Stronger Password-Based Encryption Using I/O Hardness

Sign up or log in to save this to your schedule and see who's attending!

Password-based encryption needs all the help it can get to withstand brute-force attacks. We repurpose an old idea to encrypt data so that each password guess requires processing all of the encrypted data. Then, we'll look at some use cases to see how the costs change for the attacker and defender. In a brute force attack, this can mean a large increase in attacker I/O, with little cost increase to defenders, who must process all of the data anyway.
