Thanks Martin! Following up with a few more details. In [2025/1891](https://eprint.iacr.org/2025/1891), we propose using signatures to authenticate impressions and reports to the aggregation service. We show how this can be done efficiently using algebraic signatures in the MPC aggregation setting. We'd love to get some feedback from the community group on what types of fraud they are worried about in their settings. Are signatures a useful mitigation mechanism? I'm attaching a few more links below: - [Slides](https://docs.google.com/presentation/d/197aw9W3VpNolSQPr2uZrdJwdsJBOyMGEjVGmGj5KdF8/edit?usp=sharing): Slide deck introducing the main ideas from our work. - [Code](https://github.com/nirvantyagi/ppa-fraud-ssa): Open source repository of our prototype implementation. It includes some benchmarks comparing it against the prio3 library L1 norm validity check. -- GitHub Notification of comment by nirvantyagi Please view or discuss this issue at https://github.com/patcg/meetings/issues/235#issuecomment-3514956829 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
