In this work, we present a novel consensus-based secondary control scheme for current sharing and voltage balancing in dc microgrids (DCmGs), composed of distributed generation units (DGUs), dynamic RLC lines, nonlinear ZIE (constant impedance, constant current, exponential) loads. Situated atop primary layer, our controllers have structure utilize information exchanged over communication netwo...

Recently, verifiable secret sharing schemes have been proposed to keep participants from providing fake or illegal stego-images. However, the schemes do not consider the recovery mechanism when parts of the information in stego-images are lost or incidentally modified during the transmission process. This paper presents a novel verifiable and reversible secret sharing scheme based on Shamir’s s...

time sharing contracts are a new type of contracts relating to immovable property created in response to modern life necessities. the main feature of this type of contract is that the ownership of property is transferred to the buyer for a limited period of the year. unlike traditional sale contracts in which the buyer acquires the complete and continuous ownership of the property purchased, in...

In his paper [9], Stadler develops techniques for improving the security of existing secret sharing protocols by allowing to check whether the secret shares given out by the dealer are valid. In particular, the secret sharing is executed over abelian groups. In this paper we develop similar methods over non-abelian groups.
