Information security big-data resource access control system based on cloud computing and credible computing

The invention discloses an information security big-data resource access control system based on cloud computing and credible computing. The system architecture is that a credibility access mechanism and a credible relationship transmission mechanism are constructed based on the characteristics, such as protective functions, authentication and integrity measurement; therefore, a credible chain from data storage, information security management to information security access is established; and the information security big-data resource access control system comprises a cloud storage service module 10, an information security management module 20, a big-data service module 30, a credibility-based key generation module 40, a credibility-based encryption module 50, a credibility-based decryption module 60 and a user access module 70. According to the information security big-data resource access control system disclosed by the invention, on the basis of credible computing and cloud computing technologies, the information security management module 20, the credibility-based key generation module 40, the credibility-based encryption module 50 and the credibility-based decryption module 60 are designed; therefore, rapid security access of information security big-data resources is realized; and the security and the credibility of the system are improved.
