The most interesting deatil in this section would be about groups in encryption. I admit that I have never though of it possible that using two levels of encryption was the same as using on level with only one key. It was interesting to look at crypto-analysis from another angle.
The hardest part of the chapter to understand was the groups. Like other sections of the chapter it wasn't very hard (especially since I have already studied this algorithm in my Computer Security class.) Following the proof was the strangest part. The whole thing with the remainder and dividing mq still doesn't make sense to me.
