Anonymous chaotic cloud storage strategy based on Cp_abe and two-fork tree bias codes

Hebei University Yi Qingqing

With the application and development of cloud computing technology, cloud storage and its security, as its basic component, have become the focus of current research. Cloud storage is a new concept that extends and develops in the concept of cloud computing (cloud computing), which means that a large number of different types of storage devices in the network can be assembled together through application software through the functions of cluster application, grid technology or Distributed File system, A system that provides data storage and business access functions together externally. The emergence of cloud storage, so that users abandon the previous storage mode, without the purchase of large hardware cluster resources and complex management costs under the premise to meet the needs of data storage. However, under the current technical conditions, cloud storage still has security problems such as data security and confidentiality, which is a problem that must be solved in the development of cloud storage. According to the problem of data sharing and confidentiality in cloud storage, an anonymous cloud storage strategy based on attribute is proposed MACSS (ListBox encryption Anonymous Cloud Storage). The confidentiality and integrality of the data in the cloud storage platform are ensured by the mechanism of cipher access control and data anonymous scrambling storage. In real-world applications, users cannot fully trust the data security measures provided by cloud storage service providers, so MACSS uses modern cryptography and attribute-based key management to encrypt management and access control of user data. Establish a cloud access control model, using symmetric asymmetric encryption algorithm to encrypt plaintext data, using attribute based Cp_abe algorithm to establish access control system, to realize multi-user sharing of data, and to store data by means of binary tree coding and anonymous chaotic storage, and in untrusted cloud storage environment, Secure storage of data. Finally, the security analysis and comparative analysis of MACSS are carried out to illustrate the feasibility of the model.
