Training for every cybersecurity role. Delivered how you learn best.

What is Diffie-Hellman key exchange? Or quantum key cryptography? This course will answer all of your questions about public key infrastructure. Beginning with in-depth definitions of terms (including Certificate Authority, Registration Authority and Certificate Repository), this course takes a close look at public key infrastructure components, PKI certificates, key management and key exchange. Everything from an explanation of an X.509 digital certificate to the dangers of software-based key storage, all in four videos.

Public Key Infrastructure is what makes digital signatures and asymmetric cryptography usable in the real world. This course describes how PKI works, the roles and responsibilities of the parties involved, and some of the fundamental assumptions of PKI and their impacts on the security of the system.
