VIDEO: 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 video reviews the principles of asymmetric cryptography and describe how the use of the pair of keys can provide different security properties, the popular asymmetric schemes in the RSA cipher algorithm and the Diffie-Hellman Key Exchange protocol, and talk about how and why they work to secure communications/access. Lastly, the video covers 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.
