Interactive zero knowledge proof method and device, computer equipment and storage medium

Abstract

The invention relates to an interactive zero knowledge proof method and device, computer equipment and a storage medium. The method comprises the following steps: converting the resource transfer datainto zero knowledge proof; obtaining computer integrity language data corresponding to the zero knowledge proof; converting the computer integrity language data into a polynomial constraint form; performing a low-degree test on the linear combinatorial polynomial based on an FRI protocol; and sending low-degree test data to the verification node, verifying whether the maximum degree of the linearcombinatorial polynomial is smaller than a preset value or not by the verification node according to the low-degree test data, and judging that the resource transfer is valid when receiving a certification acceptance message fed back by the verification node. In the whole process, a third party does not need to set public parameters, the content needing to be proved is converted into a linear combinatorial polynomial based on the FRI protocol to carry out a low-degree test process, the third party is prevented from being disgusted, and the zero-knowledge proof safety is remarkably improved.

Description

technical field [0001] The present application relates to the technical field of computer encryption, in particular to an interactive zero-knowledge proof method, device, computer equipment and storage medium. Background technique [0002] The current society is in the information age, and the application of cryptography is essential to solve various security problems. At present, cryptography has been widely used in network, communication, payment and other fields, and it is closely related to human life. It can be said that cryptography is one of the core technologies to solve modern information security technology. In transfer networks (such as transaction networks, payment networks, etc.), cryptography is even more important. [0003] In the traditional resource transfer network, the resource transferor may be anonymous or a temporary identity assigned by the network. All resource transfer information made by the identity on the resource transfer network is transparent,...

Problems solved by technology

[0004] Although the zero-knowledge proof technology has the above-mentioned advantages, it also has defects. When the computer network applies the zero-knowledge proof technology, it needs to rely on a third party to complete the setting of public parameters. If the third party does evil, it will not be possible to establish a reliable zero-knowledge proof. The risk of resource transfer in the entire resource transfer network
