Secret key agreement using a virtual wiretap channel
IEEE INFOCOM 2017 - IEEE Conference on Computer Communications, 2017Key agreement using physical layer properties of communication channels is a well studied problem. iJam is a physical layer key agreement protocol that achieves security by creating a “virtual” wiretap channel for the adversary through a subprotocol between the sender and the receiver that uses self-jamming by the receiver. The protocol was implemented

Secret handshakes from pairing-based key agreements
Proceedings 19th International Conference on Data Engineering (Cat. No.03CH37405), 2004Consider a CIA agent who wants to authenticate herself to a server but does not want to reveal her CIA credentials unless the server is a genuine CIA outlet. Consider also that the CIA server does not want to reveal its CIA credentials to anyone but CIA agents - not even to other CIA servers.

Comments on a Secret-Key-Privacy-Preserving Authentication and Key Agreement Scheme
2011 Fifth International Conference on Genetic and Evolutionary Computing, 2011Lots applications need involved parties to share common session keys for specific requirements. For example, the shared key can be the seed to determine locations to hide secret data into an image. Wang et al. proposed an authentication scheme with key agreement based on the elliptic curve discrete logarithm problem in 2011.

Supervising secret-key agreements in a level-based hierarchy
18th International Conference on Advanced Information Networking and Applications, 2004. AINA 2004., 2004A key agreement protocol is utilized in a network system such that two users are able to establish a commonly shared secret key. Entities within the same security level can communicate securely with each other by using the session key. In this paper, we will propose an approach to solve the problem of supervising secure communication in a level-based ...

Secret Key Agreement: Fundamental Limits and Practical Challenges
IEEE Wireless Communications, 2017Despite the tremendous progress made toward establishing PLS as a new paradigm to guarantee security of communication systems at the physical layer, there is a common belief among researchers and industrials that there are many practical challenges that prevent PLS from flourishing at the industrial scale. Most secure message transmission constructions

From secret key agreement to matroidal undirected network
2012 Information Theory and Applications Workshop, 2012An undirected network link model is formulated, generalizing the usual undirected graphical model. The optimal direction for multicasting can be found in polynomial time with respect to the size of the network, despite the exponential number of possible directions.

Robust authentication and key agreement scheme preserving the privacy of secret key
Computer Communications, 2011In ubiquitous computing environments, people may obtain their services from application servers by using mobile devices at any time and anywhere. For convenience, most of those devices are small and of limited power and computation capacity. In this paper, we propose a robust user authentication and key agreement scheme suitable for ubiquitous ...

Secret key agreement for satellite laser communications
2021Free-space optical (FSO) communications offer high-capacity wireless transmission due to their plentiful properties originated from higher carrier frequency. These properties also yield a greater security advantage: the high directionality of the laser beam and the line-of-sight configuration can reasonably restrict an attack model launched by an ...
