E-commerce has made cryptography a cornerstone of modern information systems security. Cryptography is one of the 10 domains required for the CISSP, and is a core component of all other recognized information security certifications. Surprisingly, it is the least understood of the information security disciplines. This course focuses on the terminology and concepts needed to understand how cryptographic techniques are used to protect sensitive information. Topics include: Advanced Encryption Standard (AES), the Secure Hash Algorithm (SHA), Digital Signatures and Message Authentication Codes, Diffie-Hellman Key Exchange, public-key infrastructure (PKI), secure sockets layer (SSL), and IPsec among others. Lecture and reading materials are reinforced by hands-on experimentation with cryptographic software tools. Internet resources are used to tie the course material to current technology trends. No programming experience or advanced mathematical skills are required for this course. Prerequisites: ICT 4605.
