Embodiment
[0033] This embodiment provides a data transmission method based on interleaving and fragmentation. In the data transmission method based on interleaving and fragmentation, the transmitting end maps the transmitted original data into several fragmented data and sends them to the receiving end through an interleaving matrix. The receiving end decodes the received sliced data into the original data by using the interleaving matrix.
[0034] Preferably, the interleaving matrix is generated by the sending end, and the ciphertext of the interleaving matrix is transmitted to the receiving end in an encrypted manner; the receiving end obtains the plaintext of the interleaving matrix through decryption.
[0035] The sending end and receiving end described in this embodiment are physical devices in network communication devices, including but not limited to servers, Internet of Things devices, and handheld terminals.
