I spoke on the Significance of Random Numbers in Application Security. I started off with the practical usage of random numbers. I explained how good random number generation prevents applications from malfunctioning, increases strength of cryptographic operations which in turn increases entropy associated with the key.
I went on to explain how random numbers automate otherwise manual tasks and how it increases the security of application. Explaining the concepts of entropy and seeds I explained the level it should be reached in an application. Finally, I spoke about the various sources of random numbers.I also showed developers the simple mathematics required to calculate minimum password lengths, given the security requirements.
