Embodiment Construction

[0044] In order to enable those skilled in the art to better understand the technical solutions of the present disclosure, the present disclosure will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0045]Wherein, the terms used in the embodiments of the present disclosure are only for the purpose of describing specific embodiments, and are not intended to limit the present disclosure. As used in the examples of this disclosure and the appended claims, the singular forms "a", "said" and "the" are also intended to include the plural forms unless the context clearly dictates otherwise.

[0046] At present, the research on the blockchain is more focused on the consensus mechanism and the digital asset management level of the virtual currency. There are few practical applications, and most of them are still in the theoretical research stage. Currently, encryption and authentication methods are usually used for communication in ...

Abstract

The invention provides a multi-authentication encryption method and system based on a block chain, electronic equipment and a medium. The method comprises the steps that: an auditing node allocates public and private key pairs, timestamps and random numbers to user nodes; a sending node sends the identity information and the random number thereof to the authentication node; if the authentication node passes the authentication, symmetric key encryption is carried out on the random number of a receiving node, the obtained symmetric encrypted random number is sent to the sending node, and a symmetric key is sent to the receiving node; the sending node encrypts the public key hash value, the timestamp and the symmetric encryption random number to generate a digital certificate, and sends the digital certificate to the receiving node; the receiving node carries out verification after decryption, and the symmetric encryption random number verification comprises the following steps: decrypting the symmetric encryption random number through a symmetric secret key, and carrying out XOR operation on a result and a random number corresponding to the result to verify the legality of the sending node; and if so, session connection is established. According to the technical scheme, the legality of the identity of the sender is verified through multiple authentication, and safety is guaranteed.

Description

technical field [0001] The present disclosure relates to the technical field of blockchain, and in particular to a blockchain-based multi-authentication encryption method, a blockchain-based multi-authentication encryption system, an electronic device, and a computer-readable storage medium. Background technique [0002] The blockchain network has received widespread attention due to its characteristics of decentralization, distributed storage, time stamps, and non-tampering. However, current research on data exchange, identity authentication, etc. is mainly focused on improving encryption algorithms. The concept of the chain network, but did not make too much change to the way of user identity authentication, considering the robustness of the network and the possible multi-chain phenomenon, there are still greater risks in the authentication process; the current identity authentication uses The method is: when the network node user uploads the business data to the blockchai...
