Title: COMPUTER SYSTEM AND SIGNATURE VERIFICATION SERVER
Abstract:
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.
