This paper introduces the definition, characteristics of cloud computing and security problems in cloud environment, emphatically analyzes the trust evaluation of cloud users, introduces the basic concepts and principles of chord algorithm, and builds a cloud user trust model based on chord algorithm, which provides a solution for cloud users ' trust evaluation. The specific content includes: elaborated related concept, including cloud computing, chord algorithm and trust, direct trust, indirect trust, trust degree and so on, and studied the trust in the cloud computing environment related representation and the application, introduced the Cloud User trust level and the service level definition, proposed based on cloud user historical usage behavior, The direct trust of cloud service transaction amount and time decay factor, the indirect trust of adding weight factor and the definition of cloud user confidence established by neutral initial Trust make the evaluation of cloud User trust level more accurate. A cloud user trust model based on chord algorithm is established to evaluate cloud users, cloud service providers can provide corresponding level services according to Cloud users ' trust level, and establish a simulation environment to simulate the cloud User trust model based on chord algorithm, The validity and practicability of the trust model are obtained through the comparative analysis of the order search and chord search of cloud User Trust degree. The innovation of trust model based on chord algorithm is that the calculation of cloud User trust is more accurate while saving computation time, while adding some weight factors does not affect the efficiency of calculation, but the establishment of chord ring makes the query become more rapid and convenient. After some analysis on cloud User Trust model, this paper puts forward the cloud user trust model based on chord algorithm, uses chord algorithm to store and query Cloud users ' trust, improves the trust evaluation speed of cloud users, saves the network resources, and speeds up the time that cloud service providers identify cloud users ' trust level, Provides an effective solution to the problem of trust in cloud computing.
