【 摘 要 】

A wireless sensor network (WSN) is a wireless network containing of spatially distributed autonomous nodes utilising sensors to evaluate the physical or environmental circumstances. In several critical applications, an external user can directly monitor the real-time information from sensor nodes. In this case, before providing access, authenticity of the user is required to be proved by a suitable technique. Thus, in critical WSNs based real-time applications, authenticity of the users are very significant. Till now, many techniques have been developed to design a secure protocol for WSNs, to prevent unauthorised access. However, these techniques are vulnerable to wormhole attacks, which happen due to lesser synchronisation among the sensor nodes. Therefore, to handle this problem, an integrated modified-signature and recommendation-based trust evaluation protocol for WSNs is proposed. The extensive experiments have shown that the proposed technique outperforms over the available approaches.
