Title:
DATA COMMUNICATION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/240623
Kind Code:
A1
Abstract:
The present disclosure relates to the field of data communications. Specifically provided are a data communication method and apparatus. The data communication method is applied to a device end, and comprises: generating plaintext data to be transmitted; generating an encryption key according to a token code, which is generated by means of a device end in the current network distribution period; and encrypting the plaintext data by using the encryption key, so as to obtain ciphertext data, and sending the ciphertext data to a peer device. In the embodiments of the present disclosure, a token code is dynamically and randomly generated on the basis of a network distribution period of a device end, such that the randomness and the dynamic change of an encryption key are maintained, thereby improving the data security. Moreover, key isolation between different devices is protected, such that even if a key on one device end is cracked, the data security of other device ends cannot be compromised.
