MODULE MOUNTED PLATFORM AND METHOD FOR CHANGING FUNCTION FOR MODULE MOUNTED PLATFORM

摘要

A module mounted platform and a method for changing function for a module mounted platform are provided to ensure the integrity of a mobile device by protecting the stored data. An integrity inspection unit(230) ensures the integrity by performing an authentication process through a hash operation, and a key generating unit(250) generates a pair of symmetrical keys and a pair of cryptographic keys corresponding to an RSA(Rivest Shamir Adleman) cryptographic method. An RSA(Rivest Shamir Adleman) engine unit(260) generates encoded data by encoding the data through the pair of cryptographic keys. A non-volatile memory unit(280) stores a first code, and provides the other codes except the first code to an execution engine unit based on a mode selection signal.
