| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Consider a scenario where there are $n$ players who want to exchange gifts. That is, we want to generate a random permutation having no fixed point. It is known that such a random permutation can be obtained in a hidden way by using a number of cards of four colors with identical backs, such that it has no fixed point for sure without revealing the permutation itself. This paper deals with such a problem and improves the known result: while the known protocol needs $O(n^2)$ cards of four colors, our improved protocol requires only $O(n log n)$ cards of two colors. |
