Elliptic curve cryptography based key management and flexible authentication scheme for 5G wireless networks

Due to the technology development and need, the integration of WSN and 5G will be a key driver for successful IoT deployment. The Security issues are the major threat and challenge while integrating the WSN and 5G. Therefore here Elliptic Curve Cryptography (ECC) based flexible authentication and key management (EKAFAS) scheme is proposed in this paper to overcome the security vulnerabilities and to improve the system robustness of WSN in 5G integrated IoT. In order to provide the system with more secured, the ECC is employed for user's authentication and authorization. For the secured end to end communication user authentication and key agreement are essential. The sensors collect and process a large amount of personal information and it should be prevented from the adversaries that are able to access the private data. The secured system architecture for the integration of WSN and 5G for Internet of things is described by using the cryptanalysis algorithm. The system efficiency is determined for ECC based key agreement and flexible authentication scheme on basis of data transmission cost, computation cost, false positive rate and trust node rate. The proposed method is compared with the existing methods to measure the effectiveness.
