CUIAS - A User Identity Authentication Service for Discovery Service

摘要: Discovery service (DS) is designed to serve the following lookup function: Given RFID identifier of an object, it returns a list Internet addresses servers about this object across supply chain, which offer detailed information it. The stored in DS commercially sensitive, can reveal flow patterns, trading relationships or inventory levels, etc. Therefore must authenticate user's identity first before user allowed access DS. However, no authentication schemes satisfying actual requirements have been proposed until now. So paper focuses on problem and presents Centralized User Identity Authentication Service (CUIAS) based SAML PKI for DS, deployed as DHT network, offering excellent performance scalability. Through CUIAS, once authenticated, then many times certain period, not only simplifies process but also reduces resource cost. To ensure data availability confidentiality original split into multiple smaller blocks using Information Dispersal Algorithm (IDA) they are scattered within CUIAS. By analysis evaluation, CUIAS satisfy reliable secure service.
