| titleOfInvention | Protection of digital content |
| abstract | A method of processing digital content on a content processing device includes receiving digital content that has been protected through encoding and/or scrambling using a predetermined algorithm. Additionally, an obfuscated computer program is received that is associated with the protected digital content for execution by the processing device. The program includes authentication instructions for performing authentication of the processing device and conversion instructions for performing at least a part of decoding and/or descrambling of the protected digital content in dependence on a response of the processing device to an authentication challenge. According to the method, a multi-round zero-knowledge algorithm is used for authenticating the processing device. Execution of respective rounds of the zero-knowledge algorithm is time-sequentially intermixed with content conversion of sequential parts of the digital content. |
