22865 该文提出一种基于拍卖方式的云计算虚拟资源分配和定价机制(VRAP)。 In this paper, a truthful auction mechanism is designed for Virtual Resource Allocation and Payment (VRAP) in cloud computing.
22866 这种机制的特点在于，用户在一次拍卖中可以提出多个资源需求。 In this mechanism, users can submit multiple requests at one time, but only one request can be satisfied, known as multi requirements single mind.
22867 证明了在这种机制下，资源提供商可以获得较以往拍卖机制更大的收益，同时能够保证用户出价是可信的。 It is proved that the resource providers can obtain more social welfare under this mechanism than before, and it can guarantee the users' bids are truthful. The mechanism is still compatible with the traditional auction which the user can only submit one request.
22868 进而在具体资源分配问题上，提出一种单调的启发式算法能够在很短时间内计算出分配结果，通过资源稀有度概念设计了再分配策略，可以保证云资源提供商的收益极大化； For the resource allocation problem, a heuristic algorithm is proposed to get the allocation result in a short time, through the reallocation strategy, the social welfare of the cloud resource provider can be maximized.
22869 在支付价格计算算法设计中，基于临界值理论计算支付价格，从而保证机制的公平可信。 The payment algorithm takes into account critical value to ensure that the machnism is truthful.
22870 在社会福利、执行时间、资源利用率等多个方面对 VRAP 进行了测试分析，取得了很好的效果。 In the experiment, it is analyzed in terms of social welfare, execution time, resource utilization and so on. Experimental results show that the proposed scheme has good effect for virtual resource action.
22871 属性基加密因其细粒度访问控制在云存储中得到广泛应用。 Attribute-Based Encryption (ABE) scheme is widely used in cloud storage, which can achieve fine-grained access control.
22872 但原始属性基加密方案存在密钥托管和属性撤销问题。 However, the original attribute-based encryption schemes have key escrow and attribute revocation problems.
22873 为解决上述问题，该文提出一种密文策略的属性基加密方案。 To solve these problems, this paper proposes a ciphertext-based ABE scheme.
22874 该方案中属性权威与中央控制通过安全两方计算技术构建无密钥托管密钥分发协议解决密钥托管问题。 In the scheme, the key escrow problem could be solved by escrow-free key issuing protocol, which is constructed using the secure two-party computation between the attribute authority and the central controller.
