Paper 2021/988
Concurrent Signatures from a Variety of Keys
George Teseleanu
Abstract
Concurrent signatures allow two entities to produce two ambiguous signatures that become binding once an extra piece of information (called the keystone) is released. Such a signature is developed by Chen \emph{et al.}, but it restricts signers to using the same public parameters. We describe and analyse a new concurrent signature that allows users to sign documents even if they use different underlying hard problems when generating their public parameters.
