Доверитель разделяет доверенность между участниками P, таким образом, что только t (t &lt; n) участников и Арбитр, объединившись, могут вычислить подпись. Таким образом, для подписания документа требуется согласие не менее чем t участников. Арбитр участвует в алгоритме в качестве третьего доверенного лица. Он завершает вычисление подписи на основании информации, полученной от t участников. Проверяющий может идентифицировать участников множества P и доверителя. Главной особенностью алгоритма является то, что n участников, вычисляя подпись, не могут вычислить значения секретного ключа доверителя и доверенности.</p></abstract><trans-abstract xml:lang="en"><p>The paper presents an (n, t)-threshold proxy signature scheme with an Arbitrator which enables an original signer to delegate the signature authority to sign a message on behalf of the original signer to proxy group P of n members. The original signer distributes the proxy key among the proxy group members in such a way that not less then t proxy signers and the Arbitrator can cooperatively sign messages on behalf of the original signer. Thus, for signing the document it is necessary to have agreements of not less then t members. The Arbitrator is a trusted third party. It receives the information from the t members and completes the calculation of the digital signature. A verifier can identify the original signer and the members of the proxy group P. The main feature is that n members of the proxy group can not calculate the proxy key and the original signer’s secret key.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>доверенные цифровые подписи</kwd><kwd>пороговые доверенные цифровые подписи</kwd><kwd>разделение секрета</kwd></kwd-group><kwd-group xml:lang="en"><kwd>proxy signature</kwd><kwd>threshold proxy signature</kwd><kwd>secret sharing</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Mambo M., Usuda K., and Okamoto E.
