A current version certificate is stored that includes a corresponding current version identifier. A current instance certificate is received from the certificate authority, wherein the current instance certificate includes the current version identifier of the current version certificate and a current instance public key corresponding to the current instance private key. The current instance certificate is sent to a local station, during a registration with the local station. A request is generated and sent to the local station. First encrypted data is received from the local station, wherein the first encrypted data includes a content key that is encrypted via the current instance public key.

Client device and local station with digital rights management and methods for use therewith

A cryptography module includes a key store having a plurality of storage locations for storing a private key as k key fragments. One or more crypto-processing segments each operate based on corresponding ones of the k key fragments to process a message in accordance with elliptic curve digital signature algorithm (ECDSA) to produce a signed message.

Elliptic curve cryptography with fragmented key processing and methods for use therewith

A cryptography module includes a key store having a plurality of storage locations for storing a key as k key fragments including a plurality of random key fragments and a remainder key fragment. One or more crypto-processing segments each operate based on corresponding ones of the k key fragments to process an input signal to produce an output signal.

Cryptography module for use with fragmented key and methods for use therewith

A current version certificate is stored that includes a corresponding current version identifier. A current instance certificate is received from the certificate authority, wherein the current instance certificate includes the current version identifier of the current version certificate and a current instance public key corresponding to the current instance private key. The current instance certificate is sent to a local station, during a registration with the local station. A request for video content is generated and sent to the local station. First encrypted data is received from the local station, wherein the first encrypted data includes a content key that is encrypted via the current instance public key. Second encrypted data is received from the local station, wherein the second encrypted data includes the video content that is encrypted via the content key.
