Nathan: What is RSA, how does it work, what are its vulnerabilities?
So what exactly is RSA encryption? RSA, or Rivest-Shamir-Adleman, its creators, is "a public-key cryptosystem that allows us to encrypt messages between two communicating parties so that an eavesdropper who overhears the encrypted messages will not be able to decode them" (Cormen). A public-key cryptosystem also allows for a party to send a digital signature along with their message. This signature loses its validity if any bit of the message is changed which provides authentication of both the message and the sender.

Here are APA citations for several possible sources. We don't need to use all of them but any of them could be useful, especially for comparing the quantum situation with classical and post-quantum. Manin & Zilber includes discussion of both quantum logic as a broader topic, and the character of Shor's quantum algorithm for prime factorization and how it fundamentally changed the security situation for public-key systems that rely on factoring being inefficient. Aaronson has a lot of interesting and more intuitive discussions about both theory and practical problems like quantum computers and the potential dangers they pose, and separating hype from what could feasibly happen. Garey & Johnson has a long list of NP-complete problems across different areas of math and computer science that could be interesting for comparison across topics. Cormen et al, could be a good reference for parts of the classical domain, especially RSA and related public-key systems.
