Re: Wow, I didn't realize it had such a glaring weakness
said by vpoko  :What's the purpose of a "processing key"? Why introduce a weakness like that into their protocol? I can't remember the source of the information (Ed Felton maybe, at Freedom to Tinker?), but if you read the history of these DRM methods, it appears that some decisions have been made based on things such as how many circuit cards would be needed to implement the DRM - the circuitry for really robust DRM would take 2 ckt boards, but this would add cost and the decision was made to go with a one ckt board, less robust "protection" to keep costs down.
I'm not saying that's why this weakness occurred, just that these DRM schemes are so easily compromisable sometimes because of decisions like these. |
