Research Area:  Wireless Sensor Networks
The integration of the wireless sensor networks (WSNs) and the advanced 5G networks has greatly enriched applications of the Internet of Things. However, the open access to sensor nodes whose resources are limited makes the entire WSNs potentially insecure. It is impending to authenticate the identities of the communication participants to prevent various attacks such as eavesdropping, capturing, and tampering. Recently, an authentication and key exchange protocol for 5G-integrated WSNs was proposed by Shin et al. However, we have found that the scheme cannot defend against offline password guessing attacks and de-synchronization attacks. Therefore, we put forward an enhanced authentication and key exchange protocol, which can resist known attacks and shows more fitness for the scenario of 5G-integrated WSNs. In addition, we have analyzed that our scheme is provably secure under the random oracle model with a strict adversarial hypothesis and possesses a better performance than Shin et als scheme.
