Descripción de “Asymmetric Cryptography and Key Management (Coursera)”

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.

Course 3 of 4 in the Applied Cryptography Specialization.

Syllabus

WEEK 1

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.

Graded: Asymmetric Cryptography Overview

Graded: Asymmetric Cryptography Framework

WEEK 2

RSA Algorithm

This module describes the RSA cipher algorithm from the key setup and the encryption/decryption operations to the Prime Factorization problem and the RSA security.

Graded: RSA Operations

Graded: RSA Algorithm

WEEK 3

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.

Graded: Discrete Logarithm and Primitive Root

Graded: Diffie-Hellman Key Exchange and El Gamal Encryption

WEEK 4

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.
