Embodiment Construction

[0027] Cloud computing offers many advantages over traditional models, such as information sharing in a virtual environment, dynamic scalability, virtualization of software, platforms, and storage, and so on. However, in addition to the many benefits that cloud computing has brought to people, many problems have arisen, such as: performance issues, fault tolerance, interoperability, data migration and conversion from legacy systems, etc. The main problem is security, such as virtualization Security, application security, identity management, privacy security, among which the most worrying and important thing is user privacy security. The above security issues prompted us to propose a reliable cloud user data protection scheme based on privacy level classification and hybrid encryption to ensure that the privacy of users on the cloud platform is not violated.

[0028] In cloud computing, data is destined to be stored in the cloud in the form of ciphertext, which is the most bas...

Abstract

The invention provides a user privacy protection method based on attribute and homomorphic hybrid encryption in the cloud environment, and is mainly used to solve the security problem of user privacy in the cloud environment. First, the user sends his information to the cloud service provider, and the cloud service provider classifies the user privacy. Secondly, users use different encryption methods for different categories, namely homomorphic encryption and attribute-based encryption. Users use homomorphic encryption to ensure that important private information is more difficult to leak or be stolen, and users can perform calculations on their own private information; use attribute-based encryption to ensure that certain network resources are shared with other users. Finally, the user downloads the ciphertext for decryption. Through this hybrid encryption method, the security of user data privacy is further guaranteed. At the same time, it is convenient for users to operate their own important business data. In addition, the efficiency of encryption and decryption has also been improved to a certain extent.

Description

technical field [0001] The present invention provides a user privacy protection scheme based on attribute and homomorphic hybrid encryption in the cloud environment, which is mainly used to solve the security problem of user privacy in the cloud environment. The category of uses homomorphic encryption or attribute-based encryption encryption. At the same time, the user's encrypted data is managed and maintained in a unified manner in the cloud, which belongs to the field of cloud computing security. Background technique [0002] Cloud computing is another major Internet computing model proposed in the computer field after grid computing and distributed computing. Cloud computing can be divided into three service models: IaaS (Infrastructure-as-a-service, infrastructure as a service), consumption Users can obtain services from a complete computer infrastructure through the Internet; PaaS (Platform-as-a-Service, Platform as a Service), Paas actually refers to the platform for...
