概要

• 論文の詳細を見る

• Recently, Kuwakado and Tanaka proposed a transitive signature scheme for directed trees. In this letter, we show that Kuwakado-Tanaka scheme is insecure against a forgery attack, in which an attacker is able to forge edge signatures by composing edge signatures provided by a signer.
