![]() ![]() Any assistance on this would be appreciated. I'd hope to keep the enable input because it will be useful in other modules that will be based on the LFSR. ![]() If CLK = '1' and CLK'event and EN = '1' then I was wondering if there is a way to access the current contents of the D flip flops? I have defined my D flip flop as follows: library IEEE The issue that I'm having is that every subsequent key is going to be a shifted version of the current contents of the D flip flops. Hence, I'd have an initial value (8 bits) fed in as my input and then a new key would be generated every time a "push" signal is sent. My overall goal is to create a unique key for every input using a LFSR (linear feedback shift register). ![]() Obviously, an important component in the design of the encryption is the key. I have been attempting to design a data encryption circuit using D flip flops. I am fairly new to the VHDL language and I will admit that I primarily use it for educational purposes. ![]()
