In order to protect the security of cloud entities and better practice cloud’s objectives of providing low-cost and on-demand services, this paper proposes a novel cloud trust transaction framework and also a new trust fuzzy comprehensive evaluation based cloud service discovery algorithm. The new algorithm uses trust multi-dimensional vector to represent the credibility of providers when offer different types of services and applies fuzzy comprehensive evaluation method to classify services. The simulation experiments show that the proposed algorithm ensures relatively high trust accuracy. Besides it has certain advantages in rejecting malicious nodes and improving the transactions ’ success rate compared to other kindred solutions.
