|Code||COMPGA03 (also taught as COMP3063 and COMPM063)|
|Taught By||Emiliano De Cristofaro (100%)|
|Aims||For many centuries the goal of cryptography was the protection of privacy of communications. Computers, digital communication and in particular the internet have brought an abundance of new security goals. Examples are: anonymity, authenticity, non-repudiation, authorized wiretapping (called law enforcement), and traceability. To each need corresponds security mechanisms to achieve it. The goal of the course is to make students familiar with such techniques and some of the foundations of these methods. In particular students will be confronted with a range of security objectives, different levels of security that can be achieved and some available cryptographic techniques that can be used.|
|Learning Outcomes||Students start learning how to think from an adversarial viewpoint. The goal is to become familiar with basic techniques to protect data in computer and communication environments against several different varieties of fraud.|
