About the Course

Welcome to Asymmetric Cryptography and Key Management! In asymmetric cryptography or public-key cryptography, the sender and the receiver use a pair of public-private keys, as opposed to the same symmetric key, and therefore their cryptographic operations are asymmetric. This course will first review the principles of asymmetric cryptography and describe how the use of the pair of keys can provide different security properties. Then, we will study the popular asymmetric schemes in the RSA cipher algorithm and the Diffie-Hellman Key Exchange protocol and learn how and why they work to secure communications/access. Lastly, we will discuss the key distribution and management for both symmetric keys and public keys and describe the important concepts in public-key distribution such as public-key authority, digital certificate, and public-key infrastructure. This course also describes some mathematical concepts, e.g., prime factorization and discrete logarithm, which become the bases for the security of asymmetric primitives, and working knowledge of discrete mathematics will be helpful for taking this course; the Symmetric Cryptography course (recommended to be taken before this course) also discusses modulo arithmetic. This course is cross-listed and is a part of the two specializations, the Applied Cryptography specialization and the Introduction to Applied Cryptography specialization....

Very good intro, particularly talking about Key Management, an usually overlooked aspect of Crypto. Professor is also super clear in his explanations. Recommended :)

Good course to learn Asymmetric Cryptography really helped me a lot to learn , suggest all to take this specialization course to build carrier in cryptography.

This course was very awesome. I learned a lot of concepts. But I think ECDSA was missed which I wanted to learn as well as the new EdDSA.

I learned / refreshed a lot during this course. The lecture has great knowledge. The english transcripts need serious amendments.

I'd love to have practical exercises usin openssl and other common cryptographic tools.

The courses in this applied cryptography specialization just get worse and worse. Symmetric Cryptography is a joke of a course. The quizzes are impossible to solve. There is no support. There is nothing but the most high-level overview of the actual cryptography and there isn't enough teaching of the mathematics. This is just the absolute worst course I have taken on Coursera.
