Welcome to Cryptography!
Cryptography is the practice and study of techniques for securing communications in the presence of third parties. You will learn how to protect information in order to ensure its integrity, confidentiality, authenticity, and non-repudiation.
You will come out with a basic understanding of cryptographic concepts and how to apply them, implement secure protocols, key management concepts, key administration and validation, and Public Key Infrastructure.
1. Apply the fundamental concepts of cryptography
2. Describe the difference between symmetric and asymmetric cryptography
3. Define the basic requirements for cryptography
4. Identify processes to support secure protocols
5. Describe the process for implementing cryptographic systems
6. Define key management concepts
7. Define Public Key Infrastructure
8. Identify processes for key administration and validation
9. Describe the implementation of secure protocols

In Creation and Distribution of Keys you will learn about truly random, random, generating a two-key encryption key set, key length, Asymmetric key length, key wrapping and key encryption keys, key distribution, key distribution centers, key storage and destruction, factors affecting risk exposure, cost of certificate replacement/revocation, key recovery, key escrow. In Secure Protocols you will learn about Authentication Header (AH), Encapsulating Security Payload (ESP), security associations, transport mode and tunnel mode, Internet Key Exchange (IKE), Secure/Multipurpose Internet Mail Extensions (S/MIME), S/MIME provides two security services, digital signatures, process for verifying a digital signature of an E-Mail message, message encryption, process for encryption of an E-Mail message, process for decrypting an E-Mail message, process of digitally signing and encrypting an E-mail message, process of decrypting an E-Mail message and verifying a digital signature, and triple-wrapped messages.
Cryptography Case Study This assignment is based on a case study that will require the student to put into practice the knowledge they have gained through the course. It requires the basic understanding of the topics and the ability to relate those topics to the real world. The objective of review is to determine whether the student has understood the concepts and has performed the necessary analysis to ensure a complete and thorough answer.
MOOCs stand for Massive Open Online Courses. These arefree online courses from universities around the world (eg. StanfordHarvardMIT) offered to anyone with an internet connection.
How do I register?

How do these MOOCs or free online courses work?
MOOCs are designed for an online audience, teaching primarily through short (5-20 min.) pre recorded video lectures, that you watch on weekly schedule when convenient for you. They also have student discussion forums, homework/assignments, and online quizzes or exams.
Ilya Rudyakcompleted this course, spending 5 hours a week on it and found the course difficulty to be medium.
Much more approachable course than those in Stanford (and even than Katz own book). Especially if you prefer top-to-bottom method. I've completed Stanford course 2 years before and it's great but now I'm really understand mechanics behind modern cryptography and all its proofs.
