Cryptography, Security, and the Internet
 

Speaker: Jeffrey Ehme (Spelman College)

It has become very common for people to transmit highly confidential information over the public forum that is known as the internet. People routinely use credit cards to make online purchases and this is (relatively) safe. In this short course we will look at the mathematics of public key cryptography that makes this possible. More specifically, we will consider the Diffie-Hellman key exchange, RSA and ElGamal, the Miller-Rabin algorithm for finding large primes, and some elliptic curve versions of these topics. No previous experience with any of the mentioned topics is assumed.
