We introduce a robust and efficient mix-network for exponentiation, and use it to obtain a threshold decryption mix-network for ElGamal encrypted messages, in which mix servers do not need to trust each other for the correctness of the result. If a subset of mix servers cheat, they will be caught with an overwhelming probability, and the decryption can restart after replacing them, in a fashion...

We propose a variant mix-net method, which we call a “marked mix-net” . Marked mix-nets avoid the extra cost associated with verifiability (producing a proof of correct mixing operation), while offering additional assurances about the privacy of the messages, compared to a non-verifiable mix-net. With a marked mix-net, each mix-server adds an extra secret mark in each ciphertext, and the input ...

applying robust optimization to solve product mix problem in automotive industries in this article, applying robust optimization in product mix problem in automotive industries is presented. the problem includes determining both the quantity and the identification of each product to produce to maximize profit. at first, the deterministic model will be presented. then, robust model of product mi...

we use many kinds of combinations of raw materials and production levels in producing composite materials. testing all the states are difficult or even impossible. taguchi method is a numerical method which predicts optimum state of composite materials using special orthogonal arrays. in this research we have discussed useablity of this method and its’ potential in finding optimum mix design of...

introduction: increasing pressure on available funds in health care section especially hospitals, enhances the need of analyzing different strategies in economic terms. one of the solutions for the optimal use of financial resources and potentials in hospitals and health care centers is using elements of the marketing mix. in this way we could make the best use of the resources and cause a retu...

The contribution of this paper is twofold. First we present a new simple electronic voting scheme having standard re-encryption mix net back-end, which allows to cast a ballot and verify its correctness in a new way. Then we extend the proposed scheme to represent a new very efficient mix network construction. We called our mix network to be self-proving mix, because it is shown how mix process...
