2 APPARATUS FOR ISSUING CRYPTOGRAPHIC KEY OF INTERNET OF THINGS DEVICE USING 2-STEP AUTHENTICATION AND METHOD THEREOF

摘要

Disclosed is an apparatus and method for issuing an encryption key of an IoT device using two-step authentication. According to an embodiment of the present invention, a method for issuing an encryption key for an Internet of Things device using two-factor authentication, when a user registers an Internet of Things device using a user terminal, the Internet of Things device manages the encryption key via the Internet of Things device server. Request the server to issue an encryption key, the encryption key management server generates an encryption key and an authentication code, and the generated authentication code is transmitted to a user terminal through a separate communication channel, and then generates and generates an authentication code received from the user terminal The verification is performed by comparing the authenticated codes, and the encryption key is activated according to the verification result.
