A designated verifier signature is a signature scheme in which signatures can only be verified by a single designated verifier who is chosen by the signer. Designated verifier signatures were first proposed in 1996 by Jakobsson Sako, Kazue Sako, and Russell Impagliazzo. Proposed as a way to combine authentication and off-the-record messages, designated verifier signatures allow authenticated, private conversations to take place. Unlike in undeniable signature scheme the protocol of verifying is non-interactive, i.e. the signer chooses the designated verifier (or the set of designated verifiers) in advance and does not take part in the verification process. ==See also== * Non-repudiation * Undeniable signature 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Designated verifier signature」の詳細全文を読む スポンサード リンク
