Message forwarding is a fundamental brick to spread information among users in opportunistic networks. In this paper, the authors consider the recently proposed interest-casting networking primitive for opportunistic networks, according to which a packet generated by a sender should be delivered to all users in the network - potentially unknown to the sender - sharing similar interests. However, the current implementation of interest-casting assume users exchange their interest profiles to take forwarding decisions, thus revealing very sensitive information to strangers.
