    Mobile ad hoc networks (MANETs) are self-configuring infrastructure-less networks comprised of
    mobile nodes that communicate over wireless links without any central control on a peer-to-peer basis.
    These individual nodes act as routers to forward both their own data and also their neighbours’ data by
    sending and receiving packets to and from other nodes in the network. The relatively easy configuration
    and the quick deployment make ad hoc networks suitable the emergency situations (such as human or
    natural disasters) and for military units in enemy territory. Securing data dissemination between these
    nodes in such networks, however, is a very challenging task. Exposing such information to anyone else
    other than the intended nodes could cause a privacy and confidentiality breach, particularly in military
    scenarios. In this paper we present a novel framework to enhance the privacy and data confidentiality in
    mobile ad hoc networks by attaching the originator policies to the messages as they are sent between
    nodes. We evaluate our framework using the Network Simulator (NS-2) to check whether the privacy and
    confidentiality of the originator are met. For this we implemented the Policy Enforcement Points (PEPs),
    as NS-2 agents that manage and enforce the policies attached to packets at every node in the MANET.
