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.

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.

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.
