Asymptotically shorter secret keys in Information-Theoretic Distributed Point Functions are now possible, thanks to a novel construction leveraging private information retrieval.

Ring-based DPFs slash key sizes and communication overhead in error-detecting private information retrieval, finally making itED-PIR practical for high-security, large-scale deployments.

Achieve secure outsourced decision tree evaluation without any communication between servers, unlocking faster and more scalable MLaaS deployments.
