    • 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.
    • 描述了涉及具有不同安全简档的多个设备的认证和/或绑定的系统和方法。 在一个方面,当第二设备从内容提供商请求访问内容时,具有较高安全性配置的第一设备可以保证具有较低安全性配置文件的第二设备的真实性。 可以通过允许第一设备将其数字签名重叠在由第二设备签名和发送的注册请求上来实现加密过程。 具有较低安全性配置的第二设备可以在预定时间段内从内容提供商或源访问内容,即使当第二设备不通过第一设备访问内容时。
