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.

Multi-dimensional key generation of ICMetrics for cloud computing [PDF]
, 2015 Despite the rapid expansion and uptake of cloud based services, lack of trust in the provenance of such services represents a significant inhibiting factor in the further expansion of such service.

Multiuser secret key generation based on received signal
网络与信息安全学报, 2018 The secret key generation method based on channel characteristic provides a new way for communication security.But under the conditions of multiuser and slow fading,because of the slow channel parameter changing rate,using the secret key generation ...

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 ...

Centralized Threshold Key Generation Protocol Based on Shamir Secret Sharing and HMAC Authentication
Sensors, 2022 Many group key management protocols have been proposed to manage key generation and distribution of vehicular communication. However, most of them suffer from high communication and computation costs due to the complex elliptic curve and bilinear pairing

Tamper-proof secret image-sharing scheme for identifying cheated secret keys and shared images [PDF]
, 2013 A (t,n) secret image-sharing scheme shares a secret image to n participants, and the t users recover the image. During the recovery procedure of a conventional secret image-sharing scheme, cheaters may use counterfeit secret keys or modified shared ...

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

Asynchronous quantum key distribution on a relay network [PDF]
, 2012 We show how quantum key distribution on a multi-user, multi-path, network can be used to establish a key between any two end-users in an asynchronous fashion using the technique of bit-transport.

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 ...
