Abstract

The invention discloses a system and a method for verifying a file code signature. The system comprises a user signing module and a signature verifying module, and the user signing module is connected with the signature verifying module in a communication way. The system is characterized in that the signature verifying module comprises a verification processing module and a public key processing module; the verification processing module is connected with the user signing module and the public key processing module in the communication way respectively; the verification processing module is used for controlling to execute verification of a signature value; and the public key processing module is used for controlling to process a trust public key. The method for verifying the file code signature compares a complete summary value with a decrypting complete summary value and confirms whether to execute a mode of a file program according to the comparison result so as to effectively prevent virus programs and Trojan-horse programs entering, ensure the absolute safety of file programs, and improve verifying efficiency and operation flexibility at the same time.

Description

technical field [0001] The technology of the invention is a verification system and its method, in particular to a file code signature verification system and its method. Background technique [0002] With the continuous development of computer operating systems, the types of computer operating systems have been diversified, but their security is also subject to more and more challenges. Many executable file formats have become targets of attacks by viruses and various malicious codes. For example, many virus programs under the computer operating system realize intrusion by directly modifying file programs. The traditional computer operating system does not check the integrity and legality of the executed code, thus allowing many virus programs and Trojan horse programs to take advantage of it. [0003] Code signature verification is an effective method to prevent viruses and other malicious codes from invading. For the code signature verification method under the compute...
