Abstract

In some non-real time applications, data is collected by mobile sinks (MSs). This kind of network is vulnerable to MSs replicated attack. In this attack, replicated MSs can collect data from sensor nodes by establishing pairwise keys with them using keys information obtained from captured sensors. In this letter, a ( ${M}$ , ${m}$ ) authentication scheme against the attack is proposed. The analysis and simulation results indicate that the scheme can improve networks’ resilience against MS replicated attack as compared with existing schemes.
