Problems solved by technology
However, existing cloud computing applications still lack a distributed policy-driven access control mechanism, so it is necessary to provide a distributed execution method for privacy policies to solve the problem of cloud-based implementation of privacy policies
In addition, since the privacy policy is also stored and executed in the "cloud", the attacker may still pretend to be the user to tamper with the privacy policy, that is, it is difficult for the user to know whether the cloud service provider faithfully abides by the policy

Embodiment Construction
[0032] The operating environment of the present invention is composed of two parts, a remote access client program and a cloud platform. Among them, the remote access client program is developed based on Myeclipse10.0, which is implemented in J2SDK1.6 version java language, installed on the Windows7 system configured as Intel Core Duo.i5-4200H@1.7GHz, and used to send user requests and accept Service response; the cloud platform is developed based on the Swift1.7 cloud storage architecture. The platform is composed of 9 IntelXeon E5-2650@2.0GHz Linux system servers configured with a trusted root TPM. Each module in the privacy policy distributed execution method It is independently configured on each server, and based on the trusted root TPM in each server, the implementation of the privacy policy can be guaranteed, and the third-party Sunxacml development kit is used to analyze and supplement user requests, subject and object metadata, and privacy policies. Full sum matching ...

The invention discloses a credible execution method for a privacy policy in a cloud environment, and particularly relates to credible access control for cloud data privacy protection in the cloud environment, which aims to solve the problems of implementation and implementation guarantee of the privacy policy in the cloud environment in the technical field of cloud computing security. The method adopts a policy-driven concept; according to various privacy protection requirements of multi-tenant, flexible privacy protection is realized through distributed execution of the privacy policy in the cloud environment; furthermore, through combination of credible computing technology, the cloud privacy policy is protected from malicious modification by attackers, credibility of execution of the privacy policy is guaranteed, and finally, privacy security of cloud data storage of the user is guaranteed.
Description
technical field [0001] The invention belongs to the technical field of cloud computing security, and in particular relates to a trusted access control method for cloud data privacy protection in a cloud environment. This method adopts policy-driven thinking and trusted computing technology, and provides a distributed execution method of cloud privacy policy (privacy protection-oriented access control policy) and its implementation guarantee method, so as to realize the trusted execution of cloud privacy policy. Background technique [0002] Cloud computing is a computing model and business model based on the Internet that gathers various IT resources scattered to form a shared resource pool and provides users with large-scale computing and storage services in a dynamic and flexible manner. hot spots in technology. However, in the cloud environment, user data is stored in the "cloud", and these user data may involve sensitive information of user privacy. Since the rise of c...
