Title:
Authentication and sole control at a high level of assurance on widespread smartphones with threshold signatures
Authors: Sander Q. Dijkhuis
Abstract:How to be assured that a user entered their PIN on their smartphone? The question is especially relevant when deploying remotely secured services such as with mobile wallets for digital identity and banking, which typically deploy a server side backed by a hardware security module (HSM). As long as the server can be trusted, authentication can be performed with high assurance, but it is challenging to guarantee sole control. This report defines an approach in terms of an abstract security problem and a concrete solution based on threshold signatures. It can be applied to use cases such as HSM-backed mobile identity wallets and other identification means.
