Abstract

The invention discloses a public-verifiable linear algebra entrusted calculation system. The public-verifiable linear algebra entrusted calculation system comprises an entrusting module and a third-party verifying module. Through the mode, the private verifiability of entrusted calculation is expanded to public verifiability by the public-verifiable linear algebra entrusted calculation system disclosed by the invention, so that not only does a consignor have the verifying capability, any third party can efficiently verify results. As a result, the accidental calculation errors of a cloud-side server during cloud calculation and the malicious deception behavior of a cloud calculation service provider can be basically detected, and a matrix inversion scheme is indirectly realized through the utilization of quartic matrix multiplication. Besides, high verification efficiency is realized by pseudo-random functions having enclosed effectiveness.

Description

technical field [0001] The invention relates to the field of network systems, in particular to a publicly verifiable linear algebra entrusted computing system. Background technique [0002] With the development of cloud computing and the popularity of mobile devices, it is becoming more and more important for customers to entrust heavy computing tasks to servers with powerful computing capabilities. [0003] However, the security of cloud servers has become a key technology to be solved urgently in the development of cloud computing. The security here mainly refers to the fact that customers (or even other users) can verify the correctness of the calculation results performed by the server, that is, Verifiability, and the calculated data is kept secret from the server, that is, confidentiality. [0004] The concept of "public verifiability" was proposed by Bryan Parno et al., but there is currently no system that can study the public verifiability of linear algebra delegate...
