IoT IoT Method and apparatus for authenticating Internet-Of-Things device in cloud-based Internet-Of-Things system

摘要

An IoT device according to an aspect of the present invention is an IoT device for authenticating another IoT device. The present invention comprises: a communication part which receives encrypted data generated by a cloud server from the cloud server and generates a first authentication code generated by the another IoT device and transferred through the cloud server; a control unit which encodes the encrypted data to extract an anonymous identity, and generates a second authentication code using an anonymous identity and a previously stored data structure value; and an authentication unit for authenticating the another IoT device based on the comparison result of the second authentication code.
