| Abstract: | The simulation method of stream ciphers coding system by Simulink is proposed in this paper.According to the principles of gen- erating pseudorandom sequences based on feedback shift register,Simulink memory modules are used to simulate the shift register,besides, modules such as Logical Operator and Switch are employed together to construct the simulating models of key sequence generators.In addi- tion,subsystem technology is adopted to design the eneryption and decryption system simulating models.The prop... |
