This $175,000 Project Grant from the National Science Foundation's (NSF) Computer and Information Science and Engineering (CISE) program (CFDA 47.070) supports research at New Mexico State University (NMSU) to develop usable interfaces for end-to-end encrypted messaging apps that enable users to choose between plausible deniability and non-repudiation. The key goals are to:

  1. Create interaction techniques that allow users to alter the content, timing, and authorship of messages in a conversation transcript, leveraging underlying cryptographic techniques to support deniability.
  2. Develop interaction techniques that help users cryptographically sign messages using identity-tied keys to enable non-repudiation.

The project will conduct user studies to assess people's ability to use these tools and understand the privacy and accountability implications. The results will advance knowledge on how people make sense of and use cryptography in practical communication contexts. The work will involve undergraduate and graduate students, providing training for the future cybersecurity workforce.
