Henry Corrigan-Gibbs: 2016 Security Workshop


Monday, April 11, 2016
Location: McCaw Hall, Arrillaga Alumni Center

"Space-Hard Functions for Password Hashing"



In this talk, I will introduce the problem of password hashing and will explain the reasons to prefer space-hard password hashing functions over conventional cryptographic hashes. Next, I will present the design and analysis of the Balloon hash functions, a new family of space-hard hash functions that

require a certain amount working space to compute efficiently, avoid certain important side-channel attacks, and are fast enough for real-world use.

Finally, I will discuss recent results on space-hard hashing in the parallel setting and related open problems.

Joint work with: Dan Boneh and Stuart Schechter.
