Patent attributes
An electronic device (such as an IoT controller) that distributes a link key is described. During operation, while an administrator is logged in, the electronic device may receive the link key using a secure widget, where the link key may facilitate secure communication via a link. Then, the electronic device may generate an access key, and may generate an encrypted version of the link key based at least in part on the access key and the link key, where the access key enables access to the link key based at least in part on the encrypted version of the link key. Next, the electronic device may store the link key, the access key and/or the encrypted version of the link key in a trusted envelope or partition in the memory with encryption. Moreover, when the administrator logs out, the electronic device may disable access to the trusted envelope.
