Abstract

The invention provides a protection method and device for executable files. According to the method, an executable program to be protected is written in a common region of a USB flash drive encryption lock; when clicked, the encrypted executable program in the common region is decrypted by a monitoring actuator placed in a CD-ROM region of the USB flash drive encryption lock or by an encryption and decryption part of the USB flash drive encryption lock; the monitoring actuator starts the program to be started by means of a debugger. The method has the advantages that decryption of the encrypted program depends on the USB flash drive encryption lock, the efficiency of executing the program is unaffected, data leak caused by the program being copied can be prevented, operation by means of the debugger is performed, debugging and cracking are more difficult, and safety is improved.

Description

technical field [0001] The invention relates to the field of information security, in particular to a method and device for protecting executable files. Background technique [0002] U disk (USB Flash Disk), the full name of USB flash drive. It is a miniature high-capacity mobile storage product that uses a USB interface and does not require a physical drive. It is connected to a computer through a USB interface to achieve plug and play. Because the U disk has the characteristics of small and exquisite, easy to carry, large storage capacity, fast speed, and small size, it is more and more widely used in daily life and work. [0003] Ordinary U disk is a transparent mobile storage media device, there is no access control for data access, as long as the access party with USB interface can use it without hindrance. Therefore U-disk brings convenience to people, but also brings an important problem: information leakage. [0004] The reasons for U disk information leakage main...
