Cybersecurity Rule 6: Use Cryptography Correctly

This talk explores some of the key mathematical concepts used in cybersecurity.�� Cryptography is one obvious example where mathematics plays a critical role in cybersecurity. However, this talk is not centered around developing new cryptographic algorithms.�� Instead, the talk explores how mathematical concepts are fundamental to all of cybersecurity, regardless
of whether one is working in cryptanalysis or writing secure software.�� The talk tile draws from a well known paper on the “Top Ten Software Design Flaws” where flaw number 6 is the failure to use cryptography correctly.�� The flaw is not that the cryptographic algorithms themselves are broken, but rather the flaw comes from misunderstanding their properties and using cryptographic tools incorrectly.�� In the talk, we will explore what it means to use cryptography correctly as well as explore other aspects where mathematics and cybersecurity intersect.
