Method and system for replacing key deployed in se of mobile terminal

Abstract

A method and system for replacing a key deployed in an SE of a mobile terminal is provided. The method requests, upon receiving a request for a replacement of a key deployed in an SE which is equipped on a mobile terminal, a new key from a service provider which has issued the replacement-requested key and receiving the new key, and transmits the new key to the mobile terminal. Accordingly, the key deployed in the SE can be replaced online by the user's request. Therefore, when it is necessary to replace the key deployed in the SE for various reasons like key exposure, the user can replace the key of the SE without visiting an institution having a key deployment device and thus user convenience can be improved.
