Na ezt mar nagyon regen akarom beirni.. es akkor vissza is terhetnenk az erdeti temara ill. a nem titkosszolgalati lehallgatasra:


11 Sep 2003

An Israeli scientific team has found a way to break into mobile phone calls on ubiquitous GSM networks, potentially allowing eavesdroppers to listen in on conversations and even take on a caller's identity.

The GSM Association, representing companies which depend on the world's largest mobile system, which is used by more than 860 million consumers in 197 countries, confirmed the security hole but said it would be expensive and complicated to exploit.

Professor Eli Biham of the Technion Institute in Haifa said he was shocked when doctoral student Elad Barkan told him he had found a fundamental error in the GSM (Global System for Mobile communications) code.

"We can listen in to a call while it is still at the ringing stage and within a fraction of a second know everything about the user," Biham said. "Then we can listen in to the call."



Mivel az algoritmust mar 1999-2000 tajekan megtortek (raadasul hozzank kelet Eu-ba a gyengebb jutott...), csak ido kerdese volt hogy mikor finomitjak tovabb; ill. a nagykozonseg alatal is elerheto computing power is szignifikansan nott az utobbi 5 evben. Szoval szerintem nem tulzok ha azt mondom, hogy air-interface-n (levegoben) keresztul torteno lehallgatas mar kb. 3-4 ezer dollar erteku cuccal megoldhato. Persze ott kell lenni a celszemely adokozeleben.
