Group key agreement (GKA) allows a set of players to establish a shared secret and thus bootstrap secure group communication. GKA is very useful in many types of peer group scenar...
Many implementations of cryptographic algorithms have shown to be susceptible to fault attacks. For some of them, countermeasures against specific fault models have been proposed. ...
Constructing sensing barriers using wireless sensor networks has important applications in military operations and homeland security. The goal of forming a sensing barrier is to de...
