WebIt's just there so that we can use the high school algebra rules for manipulating polynomials in x .) Then, to multiply two numbers a and b, we just take their respective polynomials a [ x] and b [ x], multiply them together using the high school algebra rules (doing all the internal arithmetic modulo p ), and take the coefficients of the result.
WebNumber theory is famously completely useless. Gauss called it the queen of mathematics or the jewel of mathematics or something like that, because its only purpose is to further our understanding of itself . That said, solving number theory problems algorithmically is a good use of your time and effort. sharon dyballWebThe goal of the course is to introduce basic notions from public key cryptography (PKC) as well as basic number-theoretic methods and algorithms for cryptanalysis of protocols and schemes based on PKC.
