Title:
DATA TRANSMISSION METHOD AND RELATED DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/142038
Kind Code:
A1
Abstract:
The present application relates to security protection. Provided are a data transmission method and a related device. The method comprises: receiving a transmission feedback packet, and extracting a first public key from the transmission feedback packet; generating a second public key and a private key; performing encryption processing on the second public key by using the first public key, so as to obtain a public key ciphertext; sending the public key ciphertext to a server, and receiving a ciphertext feedback packet; extracting a key ciphertext from the ciphertext feedback packet, and decrypting the key ciphertext by using the private key, so as to obtain a target key; acquiring data to be transmitted, and performing, by using the target key, encryption processing on the data to be transmitted, so as to obtain a target ciphertext; and transmitting the target ciphertext to the server. By means of the present application, the data transmission speed can be improved on the premise of ensuring the data transmission security. In addition, the present application further relates to a blockchain technology, and a target ciphertext can be stored in a blockchain.
