Security is one of the main challenges in Ad Hoc Mobile Networks (MANETs - Mobile Ad Hoc Networks). The natural characteristics of MANETs make these networks highly vulnerable to many attacks, starting from physical layer to the application layer. There are various algorithms and protocols to deal with these threats. All these algorithms have a common element: the use of encryption. Among the cryptographic systems found in the literature, those based on identity seem to be better adapt to the paradigm of MANETs. Its main advantages are the low computational cost and reduced overhead. This work presents an evaluation of the main identity-based cryptographic schematic for the MANETs, Identity Key Management (IKM). The evaluation was performed considering the renewal and revocation of keys and the presence of attacks of false accusation. The results show that the IKM is vulnerable to this attack and the partitioning of the network may lead you to an unstable state.
