General requirements and security architecture for mobile phone anti-cloning measures

The impressive number of counterfeit and stolen mobile phones as well as the emergence of applications where the authentication of mobile terminal is needed shows the critical importance of reliable protection of the mobile device identity. Counterfeiters may use for their products identifiers allocated for genuine handsets. Besides, forgery of the International Mobile Equipment Identity (IMEI) is not too difficult for most of existing smartphones as their software which is the last source of IMEI before sending it to network is vulnerable to modifications. In this paper we argue that there is a need for developing of anti-cloning tool for the mobile devices, which efficacy should not depend on manufacturers. The basic requirements for the novel security architecture were formulated. We introduced “provable experience” authentication factor of mobile device which is dual with respect to the “social network” authentication factor of user. A novel method of multi-factor authentication of mobile device is proposed based on this, which allows effective blocking of clones in cellular networks and does not require standardization or changes in mobile device construction.
