In today’s rapid development of information technology, people on informationtransmission and storage technologies demand increases. Centralized storagetechnologies exist capacity is small, poor scalability, cost issues, and P2P-baseddistributed storage technology has centralized storage technologies do not have theadvantage of being able to meet the growing storage needs. However, there are securityrisks P2P storage system, how to storage capacity and speed to meet the people on thebasis of improved storage security is crucial. Although the authentication data structurecan be a good way to solve the centralized storage of data security authenticationproblem, but not a good solution to the security of the data stored in the distributedauthentication issues. Distributed authentication jump table (DASL) and distributedmerkle tree (DMT) can solve distributed storage environment data authenticationproblem, but there are some security risks and the relatively high cost and other issues.In this study, the P2P distributed storage certification status of research on the basis ofcombing, respectively, from the P2P network and storage authentication technology,distributed authentication B-tree, a P2P DHT-oriented data authentication model, aP2P DHT-oriented distributed storage authentication module implementation, andseveral other aspects of the research. The innovation of this study: First, a distributedauthentication B-tree (Distributed Authenticated B Tree, DABT) specific programs andintroduced the related design ideas, algorithms, as well as DABT related aspects areanalyzed and evaluated. Secondly, DABT application model P2P storage system beingused, and designed to achieve a P2P DHT-oriented prototype of distributed storagecertification, to ensure file integrity and authenticity aspects of the test, and furtheramended the related issues.
