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....

Asymmetric Cryptography Overview

This module reviews the principles and requirements of asymmetric cryptography, which uses a pair of keys - with one party using a public key and the other using the corresponding private key or vice versa - in contrast to symmetric cryptography using a shared secret key. ...

Diffie-Hellman Key Exchange

Diffie-Hellman Key Exchange is an asymmetric cryptographic protocol for key exchange and its security is based on the computational hardness of solving a discrete logarithm problem. This module explains the discrete logarithm problem and describes the Diffie-Hellman Key Exchange protocol and its security issues, for example, against a man-in-the-middle attack. ...

Key Distribution and Management

Cryptographic schemes build on cryptographic key, which provides asymmetry between the legitimate parties and the attacker. This module describes key distribution approaches and focuses on the approach based on public-key certificates/authority and public-key infrastructure that can support large number of parties, e.g., Internet. ...

常见问题

  • Once you enroll for a Certificate, you’ll have access to all videos, quizzes, and programming assignments (if applicable). Peer review assignments can only be submitted and reviewed once your session has begun. If you choose to explore the course without purchasing, you may not be able to access certain assignments.

  • When you enroll in the course, you get access to all of the courses in the Specialization, and you earn a certificate when you complete the work. Your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile. If you only want to read and view the course content, you can audit the course for free.
