Title (EN) VIRUS SIGNATURE MATCHING METHOD AND APPARATUS
(FR) PROCÉDÉ ET APPAREIL DE MISE EN CORRESPONDANCE DE SIGNATURES DE VIRUS
Abstract:
(EN) A virus signature matching method, including: obtaining an inputted target file (SI 02); loading a virus signature database, and successively extracting signature function identifiers from the virus signature database, the virus signature database comprising the signature function identifiers and virus signature type identifiers corresponding to the signature function identifiers (SI 04); obtaining signature functions corresponding to the signature function identifiers, and checking the target file by invoking the signature functions, to obtain corresponding check results (SI 06); and obtaining a virus signature type identifier corresponding to the target file according to the check results (S108). In addition, a virus signature matching apparatus is further provided. The foregoing virus signature matching method and apparatus can improve virus scanning and removing efficiency.
(FR) L'invention a trait à un procédé de mise en correspondance de signatures de virus, comprenant : l'obtention d'un fichier cible entré (S102) ; le chargement d'une base de données de signatures de virus et l'extraction successive d'identifiants de fonctions de signatures provenant de cette base de données, ladite base de données de signatures de virus comportant les identifiants de fonctions de signatures et les identifiants de types de signatures de virus qui correspondent aux identifiants de fonctions de signatures (S104) ; l'obtention de fonctions de signatures correspondant aux identifiants de fonctions de signatures, et la vérification du fichier cible grâce à l'appel des fonctions de signatures, afin d'obtenir des résultats de vérification correspondants (S106) ; et l'obtention d'un identifiant de types de signatures de virus correspondant au fichier cible selon les résultats de vérification (S108). De plus, un appareil de mise en correspondance de signatures de virus est également décrit. Ce procédé et cet appareil de mise en correspondance de signatures de virus peuvent rendre la détection et la suppression des virus plus efficaces.
