Explore the intricacies of cryptanalysis and collision attacks in this 27-minute conference talk from FSE 2013. Delve into David McGrew's presentation on impossible plaintext cryptanalysis and probable plaintext collision attacks of 64-bit block ciphers. Examine topics such as simple models, Bayesian analysis, expected number of blocks, and real-world implications. Investigate leaks, counter mode, and multiple known plaintext scenarios. Gain insights into more sophisticated models, target values, and reasonable attack practices. Conclude with a discussion on hybrid approaches and key takeaways in the field of cryptography and information security.
