Securely Computing the Three-Input Majority Function with Eight Cards

Comparison of Three Soft Computing Methods in Estimating Apparent Shear Stress in Compound Channels

Apparent shear stress acting on a vertical interface between the main channel and floodplain in a compound channel serves to quantify the momentum transfer between sub sections of this cross section. In this study, three soft computing methods are used to simulate apparent shear stress in prismatic compound channels. The Genetic Algorithm Artificial neural network (GAA), Genetic Programming (GP...

Computations with a deck of cards

A deck of cards can be used as a cryptographic tool ([3], [6]). Using a protocol that securely computes the Boolean AND function, one can construct a protocol for securely computing any Boolean function. This, in turn, can be used for secure multiparty computations, solitary games, zero knowledge proofs and other cryptographic schemes. We present a protocol for people to securely compute the AN...

Card-Based Protocols for Any Boolean Function

Card-based protocols that are based on a deck of physical cards achieve secure multi-party computation with information-theoretic secrecy. Using existing AND, XOR, NOT, and copy protocols, one can naively construct a secure computation protocol for any given (multivariable) Boolean function as long as there are plenty of additional cards. However, an explicit sufficient number of cards for comp...

The Five-Card Trick Can Be Done with Four Cards

The “five-card trick” invented by Boer allows Alice and Bob to securely compute the AND function of their secret inputs using five cards—three black cards and two red cards—with identical backs. This paper shows that such a secure computation can be done with only four cards. Specifically, we give a protocol to achieve a secure computation of AND using only four cards—two black and two red. Our...
