Embodiment Construction
[0097] The software platform of the system test of the present invention is mainly based on these two parts of Visual Studio-OPENSSL (cipher part) and MATLAB (information transmitting and receiving part). Among them, computer 1 simulates the plaintext encryption process, ciphertext decryption process, signature information generation process, and signature information authentication process based on Visual Studio-OPENSSL, and computer 2 simulates the noise-adding channel based on MATLAB and the information of the transmitter and receiver The process is simulated. In the experiment, other relevant parameters are shown in Table 10.
