Abstract

The specification discloses a data transmission method, a data transmission device, a storage medium and an electronic device, and firstly, an encryption key created by a key management system is received. And secondly, encrypting the blockchain private key of the user according to the encryption key to obtain encrypted data. And then, storing the encrypted data into a bridging system to complete the deployment of the bridging system. And then, when receiving a service request aiming at the user, sending an indication message to the bridging system so that the bridging system obtains a decryption key corresponding to the encryption key from the key management system based on the indication message, and decrypting the encrypted data through the decryption key to obtain a blockchain private key of the user. And finally, executing the block chain service corresponding to the service request according to the block chain private key of the user through the bridging system. The method can avoid the risk of revealing the blockchain private key of the user when the blockchain private key of the user in the plaintext is stored in the bridging system, and improves the safety of the blockchain private key of the user.
