Secure and Efficient Authentication Scheme in IoT Environments

Optimization of resource consumption and decreasing the response time authentication requests is an immense urgent requirement for supporting scalability resources in IoT environments. The existing research attempts to design lightweight protocols address these issues. However, schemes proposed literature are lacking creation a (i.e., low computing, communication, storage cost) secure architecture. devices approaches consume high electricity computing power, despite fact that have limited power capabilities. Furthermore, lead increase burden on memory also create heavy traffic communication channel, increasing device requests. To overcome limitations, we propose novel architecture uses crypto-modules, which optimize usage one-way hash functions, elliptic-curve cryptography, exclusive-or operation. We demonstrate scheme’s security strength using informal analysis verified it by considering widely used automated validation internet protocol application (AVISPA) ProVerif tool. result shows scheme effective against active passive attacks satisfies design. Moreover, calculate working cost implementing accepted standard pairing-based cryptography (PBC) library embedded devices. implementation proves reduces computation 0.933 ms, 1408 bits, 384 removes gaps.
