D3.3: Study on Mobile Identity Management

Study on Mobile Identity Management CONCLUSIONS

In spite of the fact that further analysis is still needed to reach a definitive conclusion on the comparison of anonymity mechanisms for ad hoc networks, it seems that none of these mechanisms is fully compliant with ad hoc network requirements. Therefore, the initial conclusion is that anonymity in ad hoc networks cannot be fully achieved with the current proposals and mechanisms for P2P anonymous communication protocols. Therefore, a new anonymous communication mechanism compliant with the requirements of ad hoc network environments needs to be designed.

However, the evaluation of future possible mechanisms shall not only consider the aspects regarding the conformance with ad hoc networks, but, of course, shall also include an evaluation of the anonymity provided regarding different qualitative and quantitative properties, such as the level of anonymity, the fairness (distribution of the protocol burden among devices), the confidentiality provided, etc. Moreover, different and complementary methods can be used for evaluating some of these parameters. For instance, the level of anonymity evaluation can be obtained using the levels proposed in Hordes in conjunction with the Freiburg Privacy Diamond proposal that is based in the attackers’ knowledge and has location privacy concerns.
