Yael Kalai, researcher at Microsoft Research New England discusses how, with all the progress made in the field of cryptography, security continues to be breached.

Physical attacks can consist of timing attacks, power attacks, and acoustic attacks, while tampering attacks include fault and radiation attacks.
