Paragraphs 13 and 14 of the article refered to above read as follows:
"It is Part III of the Bill, however, which is most likely to contravene
the Convention [the European Convention of Human Rights]. Section 46 gives the Home Secretary the power to compel the surrender of keys used to encrypt communications data. Failure to comply carries a prison sentence of two years. If someone cannot comply
because they have lost or forgotten the key then they have to prove that
to the satisfaction of a court. In other words, the burden of proof is
shifted from the prosecution to the defence – one is presumed guilty until
proved innocent. And how do you prove that you have forgotten something?
"Even more oppressive is the Bill's creation of a secondary offence –
revealing that you have been required to supply, or supplied, a decryption
key – which carries an even stiffer penalty. Under the terms of the Bill,
for example, the police could arrive at 4am and demand that you produce
such a key. If you were unable to comply and were taken in for
questioning, it would be a criminal offence punishable by five years'
imprisonment to explain to your family why you were being dragged off."
