Abstract EN
Information-theoretic secrecy is combined with cryptographic secrecy to create a secret-key exchange protocol for wirelessnetworks.
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, homogeneous Poisson process and independent uniformly distributed points, are used for the spatial distributions of transmitters and eavesdroppers.
We analyse the impact of the number of cooperating transmittersand the number of eavesdroppers on the area fraction where secure communication is possible.
Upper bounds on the probability of existence of positive secrecy between the cooperating transmitters and the receiver are derived.
The closeness of the upper bounds to the real value is then estimated by means of numerical simulations.
Simulations also indicate that a deterministic spatial distribution for the transmitters, for example, hexagonal and square lattices, increases the probability of existence of positive secrecy capacity compared to the random spatial distributions.
For the same number of friendly nodes, cooperative transmitting provides a dramatically larger secrecy region than cooperative jamming and cooperative relaying.
