| У нас СОРМ предусматривает по договоренности с сервис-провайдерами. Лучше написать в общем виде: "предоставление сведений об идентификации абонентов-роумеров в их (двух сторон) сетях". |

Traceability - это несокрытие информации. The Global System for Mobile (GSM) [1] is the 1st digital cellular network to provide anonymity to his subscribers. In GSM, non-traceability is provided by using a Temporary Mobile Subscriber Identi ty 1(TMSI). But the main concern with GSM is when a user first switches on his portable phone his International Mobile Subscriber Identi er (IMSI) is transmited in clear through the radio path (the TMSI is allocated only after this step). In the Cellular Digital Packet Data (CDPD) [7], before the authentication procedure takes place, the mobile unit engages a Di e-Hellman key exchange protocol with the visited authority in order to obtain a shared-secret key. Next, the mobile unit's identity is enciphered with this key. The drawback of this approach remains the nature of the Di e-Hellman protocol which allows an intruder to masquerade as the visiting authority and to discover the mobile unit real identity. Even if these approaches are reasonable in their context, the same cannot be guaranteed if perfect privacy is required. In fact what is needed, is a single e cient mechanism allowing a user to access the service of the mobile network while keeping his identity secret as well as the access control mechanism from unauthorized (and authorized) parties. Such mechanisms should take into account di erent degrees of privacy as described in the next section. |
