We are not considering a publication of abstract principles but of specified
weaknesses in named code. Do be able do this, the researcher has had his
head well and truly 'under the bonnet' of that proprietary code and will not
easily be able to show otherwise. In the case of a copy protection
algorithm, it will be unique to its owner.
