An Authentication Scheme for Internet of Things
Internet of Things (IoT) is changing traditional perceptions of the current Internet towards a vision of smart objects interacting with each other. However, security issues are the major obstacle for their deployment. Among these issues, authentication of the different interconnected entities and exchanged data confidentiality constitutes the main concerns for users. In this paper, we propose a new lightweight authentication scheme for an e-health application in Internet of Things. This scheme allows both of sensors and the Base Station (BS) to authenticate each other in order to secure the collection of health-related data. Our scheme uses nonces and Keyed-Hash message authentication (HMAC). In addition, it provides authentication, and it terminates with a session key agreement between each sensor and the Base Station. To assess our scheme, we carry out a security analysis. The obtained results show that our scheme is resistant against different types of attacks.
