This work proposes a new trust management system (TMS) for the Internet of Things (IoT).
The wide majority of these systems are today bound to the assessment of trustworthiness …

The internet is a ubiquitous technology that has changed conventional human interactions.
In our present time, it is not unusual for financial transactions to take place virtually with …

Cloud computing security and data protection are becoming increasingly critical as its use
increases. The research we present demonstrates how undercover sharing techniques and …

We introduce CHURP (CHUrn-Robust Proactive secret sharing). CHURP enables secure
secret-sharing in dynamic settings, where the committee of nodes storing a secret changes …

Tompa and Woll introduced a problem of cheating in (k,n) threshold secret sharing schemes.
In this problem k-1 malicious participants aim to cheat an honest one by opening forged …

MPSS is a new way to do proactive secret sharing in asynchronous networks. MPSS
provides mobility: The group of nodes holding the shares of the secret can change at each …

The authors introduce the notion of a 'social secret sharing scheme', in which shares are
allocated based on a player's reputation and the way he/she interacts with other participants …

Abstract A Distributed Key Generation (DKG) protocol is an essential component of
threshold cryptography. DKGs enable a group of parties to generate a secret and public key …

In a threshold scheme, the sensitivity of the secret as well as the number of players may
fluctuate due to various reasons, eg, mutual trust may vary or the structure of the players' …

We first review the notion of social secret sharing and its trust function. We then illustrate
how this construction can be used in cloud computing to create a self-organizing …
