The 2002 International Symposium on Information Systems and Engineering (ISE'2002)
Title: Computer And Network
Security
The proliferation of computers and communication networks has resulted in the ubiquity of computers in a wide variety of applications. In several applications, the data which is processed and transmitted is valuable, critical, and strategic. However computers are vulnerable for attacks from various sources such as viruses, worms, hackers, and electronic eavesdroppers, which is detrimental to the smooth operations of the applications. This calls for security mechanisms that allow safe, uninterrupted, and secure operations of computers and networks.
This tutorial is intended to give a good overview of the principles and practices of various aspects of computer and network security. The tutorial’s plan is as follows:
1. Introduction to Computer Security.
Security attacks; Security services; Network security 10 Minutes
2. Conventional Encryption.
Block ciphers, DES (Data Encryption Standard);
IDEA; AES. 30 Minutes
3. Public-Key Encryption.
Public-key cryptosystems; RSA algorithm; 20 Minutes
Diffie – Hellman key exchange
4. Key Exchange and Key Management.
Key exchange using conventional and public key 30 Minutes
Schemes; Key exchange protocols; Digital certificates.
5. Message Authentication and Hash Functions.
Authentication codes; Hash functions; 30 Minutes
Digital signatures; Authentication protocols
6. Network Security.
Kerberos; Electronic mail security (PGP); Web security; 30 Minutes
Secure Electronic Transactions (SET).
7. System Security.
Intruders, viruses, and worms; Firewalls. 30 Minutes
This tutorial enables the participant to:
* get a good overview of various aspects of computer security.
* understand the major issues in computer security.
* get an insight into several key techniques at different levels of security.
* understand mechanisms in encryption, key management and authentication.
