Special hardware designed to break a copy protection. > Is my customized linux "illegal software" under this nonsense? No, just untrusted, so you won't be able to play DVDs with it. Unless you add some tricks to it so the DVD believes it is talking to a trusted player, which would be somewhere along the lines of writing software to decrypt eBooks... :-/ > The people proposing such nonsense should get real - there are quite a ways > to modify processes execution, the simplest being a debugger. I believe they have thought about this. Trusted software can only be debugged on a special "developer" machine. My personal favourite would be the "carefully crafted" DVD, which uses a buffer overflow in a player routine (where people optimize for speed over security anyway). :-) Simon -- GPG Fingerprint: 040E B5F7 84F1 4FBC CEAD ADC6 18A0 CC8D 5706 A4B4 -------------- next part -------------- A non-text attachment was scrubbed...
