Symmetric key-based authentication and the session key agreement scheme in IoT environment

Abstract

In this paper, the inter-device authentication and session key distribution system for the device with the encryption module only. In the proposed system, unlike the existing sensor network environment where the key distribution center distributes the key, each sensor node agrees with generation of session keys. In the proposed scheme, the performance is improved so that the authenticated device can calculate the session key in advance. The proposed mutual authentication and session key distribution system can respond against replay attacks, man-in-the-middle attacks and wiretapped secret key attacks.
