統合シャッフル正当性証明装置、証明統合装置、統合シャッフル正当性検証装置及びミックスネットシステム
Document Type and Number:
Japanese Patent JP4771053
Kind Code:
B2
Abstract:
An integrated shuffle validity proving device (300) is provided correspondingly to an ordinal number » which is an integer representing an order. The device (300) has a permutation proof commitment unit (310) which, on receiving a commitment public key and a permutation storage commitment containing a permutation proof text made by first to (º -1)-th integrated shuffle validity proving devices from outside, encrypts a permutation proof commitment created by adding a permutation proof text made by the K -th integrated shuffle validity proving device to the received permutation storage commitment with the commitment public key and sends the encrypted permutation proof commitment to the outside.
