中文摘要： 本项目针对云计算环境下的服务组合问题，研究一种面向个性化需求的可信服务组合新方法，提出保障服务组合可靠运行的优化策略。通过设计基于信任演化和偏好需求的可靠服务选择方法，探索满足个性化需求的服务调度机制，抑制合谋欺骗和恶意信任传播对服务选择的影响；同时提出基于安全协商和良好结果反馈的服务访问控制策略，研究辨识服务消费者非可信行为的有效方法，防止云计算中的服务资源被滥用；在此基础上设计服务组合全链路安全的可信度评价策略，从而构建满足个性化需求的可信服务组合方法，提高服务组合的安全性和灵活性。通过研究服务组合执行出错后的失效恢复和流程重构，建立服务组合运行的安全保障机制，增强组合服务运行的可靠性。通过仿真实验和电子商务中的在线实验，探讨组合方法的有效性和泛化性，本项目的研究将为云计算中的可信服务组合提供一种有效的新方法，对推动云计算环境下服务组合理论和技术的发展具有重要的科学意义和应用价值。

英文摘要： For the problem of services composition in cloud computing environment, a new method of trusted services composition oriented individual requirements will be studied in the project, and optimization strategy which guarantees reliable execution of services composition will be proposed. Through designing reliable service selection method based on trust evolution and preference requirement, the service scheduling mechanism satisfied individual requirements will be probed to restrain the influence on service selection caused by conspiracy fraud and malicious trust spread. Meanwhile, an access control strategy based on safety consultation and good result feedback will be proposed, and effective method for identifying the incredible behaviors of service consumer will be studied to prevent service resource from being abused in cloud computing environment. On that basis, a method of reliability evaluation of services composition for all link's safety will be designed, thereby the strategy of trusted services composition satisfied individual requirements will be constructed to enhance the safety and flexibility of services composition. Through researching the failure recovery after operation mistakes of services composition and process construction, a safety guarantee mechanism for composing services execution will be es
