Real-time encryption and decryption system and real-time encryption and decryption method for mobile products

Abstract

The invention relates to a real-time encryption and decryption system and a real-time encryption and decryption method for mobile products. When a mobile terminal is in an encryption mode, any file data operation refers to downloading encrypted data from a server side and authorizing the mobile terminal to decrypt the encrypted data to display to a user in a clear text mode, and any user operation result is stored in the server side after being encrypted; after the user quits the encryption mode, the mobile terminal cannot contact with the encrypted data, the user enters a common mode, and operation data are stored in the mobile terminal at the moment. According to the real-time encryption and decryption system and the real-time encryption and decryption method, existing operation modes and use habits of the user are not changed, input and output data quantity is not increased, and high safety is achieved.

Description

technical field [0001] The invention relates to the field of data security, in particular to a real-time encryption and decryption system and method for mobile products. Background technique [0002] Mobile products such as mobile phones have become an indispensable part of our lives. With the rapid development of hardware, software and networks, mobile products will become more powerful and inevitably face threats to information security. [0003] At present, the main encryption methods used by mobile products such as mobile phones are: suffix name encryption, shift method, setting hidden attributes, mobile phone lock encryption, encryption software (Phone Wizard encryption, etc.) to encrypt files. [0004] It can be seen that the basic idea of ​​several encryption methods currently used by mobile phones is still the traditional "prevention and blocking" mode, and its main disadvantages are twofold: [0005] 1) The security is not high. At present, several encryption meth...

AI Technical Summary

Problems solved by technology

In fact, these methods are relatively simple at present, and are acceptable to general users at present, but for customers with relatively high security requirements, or with the further popularization of mobile phone functionality, these methods will not be able to meet our security requirements

[0006] 2) The operation is complicated, resulting in additional input and output data volume and low efficiency

This technology performs real-time processing of data encryption and decryption requirements in the user's normal artifacts, without explicit encryption and decryption processes, and does not generate temporary files
