Techniques for secure authentication of the controlled devices

Abstract

According to an exemplary embodiment of the present disclosure, a computer program stored in a computer readable storage medium is disclosed. The computer program includes commands which cause a processor of a control device to execute steps below, the steps including: acquiring International Mobile Station Identity (IMSI) related to a Subscriber Identity Module (SIM) and location information of a controlled device from the controlled device; calculating a hash value obtained by hashing the IMSI by using a hash function; generating first signature data in which the hash value and the location information are encrypted with a private key of the control device by using an asymmetric key algorithm; generating first encryption data obtained by encrypting the first signature data with a public key of a home subscriber server by using the asymmetric key algorithm; and transmitting a connection request message including the first encryption data to the home subscriber server.
