Extensions starting with 4, 5, 9 or 3 can also be direct dialled:
 For extensions starting with 4: dial +64 7 838 extension.
 For extensions starting with 5: dial +64 7 858 extension.
 For extensions starting with 9: dial +64 7 837 extension.
 For extensions starting with 3: dial +64 7 2620 + the last 3 digits of the extension e.g. 3123 = +64 7 262 0123.
Paper Description
An introduction to cryptographic methods.
The first half of this paper concerns number theory. The oldest subject in mathematics, number theory is now as relevant as ever because it provides the basis of cryptography and computer security. Famous problems include Fermat’s Last Theorem, the Riemann Hypothesis and the Goldbach Conjecture. Topics covered in the paper include such gems as the distribution of primes, Gauss’s theory of quadratic equations modulo p, and the mysteries of the zetafunction.
The Cryptography half of this paper will cover the basics of both public and private key cryptosystems. We will touch on Information Theory, entropy, key exchange, trapdoor functions, R.S.A., MasseyOmura, and El Gamal.
