Patent ID: 10523437

Abstract:
An Authentication Of Things (AOT) system includes a cloud server configured to control a cloud domain connected with a plurality of devices, a home server configured to control a home server connected with a plurality of devices, a first device corresponding to a new device, and a second device of a root user connected with the home domain while authentication is completed in the home server. In this case, the first device loads cryptographic material of the cloud server from the cloud server in a pre-deployment stage, the cryptographic material includes at least one selected from the group consisting of an identifier of the first device in the cloud server, a first private key of an ID-based cryptography system of the first device in the cloud server, a first pairwise key of the first device in the cloud server, and a counter of the first device, and if the first device is shipped to a trader, the cloud server deletes the first private key from the cloud server.
