Method for Heterogeneous Identification Peer-to-peer Resolution Technology of IoT Based on Block Chain

Abstract

In IoT-related technologies, because of the lack of a unified standard, there are various identity types and coexist of many resolution services which cannot interconnect with each other, prone to single-point failure, single point of control and so on, cannot make full use of IoT resources, limiting the rapid development of the IoT. In order to solve the above problems, many scholars put forward solutions of decomposing the single resolution service into multi-root, and design new identity resolution to solve the heterogeneous identification. However, these solutions ignored the fundamental problem of data synchronization between nodes due to architecture change. This paper explores a peer-to-peer resolution service architecture based on block chain, makes full use of its consensus mechanism and trust feature to ensure the consistency of Common Mapping Table, and design the heterogeneous identity peer-to-peer resolution service. At last, through the experimental data of consistency conflicting indicators, the peer-to-peer resolution service based on block chain can effectively solve the problem of data consistency in distributed architecture, guarantee the correctness of data.
