Making quantum encryption practical
An MIT team that proposed a new, more-practical scheme for using quantum physics to secure data transmission has now demonstrated it experimentally.
Beefing up public-key encryption
MIT researchers show how to secure widely used encryption schemes against attackers who have intercepted examples of successful decryption.
10-year-old problem in theoretical computer science falls
Interactive proofs — mathematical games that underlie much modern cryptography — work even if players try to use quantum information to cheat.
Four innovative technologies garner 2012 R&D 100 Awards for MIT Lincoln Laboratory
Awards recognize a diverse range of technologies
Thwarting the cleverest attackers
Savvy 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 incentives
A new twist on pioneering work done by MIT cryptographers almost 30 years ago could lead to better ways of structuring contracts.
Quantum computing with light
A switch that lets one photon alter the quantum state of another could point the way to both practical quantum computers and a quantum Internet.
Hippie days
How a handful of countercultural scientists changed the course of physics in the 1970s and helped open up the frontier of quantum information.
Protecting medical implants from attack
A new system would jam wireless signals sent to medical implants by unauthorized users.
Rivest unlocks cryptography's past, looks toward future
Public-key system has worked and made Internet commerce feasible, but new systems are ready in case flaws are found.
Cryptographic voting debuts
A 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 secure
Even well-defended computers can leak shocking amounts of private data. MIT researchers seek out exotic attacks in order to shut them down
