Thwarting the cleverest attackersSavvy hackers can steal a computer’s secrets by timing its data storage transactions or measuring its power use. New research shows how to stop them.

Algorithmic incentivesA new twist on pioneering work done by MIT cryptographers almost 30 years ago could lead to better ways of structuring contracts.

Quantum computing with lightA switch that lets one photon alter the quantum state of another could point the way to both practical quantum computers and a quantum Internet.

Rivest unlocks cryptography's past, looks toward futurePublic-key system has worked and made Internet commerce feasible, but new systems are ready in case flaws are found.

Cryptographic voting debutsA new system for ensuring accurate election tallies, which MIT researchers helped to develop, passed its first real-world test last Tuesday.

Secure computers aren’t so secureEven well-defended computers can leak shocking amounts of private data. MIT researchers seek out exotic attacks in order to shut them down
