The StreamCipherGen.vhd file makes use of parameterized component LFSR.vhd to act as the encryption algorythm. This is very low security, but the modular design allows you to easily swap in your own algorithm to replace the LFSR. I&#39;ve added LFSR re-seeding based on last transmitted data value to make the encryption a little more secure, but it&#39;s still pretty low security. 


Basically just posting this for fun and enjoyment<#EMO_DIR#>/smile.gif

The LFSR Module...
