Embodiment Construction

[0059] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

[0060] Blockchain (Block chain) is a new application model of computer technologies such as distributed data storage, peer-to-peer transmission (P2P, Peer To Peer), consensus mechanism, and encryption algorithm. Blockchain is essentially a decentralized database, which is a series of data blocks associated with cryptographic methods. Each data block contains one or more transaction information, which is used to verify the validity of its information ( anti-counterfeiting) and generate the n...

Abstract

The embodiment of the invention discloses a digital signature processing method and device, computer equipment and a storage medium. The digital signature processing method comprises the steps that asignature node acquires consumption voucher information for a first voucher user and acquires the first digital signature of the consumption voucher information; the signature node adopts a private key of a second voucher user having an association relationship with the first voucher user to sign the consumption voucher information to obtain a second digital signature; and the signature node sendsthe consumption voucher information, the first digital signature and the second digital signature to a consensus node, instructs the consensus node to verify the first digital signature and the second digital signature, and enables the consensus node to add the consumption voucher information to the service block chain after the first digital signature and the second digital signature pass the verification. According to the invention, the security of the private key of the user can be enhanced.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a digital signature processing method, device, computer equipment and storage medium. Background technique [0002] With the development of Internet technology and the popularization of various electronic applications, more and more user transaction data have been generated, and the problem of safe storage of data has become more and more obvious. Most of the existing information security storage solutions adopt centralized security management. User transaction data is maintained by a centralized server. Once the server is attacked maliciously, user transaction data will inevitably be at risk of leakage. [0003] Blockchain technology has the characteristics of decentralization, distributed storage, time stamp, and non-tampering, which can perfectly solve the shortcomings of centralized information security storage. [0004] At present, when a certain user's user...
