Multi-Party Secret Key Agreement Over State-Dependent Wireless Broadcast Channels

Abstract

Multi-Party Secret Key Agreement Over State-Dependent Wireless Broadcast Channels project report  We consider a group of m trusted and authenticated nodes that aim to create a shared secret key K over a wireless channel in the presence of an eavesdropper Eve. We assume that there exists a state dependent wireless broadcast channel from one of the honest nodes to the rest of them including Eve.

All of the trusted nodes can also discuss over a cost-free, noiseless and unlimited rate public channel which is also overheard by Eve. For this setup, we develop an information-theoretically secure secret key agreement protocol. We show the optimality of this protocol for “linear deterministic” wireless broadcast channels. This model generalizes the packet erasure model studied in literature for wireless broadcast channels.

Conclusion

Multi-Party Secret Key Agreement Over State-Dependent Wireless Broadcast Channels project report on web mining Here, in this section we bring forward discussion about multi-party secret key sharing problem, open questions and possible future directions. Multi-Party Secret Key Agreement Over State-Dependent Wireless project report on web mining First, the SKG capacity problem among multiple terminals over a state-dependent Gaussian channel in the presence of a passive eavesdropper is still unsolved. But, the optimality of the proposed multi-party secret key sharing scheme has been shown for deterministic channels (that includes the erasure channels as a special case).
