Billions of secure messaging users have adopted end-to-end encryption (E2EE).
Nevertheless, challenges remain. Most communication applications do not provide
E2EE, and application silos prevent interoperability. Our qualitative analysis
of privacy-conscious users' discussions of E2EE on Reddit reveals concerns
about trusting client applications with plaintext, lack of clear indicators
about how encryption works, high cost to switch apps, and concerns that most
apps are not open source. We propose InfoGuard, a system enabling E2EE for
user-to-user communication in any application. InfoGuard …
