Zero-knowledge proof data interaction method, node and equipment

Abstract

The embodiment of the invention provides a zero-knowledge proof data interaction method, which is used for a trust challenge node and comprises the following steps of sending a zero-knowledge challenge request to a trust challenged node, wherein the challenge request comprises a random number and specified position data, so that the trusted challenged node signs the data of the specified positionby using a trusted platform module (TPM) of the trusted challenged node and the random number to obtain specified position signature data; receiving the specified position signature data sent by the trusted challenged node, and a measurement log ML and an AIK certificate recorded by the trusted platform module TPM; verifying whether the trust challenge node verifies that the specified position signature data and the measurement log ML recorded by the trusted platform module TPM are consistent with the AIK certificate or not; and according to the verification result, determining whether the trusted challenged node is trusted or not, so as to determine whether to transmit the (pk, vk) in the zero-knowledge verification application stored in the TEE security area to the trusted challenged node or not.

Description

technical field [0001] The embodiment of the present invention relates to the field of information security technology, and in particular to a zero-knowledge proof data interaction method, node, and device. Background technique [0002] Bitcoin does have a certain degree of anonymity, but the anonymity of Bitcoin is not impeccable. As we all know, due to the openness and traceability of the blockchain ledger, anyone can follow through the public information of the Bitcoin blockchain browser to find out all the Bitcoin accounts that have a relationship with it. Anyone who enters a wallet address can find out all the transaction details (amount, quantity, time, where the money is received from, and where it is transferred to) that occurred at this address, resulting in personal privacy disclosure. Anonymous currency makes it impossible for casual people not related to the transaction to spy on the specific information of the transaction: such as the size of the transaction am...
