System and method of managing encryption key management system for mobile terminals

摘要

An encryption key management method for mobile terminals for providing at least one mobile terminal which is connected to a network to use services with an encryption key required for issuing a certificate which is needed for the services and managed by a certification authority by using an encryption key management server is provided. The method includes operations of: a registration requesting operation where the mobile terminal generates an encryption key registration request; an encryption key managing operation where the encryption key management server generates and manages the encryption key in response to the encryption key registration request; a transferring operation of sending the generated encryption key to the mobile terminal; and a security service providing operation of receiving the certificate managed by the certification authority and providing selective security services specific to the content of the services provided to the mobile terminal. The method can relieve the hardware load of mobile terminals while providing a security service using various conventional certification authorities.
