A Design of Secure Authentication Method Using Zero Knowledge Proof in Smart-Home Environment

As the IoT technology is being changed, diverse services are being developed. The smart home environment, which is the representative IoT technology, is facilitating the life more convenient and the smart home market is emerged rapidly while the IoT technologies are applied, but when authenticating in smart home network, the authentication should be made using the secret key of the node. In the smart home network environment, the more the nodes are increased, the more the burden of home gateway to manage the secret key of the nodes is increased. To solve this problem, this study suggests secure and efficient authentication technique through the zero-knowledge proof without using the secret key between the node and the home gateway.
