Discussion Overview

The discussion revolves around pursuing a major in cryptography, with a focus on relevant coursework such as number theory, probability, and algebra. Participants share insights on educational paths, military experience, and resources for learning about cryptography.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant expresses interest in majoring in cryptography and seeks additional course recommendations beyond those suggested by a professor and a student from MIT.
  • Another participant suggests a career path with the NSA after college.
  • A different participant shares plans to join the CIA and gain cryptography experience through military service, specifically in the Army Rangers' engaged intel group.
  • There is a request for clarification about the Army Rangers' engaged intel group.
  • One participant proposes that a math major could be a viable alternative to a cryptography major, emphasizing on-the-job training.
  • Another participant argues that military service could provide a faster and better educational experience in math, while explaining the nature of the Army Rangers' engaged intel group.
  • A suggestion is made for the original poster to provide more background information to enhance the discussion.
  • Additional courses in computing, such as Analysis of Algorithms and Complexity, are recommended for a comprehensive understanding of cryptography.
  • A participant shares a link to the "Handbook of Applied Cryptography" and notes its relevance for foundational math knowledge.
  • One participant mentions starting to read the handbook but expresses unfamiliarity with certain mathematical symbols.
  • Quantum cryptography is introduced as an interesting field that may have military applications, with a reference to the concepts of Alice and Bob sharing Qubits.
  • A participant discusses reading "The Book of Numbers" by Conway and Guy, which is aimed at those without advanced math backgrounds, and seeks comments on the book.

Areas of Agreement / Disagreement

Participants express a variety of perspectives on educational paths and resources for cryptography, with no clear consensus on the best approach or specific recommendations.

Contextual Notes

Some participants mention the need for additional computing courses, and there are references to specific military roles and experiences that may influence educational choices. The discussion includes varying levels of familiarity with mathematical concepts relevant to cryptography.

I'm interested in doing cryptography as a major, and I've talked to a proffesor from MIT, and a student of Professor Rivest about courses to take, they included: number theory, probability, abstract algebra, and linear algebra.

I am wondering if anyone has anything to add. Also for cheap textbooks and colleges, other than MIT that have reknown cryptography courses.
 
Physics news on Phys.org
Good luck and you should work for the NSA once you are done with college :)
 
I'm actualy interested in joining the CIA, after high school I'm going to join the Army Rangers' engaged intel group, and hopefully get some cryptography experience there to boost my resume for getting into MIT.

Army Rangers' engaged intel group

what is that?
 
You could just go for a math major, and apply, aiming to get training on the job.
 
true, but in the military i can get a degree in math, far better, faster, and from better proffessors if i went beforehand.

also the army rangers engaged intel group - is similar to going undercover to find where, like for our current iraqi war, to find where terrorist locations are. Although usualy with the rangers its not too in depth past just finding basic camp sites, COG is the one that will usualy be floating around in a wig and beard actualy living that life, rangers will more so just make a simple contact usualy without a disguise or anything.
 
You know you could get a lot more out of this thread if you provided a little more background about yourself.

You'll need courses in computing as well - such as Analysis of Algorithms, Numerical Methods, Computability, Complexity, etc.
 
if i had much background in it, i would have stated such, but since i was asking for courses on the subject it shouldn't matter what's been stated.

so any advice is appreciated, along with textbook referances

Handbook of Applied Cryptography, by Menzies, van Oorschot, and Vanstone.

This is a quick and dirty overview, though a few years old. Especially relevant to you would be chapter 2, which gives a rundown of the math you'd need to know to read this book (just statements of results, no proofs).

yes i have actualy just recently started reading over that, since i haven't gotten into any calc or abstract algebra i wasnt aware of some of the differint math signs like XOR, and the like, thanks for the referance though

Quantum Mechanics

The field of quantum cryptogrophy is pretty interesting and is sure to play a big role in the military. If you google it you coule be reading about Alice and Bob sharing Qubits and that damn eve trying to listen in.

alsoright now I am reading a book called, "The book of Numbers" written by Conway and Guy which is about number theories, it says its geraed towards people without a lot of advanced math backgrounds. Does anyone have a comment on this book?
