Security Experts Poke Theoretical Holes in 3g Encryption
Credit: Telecoms.com
Weizmann Institute of Science researchers recently created a theoretical attack capable of breaking the encryption protocol that is planned for use on 3G telephony. The researchers say the planned encryption protocol for 3G networks is as weak the 20-year-old encryption cipher currently being used to protect 2G networks, which German security researcher Karsten Nohl recently claimed he could crack with a single high-end PC. The 2G encryption algorithm will be replaced by a new cipher called Kasumi, which is a modified version of the Misty cryptosystem.
Weizmann's Orr Dunkleman, Nathan Keller, and Adi Shamir claim that modifications made to create Kasumi actually make the cryptosystem substantially weaker. Once fully adopted, Kasumi will be one of the most widely used cryptosystems in the world.
