Capacity of a shared secret key [PDF]
2010 IEEE International Symposium on Information Theory, 2010 Shannon theoretic shared secret key generation by multiple terminals is considered for a source model in which the components of a discrete memoryless multiple source and a noiseless public channel of unlimited capacity are available for accomplishing this goal.

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

Reversible Data Hiding in Encrypted Image Using Multiple Data-Hiders Sharing Algorithm
Entropy, 2023 Reversible Data Hiding in Encrypted Image (RDHEI) is a technology for embedding secret information in an encrypted image. It allows the extraction of secret information and lossless decryption and the reconstruction of the original image.

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.

Stego-chain: A framework to mine encoded stego-block in a decentralized network
Journal of King Saud University: Computer and Information Sciences, 2022 Traditional image steganography conceals secret data into the cover image and then transmits the resulting stego-image to the intended recipient via an insecure channel.

ARQ-Based Secret Key Sharing [PDF]
2009 IEEE International Conference on Communications, 2009 This paper develops a novel framework for sharing secret keys using existing Automatic Repeat reQuest (ARQ) protocols. Our approach exploits the multi-path nature of the wireless environment to hide the key from passive eavesdroppers. The proposed framework does not assume the availability of any prior channel state information (CSI) and exploits only ...

Anonymous Quantum Conference Key Agreement
PRX Quantum, 2020 Conference key agreement (CKA) is a cryptographic effort of multiple parties to establish a shared secret key. In future quantum networks, generating secret keys in an anonymous way is of tremendous importance for parties that want to keep their shared ...

Analysis of the conjugacy search problem of the Diffie-Hellman protocol based on the SL(2,3) subgroup [PDF]
ITM Web of ConferencesThe purpose of the Diffie-Hellman key exchange is to establish a shared secret key given that the protocol works in an abelian group setting. In this paper, conditions are presented to attain a shared secret key over a nonabelian group for the well-known
