The passage that stuck out to me the most from the novel was Marcus’ description of the use and benefits of cryptography from page 57. Even though it’s at the beginning of the book, this passage gets to the core of how cryptography works for us today. Cryptography is used by everyone because is as accessible to everyone. Thankfully, our government does not have a monopoly on cryptography; “the math behind crypto is good and solid, and you and me get access to the same crypto that banks and the National Security Agency use” (Westerfeld 57). Because it is so widely used, we can be sure of its effectiveness.
The quote continues to discuss how cryptography is useful to us today. Even if we do not have anything to hide, “there’s something really liberating about having some corner of your life that’s yours, that no one gets to see except you.” This reminds me of the article I read regarding the actions of the National Security Agency and invasion of civilian privacy due to bulk data collection. The fact that personal information as well as government intelligence is encrypted using the same means shows that the government has access to all of our information as well. This is not a bad thing; access to this information can be useful in ensuring peace. The question still remains: when does government access of individual data cross the line from protection to trespassing?
