Abstract: front page image
(EN)Disclosed are a computer system and a signature verification server, a method for supporting signature verification by a computer system, and a method for signature verification. Embodiments of the present invention relate to a technique for error verification of a signature which is used when diagnosing malicious code, in which a preliminary-use signatures, for which error verification has not been completed, are distributed ahead of time to a plurality of user computers so that when files stored in a plurality of terminals are being diagnosed for malicious code, the preliminary-use signatures are applied, and the error verification is performed against the preliminary-use signatures on the basis of information collected relating to the results of the diagnosis, thus, in a plurality of user environments in which actual client vaccines are to be applied, results for simulation of a malicious code diagnosis with respect to a signature can be obtained, thereby allowing physical, spatial and temporal limitations of existing error verification of a signature to be overcome.
(FR)L'invention concerne un système informatique et un serveur de vérification de signature, un procédé de prise en charge de vérification de signature par un système informatique, et un procédé de vérification de signature. Certains modes de réalisation de la présente invention concernent une technique pour la vérification d'erreur d'une signature qui est utilisée lors du diagnostic d'un programme malveillant, dans laquelle des signatures d'utilisation préliminaire, pour lesquelles une vérification d'erreur n'a pas été achevée, sont distribuées à l'avance à une pluralité d'ordinateurs d'utilisateurs de sorte que lorsque des fichiers stockés dans une pluralité de terminaux sont en cours de diagnostic pour un programme malveillant, les signatures d'utilisation préliminaire sont appliquées, et la vérification d'erreur est effectuée sur les signatures d'utilisation préliminaire sur la base d'informations recueillies concernant les résultats du diagnostic, ainsi, dans une pluralité d'environnements d'utilisateurs dans lesquels des véritables vaccins clients doivent être appliqués, des résultats de simulation de diagnostic de programme malveillant par rapport à une signature peuvent être obtenus, ce qui permet de ne pas tenir compte de limitations physiques, spatiales et temporelles de vérification d'erreur existante d'une signature.
(KO)본 발명은, 컴퓨터 시스템 및 시그니처검증서버와, 컴퓨터 시스템의 시그니처 검증 지원 방법 및 시그니처 검증 방법이 개시되어 있다. 본 발명의 실시예들은 악성코드 진단 시 이용되는 시그니처에 대한 오진 검증에 관한 기술로서, 오진 검증이 완료되지 않은 상태의 예비적용시그니처를 다수의 사용자 컴퓨터에 선 배포하여 다수의 사용자 컴퓨터에서 저장된 파일에 대한 악성코드 진단 시 예비적용시그니처를 반영하도록 하고 그 진단결과와 관련하여 수집된 정보를 기초로 예비적용시그니처에 대한 오진 검증을 수행함으로써, 실제 클라이언트백신을 사용할 다수의 사용자 컴퓨터 환경에서 시그니처에 대한 악성코드 진단 시뮬레이션을 실행하는 결과를 도출할 수 있어 기존의 시그니처 오진 검증에서 갖는 물리적, 공간적, 시간적 한계를 극복할 수 있는 기술에 대한 것이다.
