METHODS AND DEVICES FOR BOOTSTRAPPING OF RESOURCE CONSTRAINED DEVICES

摘要

It is disclosed a method of establishing a secure connection between a device (1) and a network-based entity (5), NAF, via an access gateway (3), where the device and a network-based bootstrapping server (6), BSF, have a pre-established trust relationship. The method comprises the access gateway acting as a proxy between the device and the BSF. The method comprises using a reference to a NAF (5) received from the BSF to securely authenticate the device to the NAF, and sending an identity of the access gateway to the NAF and using that identity to authorise the device to use the access gateway. The method further comprising authenticating the access gateway identity at the BSF and/or the NAF. The access gateway may relay messages to the device over a non-HTTP link.
