Encryption is less secure than we thought
August 13, 2013For 65 years, most information-theoretic analyses of cryptographic systems have made a mathematical assumption that turns out to be wrong.
Securing the cloud
June 9, 2013A new algorithm solves a major problem with homomorphic encryption, which would let Web servers process data without decrypting it.
Making quantum encryption practical
May 20, 2013An 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
February 15, 2013MIT 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
July 30, 2012Interactive proofs — mathematical games that underlie much modern cryptography — work even if players try to use quantum information to cheat.
