Secure DRM-agnostic key rotation
摘要:
Systems and methods for managing provisioning of keys prior to a key rotation are provided. A license server generates a license that is associated with a renewal time. The renewal time is a time that is prior to a key rotation time, and triggers a receiver device to send a renewal request prior to the key rotation time. The renewal time may be a randomized time prior to the key rotation time that differs for different receiver devices. The license is transmitted to the receiver device. The license server then receives a renewal request from the receiver device that is triggered at the renewal time. The license server generates a next license that comprises a next key, whereby the next key is a decryption key for decrypting the encrypted signal after the key rotation time. The next license is transmitted to the receiver device prior to the key rotation time.
