- Synopsis:
-
The lecture will set mathematical foundations of modern cryptography (RSA, El-Gamal, elliptic curve cryptography, hashing). Also, the related algorithms for primality testing (numbers sieves) and discrete logarithms will be treated.
- Requirements:

-
1. Basic notions of number theory, generators of random numbers and random primes.
2. A review of basic cryptosystems (RSA, El-Gamal).
3. Rabin-Miller test for generating random primes.
4. Using Euler's totient function for factorisation, generator of Z_m^*.
5. Hashing and message authentication.
6. Subexponential algorithms for factorisation and discrete logarithm.
7. Basic ideas of quadratic sieve.
