基于差距Diffie-Hellman群，提出了一种顺序指定的聚合权限转移签名方案.在各种组织中，为了减少拥有相关权限的人所需的批准数量，可以将任务的权限转移给下属或执行该任务的其他人。目前，权力通常是通过一份文件，如权力转移协议来转移的。不过，为了加快程序和保持证据的完整性，我们认为最好通过计算机网络转移这种权力。本文提出了一个基于顺序指定聚合签名和群签名的授权转移签名方案，并提出了一个新的授权转移系统。在签名方法中，使用群签名方案来表示权限。此外，它还将管理者拥有的权力转移给了集团的另一个成员。与群签名的群管理员不同的是，这个管理员不仅管理群，而且还授权。使用订单指定的聚合签名，可以在验证订单的同时有效地处理多个签名。我们表明，一个安全和有效的授权转移系统可以构造使用这种新的数字签名。
We propose an order-specified aggregate authority-transfer signature based on the gap Diffie-Hellman group. In various organizations, to reduce the number of approvals required by someone who has relevant authority, the authority for a task can be transferred to a subordinate or another person who executes the task. Currently, authority is commonly transferred via a document, such as an authority-transfer agreement. However, to speed up the process and maintain the integrity of the evidence, we believe that it is better to transfer such authority via a computer network. In this paper, we propose an authority-transfer signature scheme using an order-specified aggregate signature and a group signature, and we propose a new authority-transfer system. In the signature method, a group signature scheme is used to express authority. Moreover, it transfers the authority owned by the manager to another member of the group. The difference from the group manager of the group signature is that this manager not only manages the group but also delegates authority. With the order-specified aggregate signature, it is possible to handle multiple signatures efficiently while verifying the order. We show that a safe and efficient authority-transfer system can be constructed using this new digital signature.
