Abstract
Systems and methods are described that relate to authentication and/or binding of multiple devices with varying security profiles. In one aspect, a first device with a higher security profile may vouch for the authenticity of a second device with a lower security profile when the second device requests access for content from a content provider. The vouching process may be implemented by allowing the first device to overlay its digital signature on a registration request that has been signed and transmitted by the second device. The second device with the lower security profile may access content from the content provider or source for a predetermined time period, even when the second device does not access content through the first device.
