Trusted Data Interaction Technology Based on Alliance Chain

The current IP architecture is faced with scalability, security and dynamic problems, while the current DNS also has the problems of centralized management and server security. The defects of IP system make it unable to adapt to the current rapid development of business. In the current solution, the Content Centric Network (CCN) in the Information Centric Network (ICN) is considered to be able to better meet the needs of users. It takes the content as the center for data transmission, and uses the data itself to name, which completely changes the original network transmission system. Blockchain is a distributed platform in peer-to-peer network environment, in which multiple nodes participate and reach a consensus through a specific consistency algorithm. It has the characteristics of unforgeability, tamper proof and traceability, and carries trusted data and computing services. Alliance chain is a kind of blockchain, the characteristics of the alliance's blockchain, such as decentralization, non tampering, traceability, access mechanism, and information disclosure within the network, point out the direction for the realization of a new domain name system of co management and co governance.This paper gives full play to the trustworthiness and non tampering characteristics of blockchain technology, integrates the naming and addressing scheme based on alliance chain into Name Data Network(NDN) architecture, and proposes an open system of independent naming and marking and exchanging data content index in peer-to-peer network environment. This system uses OpenID to identify any data content object, and combines with cryptography technology to realize the trusted transmission of data in peer-to-peer network. Experiments show that the system designed in this paper has the functions of data index registration, update, cancellation and query, the efficiency is basically the same as the existing domain name system, and has stronger security.
