ePrint Report: OPSA: Efficient and Verifiable One-Pass Secure Aggregation with TEE for Federated Learning

Zhangshuang Guan, Yulin Zhao, Zhiguo Wan, Jinsong Han

In federated learning, secure aggregation (SA) protocols like Flamingo (S\&P'23) and LERNA (ASIACRYPT'23) have achieved efficient multi-round SA in the malicious model. However, each round of their aggregation requires at least three client-server round-trip communications and lacks support for aggregation result verification. Verifiable SA schemes, such as VerSA (TDSC'21) and Eltaras et al.(TIFS'23), provide verifiable aggregation results under …
