Abstract(in English) | This paper proposes new card-based cryptographic protocols using private operations. Randomization is the key operation in card-based cryptographic protocols. If the value used in a randomization is disclosed, the secret value is also disclosed. Thus the randomization must be executed in a secure manner. Executing secure randomization in a completely public space is difficult to realize without some additional cards, thus private operations were considered, in which the operations are executed where the other players cannot see. Some protocols were shown for some special cases when one of the input values is a private value for a player. This paper shows new protocols using private operations which realize logical and, logical or, logical xor, and copy protocols. The number of cards used in these protocols is the minimum. |
