Abstract
Methods and systems related to provisioning a secure connection are disclosed. One disclosed method includes storing a device secret on a secure element in a first device, storing a mapping from the device secret to a device identifier of the first device on a cloud architecture, generating a pairing key using a first connection protocol key generator on the secure element and the device secret, and generating the pairing key using a second connection protocol key generator on the cloud architecture and the device secret. The method also includes transmitting the pairing key from the cloud architecture to a second device in response to receiving the device identifier, mutually authenticating the first and second device using the pairing key, and adding the secure connection to the inter-device connection using the pairing key as stored on the first device and as stored on the second device.
