We describe an efficient hash-based signature scheme that yields shorter signatures than
the state of the art. Signing and verification are faster as well, and the overall scheme is …

Unattended wireless sensor networks (UWSNs) are operated in hostile environments
without constant supervision by a trusted sink; so it faces the risk of compromising by …

In this study, we propose an efficient aggregate signcryption scheme to maximize the
security of data in a kind of wireless medical network named the disconnected or unattended …

In a mobile Unattended Wireless Sensor Network (UWSN), a trusted sink visits each sensor
node periodically to collect data. Data has to be secured until the next visit of the sink …

An Unattended Wireless Sensor Network (UWSN) is a type of sensor network where a
trusted sink visits each node periodically to collect the data. Due to the offline nature of this …

Mobile sink-based sensor networks deployed in unattended environment are characterized
by infrequent sink visits. In these applications, ensuring the survivability and confidentiality of …

In Wireless Sensor Networks, the base station is generally the only unconditionally trusted
entity. If it is not connected for a period of time, the network is left unattended and sensor …

In Unattended Wireless Sensor Networks (UWSNs) the nodes are subjected to hostile
environment for sensing critical data. Due to the unattended nature of the network the sink is …

Following a detailed overview of cooperative communications and the physical layer
security, this book proposes relay and jammer selection schemes for security in one-way …

An Unattended Wireless Sensor Network (UWSN) is a type of sensor network where a
