Chaos Communication Congress conference in Berlin was house to claim by an encryption expert that current standards of security for GSM connections are inadequate and can be compromised, allowing any 3rd party to hack into and listed to your phone calls.
German hacker Karsten Nohl revealed that he has cracked the 64-bit A5/1 encryption which happens to be 21 years old and still in use by most GSM connections around the world. The GSM association has termed Nohl’s research as illegal as per laws and claimed that hacking telecom lines is much more complicated than it is being portrayed. In this case though things aren’t as simple as hacking a website over the internet, I see no reason why hackers cant make an attempt to get the required radio receiver system and signal processing software to process raw radio data for this purpose.
While the GSM Association is in denial, security experts believe that most operators have avoided the investment in upgrading to the newer 128-bit A5/1 encryption algorithm that is (atleast till now) considered secure enough. However 3G networks are believed to work on the new standard, another reason to speed up the switch from 2G to 3G?
