This paper addresses the question of multi-party computation in a model with asymmetric information. Each agent has a private value (secret), but in contrast to standard models, the agent incurs a cost when retrieving the secret. There is a social choice function the agents would like to compute and implement. All agents would like to perform a joint computation, which input is their vector of ...

An efficient, computationally secure, verifiable (t, n) multi secret sharing scheme, based on YCH is proposed for multiple 3D models. The (t, n) scheme shares the 3D secrets among n participants, such that shares less than t cannot reveal the secret. The experimental results provide sufficient protection to 3D models. The feasibility and the security of the proposed system are demonstrated on v...

Leonardo da Vinci, the founder and typical representative of Upper Renaissance style, tried his hand at many forms art, advancing advanced ideas in mathematics, mechanics, physics. Each works is based on study life, warmed by heart artist expresses attitude to life. Her masterpiece, Monna Lisa, still haunts all art lovers. It unknown this time what he will do after leaving post.
