AGENT DEVICE AND METHOD FOR SHARING SECURITY INFORMATION BASED ON ANONYMOUS IDENTIFIER BETWEEN SECURITY MANAGEMENT DOMAINS

摘要

PURPOSE: An agent device for sharing security information based an anonymous identifier among security management domains and a method thereof are provided to share security information based on an identifier based on hash, thereby preventing leakage of personal information included in the security information. CONSTITUTION: An identifier conversion unit(220) converts a real name identifier included in security information into an anonymous identifier and converts security information based on the real name identifier into security information based on the anonymous identifier. A security information communication unit(240) transmits the security information based on the anonymous identifier to the outside of a security management domain in order that security management domains share the security information. The identifier conversion unit converts the real name identifier included in the security information into a hash identifier which is the anonymous identifier by using a one-way hash function.
