Efficient Implementation of a Practical Leakage-Resilient ID Scheme


Instead of viewing cryptographic algorithms as simple black-boxes, leakage-resilient cryptography accepts that certain traditionally secret parts of the algorithm will be available to the attacker through side channel attacks and aims to ensure the security of these algorithms in the presence of such leakage. We present a leakage resilient identification scheme based on the continuous memory leakage model, which assumes that the leakage of information is unrestricted in time and space. We design a three message sigma protocol, secure under the symmetric external diffie-hellman (SXDH) assumption, using pairings-based elliptic curve cryptography.

This is joint work with Chiraag Juvekar, Utsav Banerjee, Yael Kalai, and Anantha Chandrakasan.

I will present this talk such that minimal background with cryptography is necessary.
