The use of converge-cast traffic and in-network processing to
minimize the amount of transmitted data is a frequently used
approach to increase the lifetime of a wireless sensor network
(WSN). Consequently, when aiming at security for WSNs, one has
to focus primarily on protecting this type of traffic. Some
recent proposals support the encryption of converge-cast traffic
with in-network processing. However, they either require the
transmission of the sensors’ IDs, creating additional data overhead
linear in the number of sensors, or require an elaborate key
pre-distribution mechanism. In this paper we propose a solution for
end-to-end encryption of converge-cast traffic with a simple key
pre-distribution scheme causing additional data only logarithmic in
the number of sensors. The scheme is robust with respect to
unreliable channels, exhausted nodes, and routing flexibility.
It supports refreshing the keys at the nodes, which has so far
been fully neglected.

User privacy is a growing requirement in the evolution of
communication networks. In this sense, the concept of
virtual personae, which corresponds at different
identities of the same user, starts getting much attention.
However, to provide privacy and non-linkage between these
virtual users, a cross-layer approach to identity needs to
be supported.
This paper proposes a solution to preserve the application
layer privacy models by applying the virtual personae concept
throughout the network stack. It also proposes mechanisms
for non-correlation between identities in 4G mobile
environments, and addresses the benefits of the evolving
multi-homing characteristics of 4G networks to enrich the
non-linkage between identities support of our privacy solution.

abstract = {
This paper details a novel architecture, MobiSplit
[17], for managing mobility in future IP based networks. The
architecture separates mobility management in two levels, local
and global, that are managed in completely independent ways.
We describe how such a mobility architecture can be used to
support a new paradigm in mobility. By combining the user's
identity with a multi physical virtual terminal we treat the
movement of people rather than their physical manifestations
in one device. We conclude by analyzing the concrete system,
built from this new architecture and existing protocols, in
terms of scalability, flexibility and security.

Wireless LAN and other radio broadcast technologies are now in full swing.
However, the widespread usage of these technologies comes at the price of
location privacy, be it by observing the communication patterns or the
interface identifiers. Although a number of network level solutions have
been proposed , this paper describes a novel approach to location privacy
at the link layer level. We present a generic mechanism and then map it to
a real protocol, IEEE 802.11. The work also provides an analysis of the
protocol in terms of privacy and performance considerations.

Aggregator nodes commonly have the ability to read,
corrupt or disrupt the flow of information produced by a Wireless
Sensor Network (WSN). Despite this fact, existing aggregator
node election schemes do not address an adversary that strives
to influence the election process towards candidate nodes that it
controls. We discuss the requirements that need to be fulfilled
by a non-manipulable aggregator node election protocol. We
conclude that these requirements can be satisfied by a distributed
random number generator function in which no node is able to
determine the output of the function. We provide and compare
three protocols that instantiate such function.
