Investigatory Powers Bill

Lord Paddick Excerpts

Wednesday 27th April 2016 Lords Chamber

[Lord Keen of Elie]

I entirely concur with the noble Lord’s observations. The introduction of the double-lock mechanism in the context of the warrant underlines the importance of these developments. When the noble Lord, Lord Rosser, responded to the Statement on the Bill in November last year, he observed that it appeared that, in broad terms, the Bill had struck the difficult balance between public interest and privacy.

[Lord Paddick (LD)]

My Lords, the part of GCHQ responsible for ensuring the security of our national infrastructure, such as the national grid and our telecommunications network, is very keen on enhancing encryption. Another part of GCHQ wants to weaken encryption, so that it can access confidential information. Can the Minister say which side of GCHQ the Government are on?

[Lord Keen of Elie]

It is not necessary to be on either side of the wrong question. The position is simple: encryption is effected by means of an algorithm, which is sometimes called an encryption key. If you sequence an encryption key, you encrypt; if you reverse the process, you decrypt. This Bill will not give any party access to the encryption key, which will be held by the provider.
