A hybrid key generation and a verification scheme dataset

By introducing high randomness with reduced computational cost, physical layer (PHY) key generation is one of the candidate tools which can be used for the security of the Internet of Things (IoT) applications. Non-identical secret keys are one of the main problems of the physical layer (PHY) key generation schemes. In order to address this problem, key verification schemes which are based on information reconciliation are used. In the current key verification techniques, the legitimate nodes reveal some information related to their secret keys in order to eliminate non-identical bits. In this work, by jointly using PHY key generation with an embedded key, we propose a hybrid key generation and key verification scheme, where the revealed information during the key verification process is negligible, and the verified keys are identical. Numerical results and software-defined radio based tests show that the proposed verification scheme achieves the requirements of the Internet of Industrial Things (IIoT) systems.
