Enigma machine, Lap 1

I have to "write a brief report describing my observations regarding operation of the electronic model and my thoughts on Enigma machine as a symmetric cryptographic platform and the associated key exchange problem" (lab enigma). I'll attach  two files. One of them 'lab enigma' contains the requirements. It has some resources that have been read, and the other file 'lab report' contains the style of the report; you need to use the lab report file to whatever you want to write.
