Abstract:

The development of enterprise informatization brings new challenges to the secure files management,but traditional file security management schemes only pay attention to the file security and ignore the identity authentication for the person who uses the file.Based on identity authentication and file encryption technology,a lightweight file secure management scheme is proposed to meet the demands of file storage protection for small and middle enterprise.The scheme has been proved to be able to offer secure,efficient storage and usage through detailed analyses of security and performance.
