A client application of a device queries/interrogates a secure device identity module of the device to obtain a device identifier of the device and a signed string generated by the security device identity module using a private key unique to the device. The client application of the device sends to an authorization server a request containing the device identifier and the signed string. Depending on an authentication result obtained for the device based on the device identity, the authorization server sends to the device an access token that enables the client application to access a resource.

Securely authorizing client applications on devices to hosted services

A router has at least one outbound interface configured for establishing multiple IP-based secure connections (i.e., tunnels) with respective destinations based on transmission of encrypted data packets via the IP-based secure connections. The encrypted data packets are generated by a cryptographic module, where each encrypted packet successively output from the cryptographic module includes a corresponding successively-unique sequence number. The supply of data packets to the cryptographic module is controlled by a queue controller: the queue controller assigns, for each secure connection, a corresponding queuing module configured for outputting a group of data packets associated with the corresponding secure connection according to a corresponding assigned maximum output bandwidth. Each queuing module also is configured for reordering the corresponding group of data packets according to a determined quality of service policy and the corresponding assigned maximum output bandwidth.
