Abstract

The embodiment of the invention provides an asset type consistency evidence generation method and system, a transaction method and system and a transaction verification method and system. The eEquipment of thea transaction initiator generates a reference ciphertext of the target asset type; generating generates a first digital signature for a message containing the reference ciphertext and a first verification ciphertext of the transaction initiator by using the first private key, and obtaining obtains a second digital signature generated by using a second private key to a message containingthe reference ciphertext and a second verification ciphertext of the transaction receiver, and obtaining obtains asset type consistency evidence containing the first verification ciphertext, the second verification ciphertext, the reference ciphertext, the first digital signature and the second digital signature. Wherein tThe asset type consistency evidence can be used for proving that the first verification ciphertext, the second verification ciphertext and the reference ciphertext are obtained based on the same asset type. Based on this, on the premise of protecting the privacy of the transaction party, a zero-knowledge proof which can publicly verify whether the verification ciphertext corresponding to the two transaction parties is obtained based on the same asset type or not can be provided.

Description

technical field [0001] The embodiments of this specification relate to the field of information technology, and in particular to methods and systems for asset type consistency evidence generation, transaction, and transaction verification. Background technique [0002] The types of assets (such as RMB, US dollars, securities, etc.) used by entities (such as institutions, companies, etc.) to conduct business may be the entity’s commercial secrets, and privacy protection needs to be done for them to avoid disclosure to external parties (such as competitors). In addition, the disclosure of asset types may lead to the acquisition of more private information of the entity. For example, in cross-border remittance or in the supply chain, it is possible to infer the region where the entity is located through the asset type, and then infer the identity information of the entity. In order to prevent privacy leakage, the entity will upload the ciphertext of the asset type to the chain...
