Mobile phone call privacy under threat

The gradual improvement in the effectiveness of attacks on the GSM network has progressed ever since the encryption algorithm used became open, and weaknesses were identified. Improvements in processing power have allowed faster key searches, and now new research breaks further aspects of the GSM architecture to crack the encryption using simple hardware. It wont be long before commercial eavesdroppers will be available cheaply. My guess is that new security and encryption will have to be added to GSM, somehow, and soon.
