NOVEL DATA HIDING
no vote
There
are also a number of works on data hiding in the encrypted domain. The
reversible data hiding in encrypted image is investigated in. Most of the work
on reversible data hiding focuses on the data embedding/extracting on the plain
spatial domain. A content owner encrypts the original image using an encryption
key, and a data-hider can embed additional data into the encrypted image using
a data-hiding key though he does not know the original content. With an
encrypted image containing additional data, a receiver may first decrypt it
according to the encryption key, and then extract the embedded data and recover
the original image according to the data-hiding key. In a novel scheme for separable reversible data hiding in encrypted image.
In the proposed scheme, the original image is encrypted using an encryption key
and the additional data are embedded into the encrypted image using a
data-hiding key.If

routing misbehavior in MANETs
no vote
We study routing misbehavior in MANETs
(Mobile Ad Hoc Networks) in this paper. In general, routing protocols for
MANETs are designed based on the assumption that all participating nodes are
fully cooperative. However, due to the open structure and scarcely available
battery-based energy, node misbehaviors may exist. One such routing misbehavior
is that some selfish nodes will participate in the route discovery and
maintenance processes but refuse to forward data packets. In this paper, we
propose the 2ACK scheme that serves as an add-on technique for routing schemes
to detect routing misbehavior and to mitigate their adverse effect. The main
idea of the 2ACK scheme is to send two-hop acknowledgment packets in the
opposite direction of the routing path. In order to reduce additional routing
overhead, only a fraction of the received data packets are acknowledged in the
2ACK scheme. Analytical and simulation results are prese
