Secure Wireless Communications via Cooperative Transmitting

Secure Wireless Communications via Cooperative Transmitting

Information-theoretic secrecy is combined with cryptographic secrecy to create a secret-key exchange protocol for wireless networks. A network of transmitters, which already have cryptographically secured channels between them, cooperate to exchange a secret key with a new receiver at a random location, in the presence of passive eavesdroppers at unknown locations. Two spatial point processes, ...

Secure Trust-based Cooperative Communications in Wireless Multi-hop Networks

The word cooperate derives from the Latin words co-and operate (to work), thus it connotes the idea of “working together”. Cooperation is the strategy of a group of entities working together to achieve a common or individual goal. The main idea behind cooperation is that each cooperating entity gains by means of the unified activity. Cooperation can be seen as the action of obtaining some advan...

Secure Communications over Wireless Channels

In this work, we present new techniques that leverage the wireless medium in facilitating secure communications in the presence of eavesdroppers. First, we consider the secure transmission of information over an ergodic fading channel with long coherence intervals. The secrecy capacity of such a system is characterized under different assumptions on the available channel state information. We t...
