A first look at the usability of bitcoin key management
This work addresses usability issues for Bitcoin users, but it is incremental as it applies existing evaluation methods to a new context.
The paper tackled the problem of evaluating Bitcoin key management usability by developing a framework and assessing six Bitcoin clients, finding that Bitcoin shares key management challenges with other domains but offers a unique opportunity to rethink user key management.
Bitcoin users are directly or indirectly forced to deal with public key cryptography, which has a number of security and usability challenges that differ from the password-based authentication underlying most online banking services. Users must ensure that keys are simultaneously accessible, resistant to digital theft and resilient to loss. In this paper, we contribute an evaluation framework for comparing Bitcoin key management approaches, and conduct a broad usability evaluation of six representative Bitcoin clients. We find that Bitcoin shares many of the fundamental challenges of key management known from other domains, but that Bitcoin may present a unique opportunity to rethink key management for end users.
