In wireless sensor network (WSN), a secure link in the key pre-distribution (KP) scheme may
be compromised when sensor nodes are captured. Accordingly, the KP q-composite …

Recently, Ehdaie et al. proposed a two-dimensional hash chain based key pre-distribution
(2DHC-KPD) scheme that can enhance resiliency against node-capture attack when …

The k-Secure t-Conference key distribution scheme (kStC-KDS) provides dynamic
conferences in wireless sensor networks, which any group of t sensor nodes can derive a …

We refer to an access control system based on subjects and objects. Subjects are active
entities, eg processes, while objects are passive entities, eg messages exchanged between …

We refer to a distributed architecture consisting of sensor nodes connected by wireless links
and organized in a tree-shaped hierarchy. We present a paradigm for the management of …

With reference to a distributed environment consisting of nodes connected in an arbitrary
network topology, we propose the organization of a protection system in which a set of …

We refer to a key-based protection environment featuring active subjects and protected
objects. A subject that possesses a key for a given object is allowed to access this object to …

This work falls within the context of security in wireless sensor networks. The aim of this work
is to realize applications based on security mechanisms already present in the literature …
