Recently, Identity-Based Cryptography (IBC) schemes have been considered as a tool to secure Mobile Ad Hoc Networks (MANETs) due to the efficient key management of the schemes. In this work, we focus on the role of the Key Generation Centre (KGC) as a key escrow, a property that is inherent to all IBC schemes. We explore the special role of key escrow in MANETs and show that this role significantly differs from key escrows in other networks. We introduce two adversary models for dishonest KGCs in MANETs, including a new spy model where a KGC uses so-called spy nodes that record communications in the network and report them to the KGC. We discuss the two faces of key escrow in MANETs, where our analytical results show that in many MANET applications the KGC can be prevented from being a key escrow. On the other hand, the results of this paper illustrate how a KGC can utilise spy nodes to monitor nodes in a MANET, as needed in some applications.
