| Intern Alfred
Our summer intern Alfred just graduated high-school and is preparing to attend a major university to focus on a technical degree. He has a personal interest in privacy and security, and is working with us on a variety of projects this summer as part of a broad, crash-course in all things Guardian Project!
Last week, I worked with three different apps for the iPhone that, when they work together, allow for a secure and private mobile internet experience.

Improving website resilience with LibResilient and IPFS
Posted on June 15, 2023
| uniq
We’re always looking for techniques to make services more resilient to all sorts of issues. That’s why we took special interest in LibResilient and mapped out it’s capabilities. It’s a JavaScript library for decentralized content delivery in web-browsers and markets itself as easy to deploy to any website. We’ve looked at LibResilient primarily in the context of static websites. While it should work with dynamic websites too, that was out of focus for us.

EU should not require sharing unpatched vulnerabilities
Posted on June 11, 2023
| EDRi.org
We, the undersigned organisations, write to express our concern with vulnerability disclosure requirements under the proposed Cyber Resilience Act (CRA). The CRA’s objective to encourage software publishers to patch vulnerabilities and report cyber incidents is salutary. However, the CRA’s mandatory disclosure of unmitigated vulnerabilities will undermine the security of digital products and the individuals who use them.
The CRA would require organisations to disclose software vulnerabilities to government agencies within 24 hours of exploitation (Cyber Resilience Act, Articles 11.

Day Four of the 116th IETF meeting in Yokohama Japan. For the rundown on Day Three, see my daily report.
The IETF is getting serious about interoperability among messaging services (this might have had something to do with it). The charter for the Messaging Layer Security Working Group (MLS) specifically excluded interoperability, though the group organized a draft that addressed the basic concepts that would allow MLS-compatible systems to federate. In early 2023, a new Working Group - More Instant Messaging Interoperability (MIMI) - was chartered to expand on the MLS federation work.

The long-running work on MASQUE - proxying all network-layer datatypes over QUIC (HTTP/3) - is nearing completion, with the specification for Proxying IP in HTTP in IESG review. With these components in place, the original MASQUE concept - a non-probable relay for client traffic providing privacy guarantees - has been revived, now defined within the new framework and leveraging HTTP Unprompted Authentication.

The OHAI Working Group has submitted the core draft of Oblivious HTTP Application Intermediation to the RFC Editor for editorial finalization and publication. OHAI is designed to support transational uses of the HTTP protocol that seek IP address privacy (by means of a relay pair, one associated with the client and one associated with the target resource).

This post begins a daily blog, live from the 116th meeting of the Internet Engineering Task Force in Yokohama, Japan, March 25-31, 2023. We’re focusing on standards activities of importance to the Internet Freedom community.
Since IETF114 (report), the Privacy Preserving Measurement Working Group has been deliberating over two distinct proposals offering very different technical methodologies for undertaking measurement activities while respecting user privacy. STAR offers an approach called k-anonymity - reporting a measurement value only if k or more parties are also reporting the same value.

Arti, next-gen Tor on mobile
Posted on March 4, 2023
| uniq
For software projects with recurring bugs, efficiency or security issues there’s a joke making the rounds in the software industry: “Let’s re-write it in Rust!” It’s a fairly new low-level programming language with the declared goal to help developers avoid entire classes of bugs, security issues and other pitfalls. Re-writing software is very time consuming, so it rarely happens, especially when just one more fix will keep a project up and running.

Steps towards trusted VPNs
Posted on February 28, 2023
| Hans-Christoph Steiner
VPNs have become quite popular in recent years for a number of reasons, and more and more they are being touted as a privacy tool. The question is whether using a VPN does improve privacy. It is clear that VPNs are quite useful for getting access to things on the internet when direct connections are blocked. VPN providers include a number of tactics in both their client apps and server infrastructure to ensure that their users are able to make a connection.

Smart phones have brought us so many wonderful capabilities. They let people around the world access vast realms of information. They let app developers solve problems large and small in a way most relevent to their local context. They are personal computers for the world. They also have given surveillance capitalism an unprecedented reach into everyone’s lives. Repressive governments use them in ways that the East German Stasi secret police could only have dreamed of.

The Search for Ethical Apps: Let's start with governments
Posted on September 1, 2022
| Hans-Christoph Steiner
Governments across the world are moving services to mobile apps. The vast majority of these apps are only available in the Google Play store or in the Apple App store. Installing apps from these services requires users to agree to their terms of service. This means governments require their citizens to sign opaque and privacy invading contracts with foreign Big Tech in order to use digital services. This feeds ever more into Big Tech data control, filtering, and information bubbles.

Serving Websites Privately Over Tor Onion Services (From Your Laptop!)
Posted on August 29, 2022
| Shanzay, Summer Intern
In this day and age when our data is consistently being tracked and profited off of, sharing information safely and securely is difficult. However, that does not necessarily mean that all network services are subject to such scrutiny. Users now have the ability to combine the security of HTTPS with the privacy benefits of Tor Browser and share information through Tor’s anonymous network services – Onion Services. By using an onion service, users can hide their location while active, connect to other Tor users, and retain their privacy throughout.

| Shanzay, Summer Intern
Close your eyes and imagine. You are sitting, designing the next game-changing innovative idea; however, you are not worried about any information leakage or spread, as you are in control. You not only hold ownership of your data, but with each online activity, your fear of being tracked dissipates more. This new internet you explore on understands each input, tailoring the content to your specific needs as it no longer runs on basic commands, but rather uses the combination of technologies and concepts such as machine learning, big data, and decentralized ledger technology to process information in a smart, human-like manner.

Lucas Pardue, of Cloudflare and co-chair of the QUIC Working Group, gave a not-so-tongue-in-cheek talk about the breakdown of the OSI layering model of the Internet. His focus was on the top of the stack, illustrating handsomely what QUIC and HTTP/3 have done (unknowingly to most) to our perception of layers.

Day One of the 114th IETF meeting in Philadelphia USA.
With privacy a key consideration in new protocol design, cryptography has become a major focus of IETF activities. The Internet Research Task Force (IRTF) has the Crypto Forum Research Group where new cryptography schemes are brought forward and vetted for use in IETF protocols. Well, new is a misnomer. Much of the mathematics has long been defined, at least at its core, and the work is rather being brought into the IETF context where important engineering considerations apply: use of memory (at rest or in flight), processing required, round-trips required, etc.
