System and method for carrying out transparent encryption and decryption on file in intelligent mobile terminal

Abstract

The invention relates to the filed of mobile internet application safety in information safety, and discloses a system and method for carrying out transparent encryption and decryption on a file in an intelligent mobile terminal. The problem that a traditional encryption and decryption scheme is not high in safety and complex to operate is solved. According to the method, when a user requests to have access to the privacy file of the mobile terminal, mutual identity authentication is carried out between the mobile terminal and an intelligent bracelet at first, then a conversation secret key is generated through consultation, a data protection secret key sent by the intelligent bracelet is obtained after authentication succeeds, the protection secret key is set to a read-write filtering driving module of a virtual protection magnetic disc after the virtual protection magnetic disc is mounted, corresponding operations are carried out on the virtual magnetic disc according to the specific request type of the user, and therefore the scheme that transparent encryption and decryption are carried out on the file in the intelligent mobile terminal on the basis of intelligent bracelet authentication is achieved. The system and method for carrying out transparent encryption and decryption on the file in the intelligent mobile terminal are applicable to access control over the file in the mobile terminal.

Description

technical field [0001] The present invention relates to the field of mobile Internet application security in information security, and specifically relates to a system and method for transparently encrypting and decrypting files in an intelligent mobile terminal based on a smart bracelet-based security authentication and secret key trusteeship technology. Background technique [0002] With the rapid development of mobile Internet technology, mobile terminals have entered the era of intelligence, such as smart phones and tablet computers. Due to the convenience of mobile smart terminals, you can take photos, share, and even conduct financial management and office business at any time. Therefore, smart mobile terminals carry more and more personal privacy information, such as private photos and various private files. Once the mobile terminal is lost, a large amount of private information may be leaked. At the same time, when users use mobile smart terminals to surf the Intern...
