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.
Lord Clement-Jones (LD)
My Lords, the noble Baroness has raised a very important issue, and it sounds from the Minister’s Answer as though the Government are somewhat behind the curve on this. When did Ministers actually get to hear about the new encrypted DoH protocol? Does it not risk blowing a very large hole in the Government’s online safety strategy set out in the White Paper?
Lord Ashton of Hyde
As I said to the noble Baroness, the Government attend the IETF. The protocol was discussed from October 2017 to October 2018, so it was during that process. As far as the online harms White Paper is concerned, the technology will potentially cause changes in enforcement by online companies, but of course it does not change the duty of care in any way. We will have to look at the alternatives to some of the most dramatic forms of enforcement, which are DNS blocking.
Lord Stevenson of Balmacara (Lab)
My Lords, if there is obscurity, it is probably in the use of the technology itself and the terminology that we have to use—DoH and the other protocols that have been referred to are complicated. At heart, there are two issues at stake, are there not? The first is that the intentions of DoH, as the Minister said, are quite helpful in terms of protecting identity, and we do not want to lose that. On the other hand, it makes it difficult, as has been said, to see how the Government can continue with their current plan. We support the Digital Economy Act approach to age-appropriate design, and we hope that that will not be affected. We also think that the soon to be legislated for—we hope—duty of care on all companies to protect users of their services will help. I note that the Minister says in his recent letter that there is a requirement on the Secretary of State to carry out a review of the impact and effectiveness of the regulatory framework included in the DEA within the next 12 to 18 months. Can he confirm that the issue of DoH will be included?
Lord Ashton of Hyde
Clearly, DoH is on the agenda at DCMS and will be included everywhere it is relevant. On the consideration of enforcement—as I said before, it may require changes to potential enforcement mechanisms—we are aware that there are other enforcement mechanisms. It is not true to say that you cannot block sites; it makes it more difficult, and you have to do it in a different way.
The Countess of Mar (CB)
My Lords, for the uninitiated, can the noble Lord tell us what DoH means —very briefly, please?
Lord Ashton of Hyde
It is not possible to do so very briefly. It means that, when you send a request to a server and you have to work out which server you are going to by finding out the IP address, the message is encrypted so that the intervening servers are not able to look at what is in the message. It encrypts the message that is sent to the servers. What that means is that, whereas previously every server along the route could see what was in the message, now only the browser will have the ability to look at it, and that will put more power in the hands of the browsers.
The Lord Privy Seal (Baroness Evans of Bowes Park) (Con)
My Lords, if we are very quick and we actually ask questions, we might get two in. We will start with the Labour Benches.
Lord West of Spithead
My Lords, I thought I understood this subject until the Minister explained it a minute ago. This is a very serious issue. I was unclear from his answer: is this going to be addressed in the White Paper? Will the new officer who is being appointed have the ability to look at this issue when the White Paper comes out?
Lord Ashton of Hyde
It is not something that the White Paper per se can look at, because it is not within the purview of the Government. The protocol is designed by the IETF, which is not a government body; it is a standards body, so to that extent it is not possible. Obviously, however, when it comes to regulating and the powers that the regulator can use, the White Paper is consulting precisely on those matters, which include DNS blocking, so it can be considered in the consultation.
