Introduction
Modern parallel and distributed computing frameworks often rely on AllReduce, facing increasing risks of collusion and inference attacks. Traditional Homomorphic Encryption (HE) solutions introduce high overhead, require secure key exchanges, and are vulnerable to collusion. DPAR addresses these limitations by introducing Differential Privacy (DP) into AllReduce, offering provable protection and superior performance.
DPAR Innovations
DPAR introduces three key innovations: integrating Differential Privacy (DP) for true secure AllReduce, scalable noise growth for large-scale usability, and performance optimization with a noise pool. These innovations eliminate secure channel dependency, prevent collusion attacks, and reduce performance overhead compared to HE-based methods.
Security & Scalability
DPAR provides strong privacy guarantees, scaling its injected noise with O(√N) while maintaining accuracy. It is provably resilient to membership inference and statistical inference attacks, ensuring data confidentiality even with malicious actors. Empirical validation confirms that DPAR's noise distribution aligns with theoretical predictions across various scales.
Performance
DPAR significantly reduces computational overhead by eliminating decryption steps and optimizing noise generation with a noise pool. It achieves near-native MPI performance and outperforms HEAR by up to 34.7% in AI workloads, demonstrating superior latency and throughput across various rank configurations and message sizes.

Real-World Impact: Large-Scale AI Workloads
Deep Learning Models on HPC Clusters
DPAR has been validated on real-world deep neural network (DNN) and large language models (DeepSeek models) on Delta and Frontier supercomputers. It consistently maintained strong privacy guarantees with minimal performance overhead across various scales, outperforming HEAR significantly. For example, on ResNet-152, DPAR reduced overhead to 12.2% compared to HEAR's 48.6%, achieving a 34.7% speedup at 2048 ranks. This demonstrates DPAR's practical advantage in critical AI training scenarios where secure and efficient data aggregation is paramount.
