Research Of Object Name Service And Its Security

Internet of Things is one of the emerging technologies in recent years. Itimproves supply chain operations, and asset tracking area. The pressures of Internetof Things will concentrate in the backend Articles coding analytical server. In theprocessing of EPC resolution, if the ONS resolver speed is not fast enough, or theresult is not accurate, thus will hinder the application and promotion of the Internetof Things. At present, the research of ONS architecture is still in exploratory stage.This thesis mainly focuses on the research of ONS architecture.Kademlia is one of the typical protocols among DHT. These theses propose animproved ID self-Adaptive method-LKad, to resolve the disadvantage of huge IDspace and node distribution sparse of Kademlia protocol. LKad has regular abilityof self-adaption to the length of network and able to working on a relativelycompact space. It not only release the question caused by the sparse distribution ofnodes, but also promotion the query efficiency of node and document. Applyimproved LKad protocol in the new ONS frame can form a hierarchical, distributedONS query architecture.Via comparative analysis of existing DNS security issues, combined with thecurrent Internet security measures, such as PKI and SSL. This thesis also proposesONS security frame aim to the front ONS distribution architecture, and can bettersolve the security problem that ONS may face with. Has security ONS architectureand flexible caching mechanism that can greatly promotion the analyticalefficiency.
