Intel is investigating how a master key for the High-bandwidth Digital Content Protection [HDCP] protocol used to protect digital content made its way to the Internet.
Developed by Intel, the HDCP protocol is used to protect video and audio content as it is transmitted between devices such as Blu-ray players and high-definition televisions [HDTVs] and to verify the device receiving the content is licensed to do so.
The master key is used to generate keys meant for consumer devices. On 14 September, it was reported that a secret master key for HDCP had been posted on the Internet. Intel confirmed the key was legitimate on 16 September.
