Description Information Security is concerned with the protection and privacy of information in computer systems. The focus is primarily on introducing cryptography concept, algorithm and protocol in information security and applying such knowledge in the design and implementation of secure computer and network systems. The unit also addresses conventional and public key encryption, number theory and algebra and their application in public key encryption and signature. Students will learn the application of cryptography algorithm in current computer systems and information security management. This unit also provides students with the practical experience around security programming.
