Instruction reorganization method and device

Abstract

The invention provides an instruction recombining method in the operating process. The instruction recombining method includes the steps that step1, an instruction operating environment is cached; step2, a target address is read from a first storage position, a machine instruction segment to be dispatched is obtained according to the target address, and the last instruction of the machine instruction segment to be dispatched is a first jump instruction; step3, the target address of the first jump instruction is stored in the first storage position; step4, the first jump instruction is replaced by a second jump instruction to form a recombining instruction segment with a second address, and the second jump instruction points to an entry address of an instruction recombining platform; step5, the instruction operating environment is recovered, and execution is continued by jumping to the second address.

Description

technical field [0001] The invention relates to the field of computer security, in particular to an instruction recombination method and device. Background technique [0002] The existing field of electronic information security includes three sub-fields: system security, data security and equipment security. [0003] In the field of data security, the following three technologies are generally used to ensure data security: (1) Data content security technology, including data encryption and decryption technology and end-to-end data encryption technology, to ensure that the content of data is not illegally read during storage and transmission (2) Data security transfer technology, including preventing illegal copying, printing or other output, and ensuring the safety of data during use and transfer; (3) Network blocking technology, including network physical blocking and setting up network barriers, etc. . [0004] According to relevant analysis, the total effective detecti...

Problems solved by technology

The above-mentioned technologies are even more unable to prevent active or passive leakage of secrets by personnel involved in secrets. For example, insiders can carry storage devices, download required materials from internal networks or terminals and take away storage devices, resulting in internal leaks; Take the computing device with you directly

[0005] In summary, anti-copy technology cannot guarantee that confidential information will not be illegally stored on the terminal

Based on network filtering, it cannot ensure that confidential information is not lost

Confidential personnel may leak secrets through malicious code or malicious tools, and may also leak secrets due to loss of control of secret-related equipment or storage media
