Remote Attestation on Trusted Cloud Computing

In the cloud computing mode TCCP, there exist shortcomings of overburdened trusted TC, the anonymity of nodes and configuration information of platform can’t be guaranteed. In this paper, we propose an anonymous scheme based on attribute certificate. The scheme is achieved by the trusted ring signature based on attribute certificate. By the security analysis, the anonymity and platform configuration information of computing nodes is guaranteed. By simulation experiment, we obtain the efficiency of the scheme. Comparing with Boneh ring signature based on ECC algorithm, this scheme has a great superiority in terms of large amount of ring signatures.

A Research on the Enterprises Information Management Based on E-Commerce

The so-called e-commerce refers to the ESD (Electronic System of Distribution) which can be achieved in the areas of enterprises through the modern network and information technology, including the issuance and exchange basic information of the network, enterprises promotion, pre-market advertising, after-sales service and electronic distribution by electronic means, as well as, internal process and the electronic management information system applications of enterprises. In order to accommodate the complex network data of large scale companies, this thesis analyses PMI, strategy and role hierarchical model. On such a basis, the thesis proposes an applicable plan for access control of enterprises information system based on attribute certificate. These new entrants are often backed by advanced technology companies and competitive organizations with funds from Chinese and foreign conglomerates. Therefore, the applications of e-commerce in the field have brought about the information of business operations and internal management, which can provide consumers with a higher quality of services. In this paper, the enterprises information management and organization will be discussed in the e-commerce. Currently the technology of information and network develops rapidly. As a result, e-commerce, e-government and e-office prevail over our society and have become a part of our life. This situation enhances the efficiency of work and changes for the enterprises information management in China.
