Embodiment Construction

[0018] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0019] Based on the above analysis, it can be seen that the confidentiality of the existing blockchain network communication is not strong, and the security of the communication cannot be guaranteed. In order to solve this technical problem, the present invention introduces the public key certificate technology. Since the public key certificate technology is not It is necessary to maintain the directory containing the name and public key, so it is a relatively safe public key distribution method. In the present invention, the publ...

Abstract

The invention provides an encryption communication method and system for a blockchain node, wherein the method comprises the following steps: firstly, joining a participating node of a blockchain network, using a first signature private key of the participating node to sign a first user identifier and a first signature public key of the participating node, transmitting a first joining broadcast message to the blockchain network after stamping a timestamp via a timestamp server; analyzing the first joining broadcast message to obtain the first user identifier and the first signature public keyvia a mining node; carrying out validity verification on the participating node according to the first signature public key; generating a first encryption private key of the participating node via a supervising node according to a main key, a public parameter and a first user identifier stored via the local node; and carrying out safety communication based on the first user identifier and the first encryption private key via the participating node and the target node. Thus, the communication efficiency is improved on the basis of ensuring the communication safety of the blockchain network.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to an encrypted communication method and system for blockchain nodes. Background technique [0002] Blockchain technology has gradually become known with the emergence of Bitcoin. There is no central node in the blockchain network, and all nodes have equal status. The transaction data in the blockchain network is packaged and written into blocks by using consensus mechanisms such as workload proof and equity proof. In this decentralized network, all nodes keep data backups of the entire network. The consensus mechanism adopted by the blockchain guarantees the authenticity and effectiveness of information transmission on untrusted channels. [0003] However, based on the operation mechanism of the blockchain, even if it can guarantee that the data is tampered with during transmission, it can also prevent nodes from being attacked by denial of service. Transaction inf...
