Summary: | A distribution system and method for distributing digital information is provided, which has high recoverability from a security breach. The distribution system comprises a server (200) and a computing device (110). During an enrollment phase, the computing device obtains a first response from an integrated physically unclonable function (150) integrated in the computing device. The system comprises an enrollment module (130) for determining helper data from a decryption key and the first response to enable later reconstruction of the decryption key from the helper data and a second response obtained from the physically unclonable function. During a reconstruction phase, which occurs after the enrollment phase and typically after a security breach has occurred that revealed data and/or programming code of the computing device, the server may encrypt digital information using an encryption module (220) with a cryptographic encryption key corresponding to the decryption key. |
