HCS over lightweight communications network. So, the proposed framework deals the security flaws through hyper elliptic curve based public key cryptosystem, which combines Digital Signature algorithm, Elgamal approaches that ensure the entity authentication and secure group communication. The performance of the proposed work analyzed using efficient security measures and compared with related schemes.
