Embodiment 1
[0031] see figure 1 , the present invention provides a technical solution: a data covert transmission method based on a block chain network, including the following process:
[0032] 1. Out-of-chain key exchange phase: Before the data is transmitted in a concealed manner, the sender and receiver must exchange their respective public keys in advance. This process will be implemented in an off-chain communication channel, requiring a direct exchange of information between the receiver and the sender. To reduce the risk of off-chain communications being monitored by potential adversaries, the number of off-chain key exchanges must be kept to a minimum. In this scheme, the sender and the receiver only need one key exchange to safely complete multiple data transmissions. Off-chain key exchange can be implemented using existing technologies. For example, data transmission technology based on SSL encryption.
[0033] 2. Concealed data construction stage: In this stage, the sender...
