概要

• 論文の詳細を見る

• This paper describes an efficient k-out-of-n threshold digital signature scheme for a smart card based system where a signer used multiple cards so that the signature can be issued in a dependable manner. The main feature of our method is that it dose not require a secret communication path among these cards in the signature issuing protocol, and that it requires low communication and computational complexity. Former is an advantage under the current export control regulation which makes hard to export more than 56-bit cipher techniques, and latter is advantage over so-called robust signature.
