團簽(group signature)指的是一個團體裡面任何一個團員皆可以匿名地代表該團體對外簽署文件。當簽章有爭議時,該團體的管理員可追蹤簽章者。為了取信於大眾,管理員可提供額外的信息,讓每一個人可追蹤該簽章者,但公佈此額外信息是否會使該簽章者其他匿名簽署的文件也跟著曝光,這種稱為連結問題(linkage problem),在以前團簽的論文較少討論。本論文提供一個新的植基於身份團簽方法,當簽章有爭議時,任何人可利用管理員公佈的額外信息去追蹤簽章者而且也不會發生所謂的連結問題。
A group signature scheme allows a group member to sign a document anonymously on behalf of the official group. In case of disputes, the group manager can trace the signer. In order to win the confidence of the masses, the group manager can offer extra information to everyone in order to trace the signer. But in doing so, the group manager who published the extra information discloses the signer from other document that was signed anonymously, which is called the "linkage problem". Currently relevant schemes are seldom discussed. In this paper, we propose a new ID-based group signature scheme. In case of a dispute, everyone can trace the signer by the extra information which the group manager published and can solve the linkage problem.
