Secure multi-party computation can be implemented by
using a (big) PEZ dispenser,
which is called as a ¥textit{private PEZ protocol}.
In the original Balogh et al.'s paper,
a protocol for computing an arbitrary function
was presented by using a huge number of candies.
For instance, 6941 candies are necessary for computing an
¥textit{arbitrary} function with 4 inputs.
However, we can reduce the number of candies
if we design a protocol for calculating a ¥textit{specific} function.
Actually, Yamamoto et al.¥ proposed a private PEZ protocol with 107
candies for computing 4-input majority vote.
This protocol is obtained by carefully analyzing the private PEZ protocol
for 3-input majority vote with 13 candies provided
in the Balogh et al.'s paper without any derivation.
This analysis tells us that the protocol is obtained recursively.
Using this structure, we show in this paper that the number
of candies can further be reduced and
only 29 candies are sufficient for the 4-input majority vote. |
