Distributions Attaining Secret Key at a Rate of the Conditional Mutual Information

Explore the intricacies of cryptographic key distribution in this 27-minute lecture, focusing on distributions that achieve secret key rates equal to conditional mutual information. Delve into common information, common randomness, and conditional distributions while examining uniform block independent examples. Analyze strong necessary conditions for distributions and engage in a thought-provoking discussion on the implications for secure communication systems.
