I have seen an episode (TOS or TNS?) where they say the Cylons can crack
any Colonial encryption code and send viral code on any Colonial computer
system so I was thinking they can do it if the Colonial security was based
on keys based on binary polynomials. Then I found out about the Enigma
machine the Nazis used in WWII had worked and about the different levels
the encryption is done on and is not 100% machine-dependent. The question
is assuming the Cylons are that highly advanced as portrayed would they still
be able to crack Colonial messages if they were to use and Enigma machine
or a software simulation of one? The next question is how to set up and then
maintain a Colonial security system that keeps Cylon intrusions out? Check out
