We recently integrated it successfully into the OpenFL framework: https://github.com/securefederatedai/openfl . Please check the implementation there within openfl-tutorials/experimental/CrowdGuard.

The corresponding paper was published as: Rieger, Krauß, Miettinen, Dmitrienko, and Sadeghi, "Crowdguard: Federated backdoor detection in Federated Learning" at NDSS 2024. Paper available here.
