PVSS stands for publicly verifiable secret sharing. In PVSS, a dealer shares a secret among multiple share holders. He encrypts the shares using the shareholders' encryption algorithms and publicly proves that the encrypted shares are valid. Most of the existing PVSS schemes do not employ an ElGamal encryption to encrypt the shares. Instead, they usually employ other encryption algorithms like ...

A non-interactive, simple and efficient publicly verifiable secret sharing (PVSS) is constructed based on the bilinear pairing on elliptic curves, which has all advantages of Schoenmakers’ PVSS in [15]. Moreover, in the scheme’s distribution of shares phase, only using bilinearity of bilinear paring, anybody can verify that the participants received whether correct shares without implementing i...

We present a new protocol to perform non-interactive verifiable secret redistribution (VSR) for secrets distributed with Shamir’s secret sharing scheme. We base our VSR protocol on Desmedt and Jajodia’s redistribution protocol for linear secret sharing schemes, which we specialize for Shamir’s scheme. We extend their redistribution protocol with Feldman’s non-interactive verifiable secret shari...

Publicly verifiable secret sharing (PVSS) allows not only shareholders themselves but also everyone verify the shares of a secret distributed by a dealer. It has a lot of electronic applications. In this paper, we propose a publicly verifiable member-join protocol for threshold signatures. In our proposal, a new member can join a PVSS scheme to share the secret only with the help of old shareho...

Uniform randomness beacons whose output can be publicly attested to be unbiased are required in several cryptographic protocols. A common approach to building such beacons is having a number parties run a coin tossing protocol with guaranteed output delivery (so that adversaries cannot simply keep honest parties from obtaining randomness, consequently halting protocols that rely on it). However...

Leadership is important for nurturing employee creativity. Although how leaders can influence employee creativity is somehow unclear, previous studies show that leadership can enhance employees’ willingness to share knowledge. This study examines how leader-member exchange (LMX) affects employees’ creative work involvement through knowledge sharing. Data (n=385) was collected utilizing a questi...

introduction: organizational citizenship behavior has been linked to overall organizational effectiveness, thus these types of employee behaviors have important consequences in the workplace. one of the important consequences of these types of behaviors is knowledge sharing. thus, the current study examined the role of organizational citizenship behavior in promoting knowledge sharing. method: ...

microgrids are nowadays used to produce electric energy with more efficiency and advantage. however, the use of microgrids presents some challenges. one of the main problems of the microgrids widely used in electrical power systems is the control of voltage, frequency and load sharing balance among inverter- based distributed generators (dgs) in islanded mode. droop method performance degrades ...
