Abstract
This application discloses a data communication method implemented at an electronic device. The electronic device obtains a sequence of data packets. Each data packet complies with a first data format corresponding to a network access protocol and comprises a respective header that further includes a data length field for specifying a length of the respective data packet. Data are then assigned to the data length fields of the sequence of data packets according to a second data format. The electronic device encrypts the sequence of data packets including the assigned data. The encrypted data packets are then sent to a receiver device that is communicatively coupled to the electronic device via a wireless network. The receiver device is configured to retrieve the assigned data from the data length fields of the data packets according to the first and second data formats and perform operations in accordance with the retrieved data.
