## 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. ...
