Internet Encryption

Baroness Thornton Excerpts

Tuesday 14th May 2019 Lords Chamber

Asked by

[Baroness Thornton]

To ask Her Majesty’s Government what assessment they have made of the deployment of the Internet Engineering Task Force’s new “DNS over HTTPS” protocol and its implications for the blocking of content by internet service providers and the Internet Watch Foundation; and what steps they intend to take in response.

[Baroness Thornton (Lab)]

My Lords, I beg leave to ask the Question standing in my name on the Order Paper and, in doing so, declare as an interest that, until recently, my husband was an unpaid adviser to successive Governments on matters concerning online child safety for the last 17 years.

[The Parliamentary Under-Secretary of State, Department for Digital, Culture, Media and Sport (Lord Ashton of Hyde) (Con)]

My Lords, DCMS is working together with the National Cyber Security Centre to understand and resolve the implications of DNS over HTTPS, also referred to as DoH, for the blocking of content online. This involves liaising across government and engaging with industry at all levels, operators, internet service providers, browser providers and pan-industry organisations to understand rollout options and influence the way ahead. The rollout of DoH is a complex commercial and technical issue revolving around the global nature of the internet.

[Baroness Thornton]

My Lords, I thank the Minister for that Answer, and I apologise to the House for this somewhat geeky Question. This Question concerns the danger posed to existing internet safety mechanisms by an encryption protocol that, if implemented, would render useless the family filters in millions of homes and the ability to track down illegal content by organisations such as the Internet Watch Foundation. Does the Minister agree that there is a fundamental and very concerning lack of accountability when obscure technical groups, peopled largely by the employees of the big internet companies, take decisions that have major public policy implications with enormous consequences for all of us and the safety of our children? What engagement have the British Government had with the internet companies that are represented on the Internet Engineering Task Force about this matter?

[Lord Ashton of Hyde]

My Lords, I thank the noble Baroness for discussing this with me beforehand, which was very welcome. I agree that there may be serious consequences from DoH. The DoH protocol has been defined by the Internet Engineering Task Force. Where I do not agree with the noble Baroness is that this is not an obscure organisation; it has been the dominant internet technical standards organisation for 30-plus years and has attendants from civil society, academia and the UK Government as well as the industry. The proceedings are available online and are not restricted. It is important to know that DoH has not been rolled out yet and the picture is complex—there are pros to DoH as well as cons. We will continue to be part of these discussions; indeed, there was a meeting last week, convened by the NCSC, with DCMS and industry stakeholders present.
