This sounds very 1984. If the police says you have encrypted data, how can they prove it really is encrypted data? Besides, how can they prove that you do have the keys for the hypothetical encrypted data?
It sounds absurd that you have to prove your innocence. It is common principle that who accuses is responsible for proving your guilty. Besides, even in the remote situation where they could prove somehow that a pile of random bits held some confidential data, no one should be acused of not deciphering it to provide proof against himself. It sounds like inquisition :) If you deny having a deal with the devil you die, and if you confess it, you die too.
