A Transparent Encryption and Decryption Method Based on Intelligent Dynamic Driver Layer

Abstract

The invention relates to an intelligent dynamic driving layer-based transparent encryption and decryption method. The method comprises the following steps of transmitting IRPs to different processing logics through filtering different IRPs by utilizing a driving encryption technology; and determining whether generated handles need to be decrypted or not during reading / writing according to IRP request results in the different processing logics, recording a determination result in a memory, and maintaining a current handle list. The method has the following multiple advantages: 1, security storage and use of information data are completely realized and information is prevented from being associated with secrets, so that the problem that cannot be solved by a security product in the past is solved; 2, the user time is saved and the purpose of protecting files is achieved; and 3, manual encryption and decryption operations of users are not needed, and the encryption mode does not influence file opening time and file sizes, thereby effectively ensuring normal running of the files.

Description

technical field [0001] The invention relates to the field of data security, in particular to a transparent encryption and decryption method based on an intelligent dynamic drive layer. Background technique [0002] Nowadays, threats to the security of computer systems come from many aspects, and the losses brought by hackers and Trojan horses to enterprises are incalculable. Statistics show that the economic losses caused by network leaks in my country are as high as tens of billions every year. [0003] With the continuous development of information technology, the double-edged sword of network resources has become increasingly prominent. Security threats from the network are becoming more and more serious, such as network data theft, hacker attacks, virus releases, and even system internal leaks, which have made information security the primary issue in the information construction of various industries. [0004] According to the person in charge of the national security...

Problems solved by technology

At present, there are many security products with transparent encryption and decryption on the market that have realized the protection of digital content, but there are various deficiencies and defects: 1. Low safety factor; most products use the encryption and decryption in the user state of the operating system Operation, this method has low security, which will cause the digital content to "land in plaintext" during use, that is, the situation where the plaintext content is stored on the disk, which may easily cause confidentiality and leakage of confidential information; 2. Slow speed; The encryption and decryption operations completed in the user state are time-consuming and labor-intensive manual operations, which require careful handling by the user, resulting in insufficient file processing efficiency, and even have a certain impact on the file itself
