Projects: Brainstorming Thread

[elimisteve]

Which projects deserve our attention?

Projects that could (or already do) impact a large number of users, or projects that could (or do) affect many particularly vulnerable users (e.g., activists, journalists, Muslims, etc).

[elimisteve]

Signal

• Improvements to Signal would help millions of people. What do you all think is most critical to add/change?
  • In my experience, the iOS app could use some love; last I checked, timestamps weren't showing correctly and so the people I message didn't know when I sent them messages :-\

[elimisteve]

Tor

Tor is at least partially blocked in several parts of the world (e.g., China). I know that Pluggable Transports try to get around this. What other anti-censorship techniques are being used?

[elimisteve]

GPG

Usability is a gigantic hurdle to getting more people to use GPG, but I talked to a core team member and he pointed out that the UIs through which non-technical people use GPG are mail clients, and the core GPG people don't really work on mail clients.

EDIT: If we're interested in contributing to GPG directly, we can start off by checking out https://bugs.gnupg.org/ and https://lists.gnupg.org/pipermail/gnupg-devel/ .

Mailpile

Mailpile is an open source (Python + Tornado), crowd-funded mail client that integrates GPG encryption in from the start and aims to be very user-friendly.

Its core contributor recently asked for code review help here! https://www.mailpile.is/blog/2016-09-23_Rebooting_Mailpile_Development.html

Mailpile has tons of potential and is nearing a 1.0 release. I've reached out to the core dev to see how interested he is in our help!

EDIT: talked to the lead dev (Twitter convo) and he pointed me to these "Low Hanging Fruit" issues: https://github.com/mailpile/Mailpile/issues?q=is%3Aissue+is%3Aopen+label%3A%22Low+Hanging+Fruit%22

[elimisteve]

Idea: off-device encrypted video recordings

• Problem: activists want to film police in order to check for abuses, but are at risk of recording their friends doing something that could be construed as illegal or that they could otherwise get punished for.
• Second problem: recording this video on smartphones using normal video recording software isn't good enough because their devices could easily be seized by police if a police abuse is recorded.
• Current trade-off: activists either have to record locally and risk having their devices seized, or they publicly stream the video and risk getting other activists in trouble.
• Solution we could build: a smartphone app that encrypts the video files and uploads them in real-time (perhaps to Dropbox or a server) such that those encrypted videos can only be decrypted by the person who performed the recording.

EDIT: at our first event (and afterward, but Lizzie at Noisebridge), someone mentioned the ACLU has has apps for recording the police, and they send the video footage to the ACLU. So if we added encryption to these apps, that might be the best/fastest way to solve this secure-video-recording problem for people!

Response to: off-device encrypted video recordings

1. Use Eye-fi card in video camera (wi-fi SD card for non-wi-fi devices)
2. Setup encrypted Linux laptop acting as wi-fi access point for the Eye-fi card
3. Laptop encrypts and records video files to hard disk.
4. Optionally, the laptop can upload stored video files over a MyFi-class cellular interface.
5. Prefer public key encryption for video files.

Encrypted MicroSD cards

Proposal: (re)code firmware for a MicroSD card to provide asymmetric encryption of stored data.

Motivation: for journalists, whistleblowers and anyone wanting secure storage on SD cards, for use in devices that do not encrypt (most any A/V device).

Background: A few years back, Bunnie Huang was bringing the Chumby to production (an internet appliance), and ran into quality issues with MicroSD cards from some manufacturers.

This led to a teardown of cards to learn how they work, the discovery that all contain microcontrollers to manage the mapping of bad blocks and moving data, and finally the release of a toolchain for building a firmware for certain manufacturer's cards.

Asymmetric encrypted browser proxy

Provides bidirectional OpenPGP encryption as a browser extension. Basically a VPN but not utilising OS VPN features. Would require a proxy server equipped with matching software.

There exists a number of "pure" JavaScript OpenPGP implementations, plus there are Node.js wrappers for pgp/gpg on the server.

Let's build a mixnet! A high latency network for anonymized messaging.

Lately I've been cleaning up the sphinx mixnet packet format python reference implementation written by Ian Goldberg and George Danezis:

https://github.com/david415/sphinxmixcrypto

However we recently noticed these:

https://github.com/UCL-InfoSec/sphinx
https://github.com/UCL-InfoSec/loopix

Mixnets can in theory resist the traffic corelation attacks by global passive adversaries. There's a huge amount of literature about mixnets. These are my favorite papers so far:

• http://freehaven.net/anonbib/cache/DBLP:conf/sp/DanezisG09.pdf
• http://freehaven.net/anonbib/cache/danezis:wpes2003.pdf
• http://freehaven.net/anonbib/cache/mix-acc.pdf
• http://freehaven.net/anonbib/cache/trickle02.pdf

Copperhead+Tor

https://blog.torproject.org/blog/mission-improbable-hardening-android-security-and-privacy
A hardened privacy preserving phone that supports Nexus and Pixel devices.

Tons of projects are possible, involving the following skills:

• New Device Support (bash scripting, light python hacking.. No firmware knowledge needed)
• Helping to keep up with new Android filesystem features, like FEC (light python hacking)
• Fixing OrWall bugs/UI issues (Java)
• Building standalone build systems or independent versions of required portions of the build tree (Java, gradle, Makefile maze wrangling)
• Plenty more. See the blog post and https://github.com/mikeperry-tor/mission-improbable/blob/master/README.md

EDIT: Lizzie contacted a core Copperhead developer for us and he pointed us toward these issues that we could contribute to -- https://github.com/copperhead/bugtracker/issues?q=is%3Aopen+is%3Aissue+label%3Aproject

EDIT: A Copperhead developer said that ^^Lizzie's^^ link is still a great place to start, and that we can join them in IRC: https://twitter.com/_copperj/status/804489672093270016 .

pretty Easy privacy (p≡p)

A peer-to-peer cross-platform approach with an engine and adapters to automatically drive different crypto standards (including automatic key management & peer-to-peer key synchronization across devices) in a way that for a user no special steps need be taken to use end-to-end crypto and such that trust can easily be checked by strings in the user's natural language ("Trustwords") instead of hexadecimal fingerprints. The principle is that of Privacy by Default.

The software is to be integrated in existing software or to be the crypto base for new applications. Currently GnuPG and NetPGP are used for crypto (PGP). The plan is to easily encrypt everything text-based, including meta-data encryption (encryption for XMPP/OTR, with Axolotl, over Tox and GNUnet to be supported anytime soon).

Everything is Free Software under the GNU GPL v3.

• Code
  • p≡p core / base code (engine, adapters & libs): https://letsencrypt.pep.foundation/trac/
    • p≡p adapters: Java (JNI), JavaScript (JSON), Objective-C/Swift/iOS, Python, Qt, Windows (COM).
  • K-9 (fork) integration (Android) beta: https://cacert.pep-security.lu/gitlab/android/k9-pep (CAcert)
  • Outlook add-in stable: https://cacert.pep-security.lu/trac/ (CAcert)
  • Enigmail integration ongoing (cf. for "pEp" commits): https://sourceforge.net/p/enigmail/source/ci/master/tree/
  • There's further active work undergoing to bring p≡p to KMail and iOS (own app): source code yet to be released.
• p≡p Whitepaper outlining the general idea: https://pep.foundation/docs/pEp-whitepaper.pdf
• p≡p engine code audit: https://pep.foundation/blog/press-release--pep-releases-first-code-audit-of-the-pep-engine/index.html
