Abstract

The invention discloses an outsourcing calculation method for matrix inversion based on elementary matrix. Under the premise of no cryptographic difficulty assumption, elementary matrices and sparse matrices with lower computational complexity are used to protect the security of input and output data and improve the outsourcing calculation. efficiency. The Monte Carlo algorithm is used to verify the correctness of the returned results, and the calculation cost of outsourcing matrix inversion calculation is reduced by adding a step decomposition design. Thus, the security of client data is improved, and the outsourcing overhead of the client is reduced. The method of the invention has the characteristics of safety, high efficiency, verifiability of results and the like.

Description

technical field [0001] The invention relates to the technical field of cloud outsourcing computing, in particular to a matrix inversion outsourcing computing method based on an elementary matrix. Background technique [0002] Since the 21st century, with the rapid development of the mobile Internet and the Internet of Things, the number of network users and mobile users has increased dramatically, the scale of data generated every day has exploded, and users are increasingly inclined to use portable smart devices (mobile phones, tablets, etc.). , computer, etc.) to process the calculation. Due to the rapid increase of data, data storage and computing tasks have become more complex, and due to the asymmetric allocation of resources, portable devices and individuals with limited computing power are stretched to face some complex computing operations. Purchasing equipment to improve computing power and increase storage space may result in waste of resources and high costs. Th...
