On the third day of the Fifth Cloud Computing Conference, Zhang Huanguo, Professor of School of Computer Science, Wuhan University, delivered a keynote speech titled "Building Trustworthy Cloud Computing - Cloud Computing from the Banks' Perspective" on the thematic forum of Cloud Computing Security. Taking the banking industry as an example, he introduced the security issues and technical development ideas facing cloud computing in special industries from several aspects, including security issues of cloud computing, trusted computing, several key technologies for building trusted cloud computing, and examples of building trusted cloud computing. He believes that cloud computing system is also a kind of information system, so there is a ****ual security problem that exists in information systems in general. Since the cloud computing system is a new type of information system, there are also some new security problems in cloud computing, which means that cloud computing has its own special security problems. The individuality problems of cloud computing security include the problems of ****ization of equipment resources, non-self-identity of data storage and processing, and so on. He proposed the concept of trusted computing, which aims to improve the trustworthiness of computer systems. According to him, a trusted computing system is a computer system that can provide system reliability, availability, and security. Commonly speaking, trusted ≈ reliable + security. China started not too late in the field of trusted computing, the level is not low, the results are promising, and it has stood in the forefront of the international trusted computing field. A small climax of trusted computing will be formed in the period starting from 2013. This small climax stage to expand the application of trusted computing as the main feature.
