Incremental and decremental secret key agreement [PDF]

2016 IEEE International Symposium on Information Theory (ISIT), 2016
We study the rate of change of the multivariate mutual information among a set of random variables when some common randomness is added to or removed from a subset. This is formulated more precisely as two new multiterminal secret key agreement problems which ask how one can increase the secrecy capacity efficiently by adding common randomness to a ...

Secret key generation through a relay [PDF]

2016 IEEE Information Theory Workshop (ITW), 2016
We consider problems of two-user secret key generation through an intermediate relay. Each user observes correlated source sequences and communicates to the relay over rate-limited noiseless links. The relay processes and broadcasts information to the two users over another rate-limited link.

Efficient Secret Key Delivery Using Heartbeats

MATEC Web of Conferences, 2017
Recently many researchers have employed physiological signals like heartbeats as a source of the key seed used in key establishment protocols. The physiological signals make it easy to establish a secret key between implantable (or attachable) medical ...

Secret key generation from mobility [PDF]

2011 IEEE GLOBECOM Workshops (GC Wkshps), 2011
We consider secret key generation from relative localization information of a pair of nodes in a mobile wireless network in the presence of a mobile eavesdropper. Our scheme consists of two phases: in the first phase, legitimate node pair exchanges beacon signals to establish localization information based on noisy observations of these beacons; in the

Secret Key Agreement for SISO Visible Light Communication Systems

Photonics
This paper studies the use of secret key agreement for single-input single-output (SISO) visible light communication (VLC) systems. Specifically, we put forward a scheme for secret key generation and analyze the secret key rate in SISO VLC systems. First,

Mutual dependence for secret key agreement [PDF]

2010 44th Annual Conference on Information Sciences and Systems (CISS), 2010
A mutual dependence expression is established for the secret key agreement problem when all users are active. In certain source networks, the expression can be interpreted as certain notions of connectivity and network information flow. In particular, the secrecy problem can be mapped to a new class of network coding problems with selectable links and ...

No-go theorem for heralded exact one-way key distillation [PDF]

Quantum
The heralded exact one-way distillable secret key is equal to the largest expected rate at which perfect secret key bits can be probabilistically distilled from a bipartite state by means of local operations and one-way classical communication.

Secret Distribution of Keys for Public-Key Systems [PDF]

, 1988
This paper proposes new public-key cryptosystems systems the security of which is based on the tamperfreeness of a device and the existence of secret key cryptosystems instead of the computational complexity of a trapdoor one-way function (RSA).
