METHOD AND APPARATUS FOR GENERATING USER SECRET KEY IN MOBILE COMMUNICATION SYSTEM

摘要

A method and an apparatus for creating an user secret key in a mobile communication system are provided to create an user secret key which is a master key through a verified password algorithm and a secure mechanism in a mobile communication system of a third generation partnership project manner. A method and an apparatus for creating an user secret key in a mobile communication system includes a step of creating a key factor by inputting an operator secret key and a seed to a Hash function based on a block password(101). The created key factor is a key of algorithm of the block password. An input factor is created by operating the algorithm with an Output FeedBack mode by inputting user information for creating a user secret key into the algorithm of the block password(102). The created input factor is an input value of a keyed Hash function. The user secret key is created with the key factor which is the keyed Hash function(103).
