Improvements in Brute Force Attacks

New paper: "GPU Assisted Brute Force Cryptanalysis of GPRS, GSM, RFID, and TETRA: Brute Force Cryptanalysis of KASUMI, SPECK, and TEA3." Abstract: Key lengths in symmetric cryptography are determined with respect to the brute force attacks with current technology. While nowadays at least 128-bit...

Researchers Show Method to Decrypt GPRS Traffic

A security researcher known for his work on cracking cryptographic ciphers on mobile networks has found a method that enables him to capture and decrypt data traffic on virtually any GPRS network. The attack, developed by Karsten Nohl, enables him to eavesdrop on traffic within a radius of about...

A Second GSM Cipher Falls

A group of cryptographers has developed a new attack that has broken Kasumi, the encryption algorithm used to secure traffic on 3G GSM wireless networks. The technique enables them to recover a full key by using a tactic known as a related-key attack, but experts say it is not the end of the worl...
