What pre-knowledge do you need to master before reading the book “Encryption and Decryption”?

  c++, question

I am very interested in reverse engineering. I have seen many people recommending this book online. I would like to ask what pre-knowledge I need before reading this book.

This kind of problem is more real when reading book reviews on book purchasing websites, such as Amazon, Jingdong and Dangdang. I prefer Amazon, and those who go to Amazon to buy books and comment on them should all be hardcore readers.
