Abstract: A security management method in a mobile communication system supporting Proxy Mobile Internet Protocol (IP). In the security management method, a Mobile Node (MN), a Serving Packet Data Service Node (S-PDSN), and an Authentication, Authorization and Accounting (AAA) server generate a security key of the Proxy Mobile IP. Upon receipt of information for authentication of a security key from the MN, the S-PDSN sends an access request message to the AAA server and receives information for verification of the security key. The S-PDSN sends a first message for requesting verification of the security-related key to a Home Agent (HA). The HA verifies the security-related key through the AAA server and sends a second message to the S-PDSN when the security-related key is verified. The S-PDSN sends a message indicating initiation of the Proxy Mobile IP, to the MN.
