MD- $$\mathcal {VC}_{Matrix}$$ VC M a t r i x : An Efficient Scheme for Publicly Verifiable Computation of Outsourced Matrix Multiplication

摘要: Cloud service provider that is equipped with tremendous resources enables the terminals constrained to perform outsourced query or computation on large scale data. Security challenges are always research hotspots in community. In this paper, we investigate problem of publicly verifiable matrix multiplication. However, state-of-the-art scheme, a number computationally expensive operations adopted achieve goal public verification. Thus, scheme works inefficiently actually due fact most time spent verification-related computing. To lower cost, propose an efficient for verification The two-dimensional transformed into one-dimensional vector, which retains computing ability and used as substitute subsequent work. security analysis demonstrates proposed outsourcing performance shows running efficiency scheme.
