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 ...

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 ...

Converses For Secret Key Agreement and Secure Computing [PDF]
IEEE Transactions on Information Theory, 2015 We consider information theoretic secret key agreement and secure function computation by multiple parties observing correlated data, with access to an interactive public communication channel. Our main result is an upper bound on the secret key length, which is derived using a reduction of binary hypothesis testing to multiparty secret key agreement ...

Experimental demonstration of multiparty quantum secret sharing and conference key agreement
npj Quantum Information, 2023 Quantum secret sharing (QSS) and conference key agreement (CKA) provide efficient encryption approaches for realizing multi-party secure communication, which are essential components of quantum networks. In this work, a practical, scalable, verifiable (k,

On the Optimality of Secret Key Agreement via Omniscience [PDF]
IEEE Transactions on Information Theory, 2018 For the multiterminal secret key agreement problem under a private source model, it is known that the maximum key rate, i.e., the secrecy capacity, can be achieved through communication for omniscience, but the omniscience strategy can be strictly suboptimal in terms of minimizing the public discussion rate.

The Secret Key Capacity of a Class of Noisy Channels with Correlated Sources
Entropy, 2019 This paper investigates the problem of secret key generation over a wiretap channel when the terminals observe correlated sources. These sources are independent of the main channel and the users overhear them before the transmission takes place.

Secret Sharing-based Authenticated Key Agreement Protocol [PDF]
Proceedings of the 16th International Conference on Availability, Reliability and Security, 2021 In this article, we present two novel authenticated key agreement (AKA) schemes that are easily implementable and efficient even on constrained devices. Both schemes are constructed over elliptic curves and extend Schonorr’s signature of knowledge protocol.

Secret-Key Agreement without Public-Key Cryptography [PDF]
, 2007 In this paper, we describe novel approaches to secret-key agreement. Our schemes are not based on public-key cryptography nor number theory. They are extremely efficient implemented in software or make use of very simple uuexpensive hardware. Our technology is particularly well-suited for use in cryptographic scenarios like those of the Clipper Chip ...
