A Reverse Sequence Hash Chain-based Access Control for a Smart Home System
2020
As a smart home system utilizes a machine learning technology, intelligent and user-friendly smart home systems will be trends more and more. However, since a consumer home generally consists of various IoT-devices which are with different capabilities and from different vendors each other, it is difficult to apply centralized high performance security solutions to their smart home systems. A blockchain system, a decentralized authentication solution, is spotlighted as an alternative. However, since a blockchain system needs high resources for its mining process, to apply a blockchain technology to a smart home system, it is needed to improve such a high resource problem. This paper presents a reverse sequence hash chain based authentication scheme for a smart home. Since this authentication system needs small numbers of hash value computation to compute the solution of POW, a user can build a authentication system of his smart home without using a centralized and heavy security system like PKI.
