    Man, that's the super coolest explannation of groups I've ever seen. The monsters group is hilarious! Thank you! I'll subscribe and will wait another 2 years for the next video.

    Definitely interested in the prime power fields. It's impossible to find any online explainer for them that's "accessible" to mortals - people with less than graduate-level math background - I say this as a "mortal" myself... 😭

    Nitpick: additive and multiplicative identities need not be distinct, as shown by the existence of the trivial field {0}. Exercise for the reader: prove that the two identities are indeed distinct for all other (nontrivial) fields.

    I don't get how you get a = y_1 - b * x_1, it isn't clicking

    • @CryptoClear
      @CryptoClear  3 года назад

      We know that f(x_1) = y_1, which means that a + b * x_1 = y_1. Have a look here for more concrete examples: www.mathsisfun.com/algebra/line-equation-2points.html

      That depends a lot on what you want to learn more about. For more properties of fields and mathematical proofs, the Stanford course notes linked in the description are quite clean: web.stanford.edu/~aaronlan/assets/finite-fields.pdf. For practical use in crypto, make a Google search for "diffie hellman key exchange" or "ElGamal encryption" (using groups, not fields). Also, any good cryptography course (book) will have a lot on this topic!

      @@waqasaps To learn theory, I would recommend searching Google Scholar, often there are overview or introduction-level articles/books: scholar.google.com/scholar?q=introduction+elliptic+curve+cryptography. For implementation, this looks like a great start (if you're ok with python): www.johannes-bauer.com/compsci/ecc. See especially the examples using Sage library which provides most of the common operations.
