Building a One-Time-Password Token Authentication Infrastructure
Jonathan Hanks, LIGO Lab/California Institute of Technology, and Abe Singer, Laser Interferometer Gravitational Wave Observatory, Caltech
One-time-passwords provide more security than passwords, but what about risks, multiple sites, provisioning and distribution? At LIGO, our infrastructure supports using a single token across multiple sites, and tolerates network failures while minimizing the overhead in managing and distributing tokens. We don’t have to to trust third party services, use “black box” software, or custom client software. We also support OTP for Kerberos without any client-side modifications. In this talk: our approach to evaluating and deploying token authentication includes risks, requirements, system architecture, supporting multiple sites, fault tolerance, Kerberos, and our experiences using it for a couple of years.
