An Inconvenient Trust: User Attitudes Toward Security and Usability Tradeoffs...
summary
A 52-person lab study uses a modified Mailvelope plugin to compare a manual exchange (PGP-like) model versus a key-directory or registration model (think iMessage / Google End-to-End). Participants understand both, rate exchange as more work and registration as good enough; 48/52 trust exchange, 38/52 trust registration, and 34/52 correctly reason about misconfigurations. Two proposed registration variants—split-storage confidentiality and auditor-based verification—raise mixed reactions. Watch if concrete user numbers, the plugin-based tasks, and these measurable tradeoffs matter.
