On secret key generation through multipath for wireless networks

IEEE International Symposium on Signal Processing and Information Technology, 2013
The complexity of cryptographic key management and the wireless medium salient features motivated a number of works that generate secret keys. Simply put, two nodes can estimate their wireless channel and derive common information to generate a key that other nodes cannot obtain.

Optimal Pilots for Maximal Capacity of Secret Key Generation

2019 IEEE Global Communications Conference (GLOBECOM), 2019
Through a wireless channel, two users can transmit pilot signals to each other, and then utilize the received signals to agree upon a secret key through communications in a public channel without leaking any secret about this key to anyone else. This paper addresses the optimization of the two pilots to maximize the capacity of secret key generation ...

Secret-key generation with correlated sources and noisy channels

2008 IEEE International Symposium on Information Theory, 2008
A joint-source-channel setup for secret-key generation between remote terminals is considered. The sender communicates to the receiver over a discrete memoryless wiretap channel and the sender and receiver observe a pair of correlated discrete memoryless sources. Lower and upper bounds for the secret-key rate are presented and shown to coincide for the

Dynamic Key Generations for Secret Sharing in Access Structures

19th International Conference on Advanced Information Networking and Applications (AINA'05) Volume 1 (AINA papers), 2005
In a secret sharing scheme based upon access structures, each group has an authorization and only the participants who stayed in an authorized access structure can recover the secret key. In this paper, we proposed an efficient scheme for secret sharing based upon access structures.

On secret key generation from finite source observations

2014 48th Annual Conference on Information Sciences and Systems (CISS), 2014
All existing secret key generation schemes assume that the users have access to infinite number of source observations. Motivated by applications in wireless networks, we consider the problem of generating secret keys from a finite number of correlated observations under the source model.
