| Popis: | In order to improve the security of remote transmission of multi-channel Internet of things, a new information hiding method based on symmetric encryption algorithm is proposed. This method is mainly based on the symmetric encryption algorithm, combined with the symmetric encryption algorithm and LSB least significant bit algorithm. After encrypting the long-distance transmission information of multi-channel IOT, the encrypted image carrier data is embedded into the digital image carrier data according to the LSB least significant bit algorithm, and embedded in the multi-channel The 64 bit image carrier data block of IOT long-distance transmission information is fed back to the multi-channel IOT data block, and the bit width is converted into 8-bit words to realize the final conversion word output. The long-distance transmission information is hidden through the IOT, so as to achieve the purpose of hiding the remote transmission information in the multi-channel Internet of things. Experimental analysis shows that the hidden information consumption of this method is at least 215.68 J, and the text information can still be extracted correctly when the clipping rate reaches 75%. |
