Code That Protects Most Mobile Phone Calls Is Divulged

Posted in: Noms de Domaine at 30/12/2009 17:13

A German computer engineer said Monday that he had deciphered and published the secret code used to encrypt most of the world's digital mobile phone calls, in what he called an attempt to expose weaknesses in the security of global wireless systems.

The action by the encryption expert, Karsten Nohl, aimed to question the effectiveness of the 21-year-old GSM algorithm, a code developed in 1988 and still used to protect the privacy of 80 percent of mobile calls worldwide.

Secret mobile phone code cracked
Computer hackers this week said they had cracked and published the secret code that protects 80 per cent of the world's mobile phones. The move will leave more than 3bn people vulnerable to having their calls intercepted, and could force mobile phone operators into a costly upgrade of their networks.

Karsten Nohl, a German encryption expert, said he had organised the hack to demonstrate the weaknesses of the security measures protecting the global system for mobile communication (GSM) and to push mobile operators to improve their systems.
