Abstract

The invention relates to the field of data processing, in particular to a data controllable circulation method supporting access control, which comprises the following steps of: initializing a system by a certificate issuing terminal; the attribute authorization terminal, the data owner terminal and the data user terminal are respectively registered in the certificate issuing terminal to authenticate identities and attributes; the data owner terminal encrypts the data; the data user terminal performs data access; the data user terminal carries out data decryption; the attribute authorization terminal and the certificate issuing terminal complete attribute revocation of the data user terminal; the data trusted storage and controllable circulation method supporting access control solves the problem of data leakage and realizes controllable circulation of ciphertext data.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a data controllable flow method, system, device and medium supporting access control. Background technique [0002] Since most organizations exist in isolation from each other, they store and maintain data independently, forming data islands, which is not only detrimental to the development of the industry, but also causes waste of storage space resources and duplication of data resources. In today's era of cloud computing and big data, Data sharing is the best way to maximize the value of data, and secure data sharing between different organizations is very necessary. [0003] In order to maximize the value of data, it is an inevitable trend to share data between different organizations and related derivative entities. With the rapid development of emerging information technologies such as big data, cloud computing, and mobile Internet, the safe storage and controllable sharing o...
