Abstract

The invention discloses an attribute-based encryption method and system. The application encrypts shared files before file sharing, and the encryption method involves attribute sets corresponding to users who are allowed to access shared files. The purpose is to realize that only users who are allowed to access shared files Users can successfully decrypt the ciphertext, which greatly reduces the risk of information leakage.

Description

technical field [0001] The invention relates to the field of information encryption, in particular to an attribute-based encryption method and system. Background technique [0002] With the rapid development and popularization of the Internet, more and more sensitive information is stored and shared on third-party Internet sites (such as cloud storage). Currently, these sensitive information are not stored in encrypted form on cloud storage, so they face the risk of sensitive information leakage, and the security threats caused by information leakage are also increasing. [0003] Therefore, how to provide a solution for encrypting sensitive information before sharing is a problem that those skilled in the art need to solve at present. Contents of the invention [0004] The object of the present invention is to provide an attribute-based encryption method and system, which encrypts shared files before file sharing, and the encryption method involves the corresponding attri...
