The invention discloses a block chain-based message encryption transmission method and device, equipment and a medium, and the method comprises the steps: obtaining a historical message identifier corresponding to a to-be-sent message from a block chain, and encrypting the to-be-sent message according to the historical message identifier to obtain an encrypted message, sending the encrypted message according to a sending address in the to-be-sent message, recording a sending process to obtain message sending information, generating a newly-added message identifier corresponding to the encrypted message, and uploading the newly-added message identifier to a block chain for storage; and if the encrypted receiving message is received, obtaining a corresponding message receiving identifier from the block chain, and decrypting the encrypted receiving message through the message receiving identifier to obtain a decrypted message. Through the method, the message identifier used for message encryption and decryption can be stored through the block chain, so that the situation that a secret key cannot be obtained is avoided, the speed of encrypting and decrypting the transmitted message is greatly increased, and the transmission efficiency and reliability of the message are improved.
Description
technical field [0001] The present invention relates to the technical field of blockchain, and in particular, to a method, device, device and medium for encrypted transmission of messages based on blockchain. Background technique [0002] With the rapid development of the Internet, the way of information transmission has also undergone great changes. Massive information is rapidly transmitted in the Internet. In order to ensure the safe transmission of information, traditional technical methods are implemented by encrypting the information, and the other party receives the encrypted information. After the information is decrypted and restored, there may be interference during the information transmission process, and the transmission of the secret key may fail or the information may be lost during the transmission process, resulting in the inability to obtain the secret key to complete the decryption of the encrypted information, resulting in the inability to transmit the inf...
