1.7 Introduction to Cryptography

1.7.1 Topics(s)

Symmetric Cryptography (DES, Twofish)

Public Key Cryptography

Public Key Infrastructure

Certificates

Hash Functions (MD4, MD5, SHA-1, SHA-2, SHA-3)

For integrity

For Protecting Authentication Data

Collision Resistance

Digital Signatures (Authentication)

Key Management (Creation, Exchange/Distribution)

Cryptographic Modes (Strengths and Weaknesses)

Types of Attacks (Brute Force, Chosen Plaintext, Known Plaintext, Differential and Linear Cryptanalysis, etc.)

Common Cryptographic Protocols

DES -> AES (Evolution from DES to AES)

Security Functions (Data Protection, Data Integrity, Authentication)

1.7.2 Outcome(s): Students will be able to:

____ Identify the elements of a cryptographic system
____ Describe the differences between symmetric and asymmetric algorithms
____ Describe which cryptographic protocols, tools and techniques are appropriate for a given situation
____ Describe how crypto can be used, strengths and weaknesses, modes, and the issues that must be addressed in an implementation (e.g., key management), etc
