TAILIEUCHUNG - Information Theory and Security

Up to this point we have seen: Classical Crypto Symmetric Crypto Asymmetric Crypto These systems have focused on issues of confidentiality: Ensuring that an adversary cannot infer the original plaintext message, or cannot learn any information about the original plaintext from the ciphertext. In today’s lecture we will put a more formal framework around the notion of what information is, and use this to provide a definition of security from an information-theoretic point of view. | Information Theory and Security Lecture Motivation Up to this point we have seen: Classical Crypto Symmetric Crypto Asymmetric Crypto These systems have focused on issues of confidentiality: Ensuring that an adversary cannot infer the original plaintext message, or cannot learn any information about the original plaintext from the ciphertext.

Lecture Outline Probability Review: Conditional Probability and Bayes Entropy: Desired properties and definition Chain Rule and conditioning Coding and Information Theory Huffman codes General source coding results Secrecy and Information Theory Probabilistic definitions of a cryptosystem Perfect Secrecy The Basic Idea Suppose we roll a 6-sided dice. Let A be the event that the number of dots is odd. Let B be the event that the number of dots is at least 3. A
