## 课程概述

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....

Some annoying errors in quizes, and I wish there was something more about elliptic curves, but otherwise good course.

Excellent to the point with good references

Solid course and pretty good introduction to the topics of asymmetric cryptography. More time spent on the modular arithmetic of RSA encryption as well as the Discrete Logarithm math would have been good for strong understanding of what was going on. It was hard to understand those core topic without many external references.

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.
