SECURITY MANAGEMENT DEVICE FOR MOBILE CONTENTS PROVIDER AND METHOD THEREFOR

摘要

PURPOSE: A security management device for an MCP(Mobile Contents Provider) and a method therefor are provided to locate a wireless security proxy between an MCP and a user's mobile terminal, and to apply an mRSA(mediated Rivest-Shamir-Adleman) technology between the wireless security proxy and the MCP, thereby immediately revoking a security capability of the attached MCP. CONSTITUTION: A mobile terminal security manager(2) manages an mRSA personal key fragment of a user's mobile terminal, and processes a signature request of the mobile terminal. An MCP security manager(3) manages the mRSA personal key fragment of an MCP, processes an mRSA signature of the MCP, and checks whether a message transmitted from the MCP has a failure related to security obstruction. If any abnormality is checked by the MCP security manager(3), an MCP security capability revoker(4) revokes a security capability of the MCP. The MCP security manager(3) previously receives mRSA personal key fragments of each mobile terminal and the mRSA personal key fragment of the MCP while registering certifications of the mobile station and the MCP.
