Another part is to use the unique attributes of the blockchain transaction for covert communication, such as transaction address, amount, etc. The method has good safety concealment, but has the problems of low transmission efficiency and the like.

But has the problems of low embedding rate, uncontrollable communication security level and the like. And a transmission method (CCBRSN) for carrying out hidden information under the chain upper chain is also researched, wherein in a self-built bitcoin test network, information is firstly embedded into a transaction address, index information and transaction address ID are transmitted through a file under the chain, the embedding rate is improved, and the safety is improved to a certain extent. Although the overall embedding rate is high, only the channel transmitted on the chain is not fully utilized, and the security level of communication is uncontrollable.
Therefore, the method combines the storage field and the transaction address to design a controllable security level covert communication method based on the bit coin address confusion ciphertext. The scheme not only has controllable safety, but also improves the transmission efficiency to a great extent.

Example 2
Referring to fig. 5 to 7, in another embodiment of the present invention, unlike the first embodiment, a verification test of a controllable security level covert communication method based on a bit coin address confusion ciphertext is provided, and a technical effect adopted in the method is verified and explained.
The performance of the 4 methods was compared and analyzed in four ways in this example, and the results are shown in Table 1.
First, in terms of embedding rate, block is the amount of information that each address carries in 1bit binary. The V-BLOCCE method adopts a special address generation method, the information quantity carried by the generated address can be controlled, but in the experiment of the V-BLOCCE, the address is optimally generated by comprehensively considering that 3 characters are selected from the information, and each address carries at least the information quantity coded by the 3byte Base58 and is higher than the information quantity carried by the randomly generated address. The Hash-based MBE method embeds ciphertext information and confusion information into Value fields, and the average embedding rate is 28.12bit/t through experimental calculation. In the method (csccb), information is converted into information encoded by Base58 and then randomly embedded in a chain-generated address set, as shown in fig. 5, R is the matching rate of ciphertext information, and it is known that the average ciphertext matching rate is 45%, the embedding rate is (r×el) byte/address, and EL is the length of ciphertext encoded by Base 58. Experiments prove that the embedding rate (R) byte/address increases with the increase of the ciphertext length (EL).
Second, in terms of information transmission efficiency, the information transmission efficiency is related to the embedding rate. In the block method, the information needs to be encrypted and binary coded, and each bit can be embedded into one address, so that the transmission efficiency is low. The CCBRSN method embeds the information into the randomly generated address, the index set is transmitted through the files under the chain, the embedment rate is improved, and the transmission efficiency is further improved. The V-block method uses Base58 to encode embedded information and transmits index information through a storage field, thereby greatly improving transmission efficiency compared with the block method. As shown in FIG. 6, the CSLCCB method embeds and confuses ciphertext through an address, and the index and the confused ciphertext are directly filled into a storage field for transmission, thereby greatly improving transmission efficiency. Assuming that 100 bytes of information is transmitted, the block method requires 1600 to 1800 transactions, the V-block method requires 20 to 25 transactions, and as shown in fig. 7, the CSLCCB method requires 4 transactions when s=0 and requires 11 transactions when s=4.
Third, the security of the BLOCCE, V-BLOCCE, CCBRSN and Hash-based MBE methods is not controllable in terms of whether the security is controllable. The security of the csccb method is related to the security level set by the sender. Thus, only the security of the csccb method is controllable.
Finally, in terms of whether the address number is controllable, in the BLOCCE, V-BLOCCE and CCBRSN methods, the address is continuously generated through carrying ciphertext information by the address until all information on the ciphertext is embedded by the address, and the address number cannot be effectively controlled. In the CSLCCB method, the number of transaction Input address sets is controlled according to the controllable security level.
Table 1: performance comparison of the present invention with other methods
