Modern Cryptography - Secrecy in the Digital Age

Professor Thomas Erlebach

The Internet makes it easy to communicate and access information, but sometimes it is important that we can keep some information confidential, for example when we send credit card numbers or passwords. In this lecture, we discuss the principles of modern cryptography and how they can be used to keep data secret from anyone except the intended receiver. We will also discuss visual cryptography, which can hide information in images that look completely random but can be decrypted by the human eye if the correct key is used.
