A security protocol for D2D communications in 5G networks using elliptic curve cryptography

Advancements in the field of wireless and mobile communication motivate academia, industry, standardisation organisations to explore new technologies improve overall efficiency, spectrum utilisation, power consumption, security. One most essential proposed for short-range communications, which will play a key role 5G networks, is device-to-device (D2D) communications. D2D enables direct between two devices when they are close proximity without requiring help fixed infrastructure like base stations. Despite significant benefits provided by this networking paradigm introduces unique security threats services that should be solved order limit any malicious attacks. Towards end, paper, we focus on secure communications propose protocol establishing using elliptic curve cryptography. The utilises: (i) specific Mobile Identifiers acquired from hardware phone (i.e. IMEI) SIM card IMSI, MSISDN) operator (ii) storage saving private keys or signature data. verified validated with Scyther tool, performance evaluated terms resiliency analysis.
