A Secure Consensus Method Based on Delegated Proof-of-Stake Protocol in Heterogeneous Environment

Abstract

The invention discloses a security consensus method based on a delegated share certification protocol in a heterogeneous environment. In the present invention, the node registers to obtain the common node, checks its rights and interests, and obtains the rights holder node. The registered node scans to obtain the list of stakeholder nodes and the list of witness candidate nodes. Query the address of the stakeholder node and get confirmation of sending a blank vote. Add data items, get votes. Stakeholder nodes vote to select a node in the list of witness candidate nodes, and as a result, one of the nodes is selected. After the stake holder node generates a signature, it sends the signature and votes to the counting node. By processing invalid votes, the vote counting node obtains and publishes the results of the vote counting, and publishes the votes and signatures, and copies of the votes and signatures. Get blocks to form a blockchain. The invention realizes authentication, secrecy, anonymity, fairness, anti-threat, verifiability, and no receipt, and achieves certain security and privacy requirements.

Description

technical field [0001] The invention belongs to the technical field of user communication security, and in particular relates to a security consensus method based on an entrusted share certification protocol in a heterogeneous environment. Background technique [0002] Public key cryptography (Public Key Infrastructure, PKI) is the main means of deploying traditional public key cryptography (Public Key Cryptography, PKC). The binding relationship is obtained in the form of a digital certificate, and the certificate is issued by a trusted certificate authority (Certificate Authority, CA) for the user. The certificate authority first verifies the identity of the user, and then issues the certificate after confirming the authenticity. [0003] Based on identity based cryptography (IBC), in order to simplify the problem of certificate management, Shamir first proposed the concept of identity-based public key cryptography (ID-PKC) in 1984, pointing out that the authenticity of k...

AI Technical Summary

Problems solved by technology

[0004] Before 2010, users communicated based on the same cryptographic system, based on the public key infrastructure environment, or based on the identity encryption environment, or based on the certificateless encryption environment, but with the development of communication technology, communication parties around the world use different passwords The system, therefore, only communicates in one environment and can no longer meet the user's communication requirements

However, there are problems of bribery and inactive voting in the existing DPoS consensus agreement
