A5/1 yakatanga kugadzirwa uye yakasimba algorithm inoshandiswa mukati meEurope neUnited States; A5/2 haina kusimba uye inoshandiswa mune dzimwe nyika. Kukanganisa kwakakomba kwakawanikwa mune zvose zviri zviviri algorithms: zvinokwanisika kuputsa A5/2 munguva chaiyo ne ciphertext-only attack, uye muna Ndira 2007, The Hacker's Choice yakatanga chirongwa cheA5/1 chekupwanya nehurongwa hwekushandisa FPGAs inobvumira A5/1 kuputsika ne rainbow table attack. Sisitimu inotsigira akawanda algorithms saka vanoshanda vanogona kutsiva iyo cipher neimwe yakasimba. Mubvunzo: Ndeipi yakanyanya kusimba pane maviri?
