Abstract

To address the problems that the current federated learning verifiable aggregation scheme has excessive user communication overhead, cannot tolerate user dropout, and user dropout results in lower verification efficiency, this paper proposed an efficient verifiable aggregation scheme based on linear homomorphic hash and secret sharing(EVA-LHHSS). Firstly, EVA-LHHSS utilised linear homomorphic hash and homomorphic commitment to achieve verifiability of the aggregation results, and ensured that the verification information communication overhead was independent of the model dimensions, while preventing the server from deceiving the user into accepting incorrect aggregation results by forging the aggregation hash. Then, based on the elliptic curve discrete logarithm problem and its homomorphism, it protected the privacy of the inputs, and ensured that the verification was correct. Then, by incorporating secret sharing it made the verification process tolerant of user dropout at any time and ensured that user dropout did not result in a reduction of verification efficiency. Finally, theoretical analysis proved the correctness, reliability and privacy of the scheme. Simulation experiments show the feasibility and efficiency of the scheme, with lower computation and communication overheads compared to the VeriFL scheme, especially in the presence of user dropout, which significantly improves the verification efficiency and has a stronger dropout tolerance.
