Semester I, 2005-2006 (Wednesdays 6.30 pm - 8.30 pm, LT33)
Last update: Monday, 07-Nov-2005 17:08:58 SGT
Lecturer: Mohan S Kankanhalli
Aims and Objectives:
This course aims to develop a critical appreciation of the fundamental cryptographic techniques and a solid understanding of data security issues.
Brief Description:
With the widespread use of computers and internet as well as the rapid spread of electronic commerce, computer security has become very important. This course introduces the main cryptographic methods for communication and computer system security. The topics include: symmetric ciphers, public key cryptography, stream ciphers and block ciphers, digital signatures, message authentication, operating system security, access control, entry authentication and key distribution mechanisms, network security and privacy. The course will also cover international standards that implement the concepts.

The main textbook for the course will be:
It is not necessary to buy Gollman's book. I will be covering some parts of operating systems security from Gollman's book. I will provide any supplementary material if required. For each lecture, I will email the slides to the whole class a few days before the day of that lecture. So please do subscribe to the class mailing list. In order to subscribe to the class mailing list, please send an email to "cs5231-l-request@comp.nus.edu.sg" with the word "subscribe" in the subject line and with no message.
