We observe that finding invalid signatures in batches of signatures that fail batch verification is an instance of the classical group testing problem. We survey relevant group testing techniques, and present and compare new sequential and parallel algorithms for finding invalid signatures based on group testing algorithms. Of the five new algorithms, three show improved performance for many parameter choices, and the performance gains are especially notable when multiple processors are available.
