Abstract

Abstract

En 中文
In this letter, the problem of distributed Secure Batch Matrix Multiplication (SBMM) is studied, where a user wishes to compute the pairwise products of two batches of massive matrices A and B generated by two external source nodes, with the aid of N distributed servers. The security for data matrices A (resp. B) is guaranteed against any group of up to X-A (resp. X-B) colluding servers. As a result, a computation strategy is presented to characterize the trade-off between recovery threshold, system cost and system complexity, based on grouping Lagrange encoding, which unifies and improves the previous strategies for SBMM.
