ABSTRACT:
In a cryptographic system, a certificate is used to provide information regarding a client device. The certificate is blindly signed by a certifying authority to preserve the anonymity of the client device. However, information is encoded into the signature so that a content server can readily verify security attributes of the client device and make decisions regarding the delivery of electronic content to the client device based on those security attributes.
