智能调度指挥系统中代理签名方案研究

Study of Proxy Signature Scheme in Intelligent Dispatching System

设计了一种用于智能调度指挥系统的代理签名和代理多重签名方案,并根据业务的实际流程提出了灵活的代理权收回策略.方案解决了在特殊情况下,任务执行过程中单人和多人授权他人代替自己签名的问题,可以保持工作流执行的连贯性和有效性,满足智能调度指挥系统中代理签名多方面的安全要求.

This paper designs a proxy signature and proxy multi-signature scheme for the intelligent dispatching system. It also proposes some policies on the retrieving of the power delegation at any moment. The scheme solves the problem of the signature in the workflow, when someone needs one or more people signed papers on behalf of himself. It shows that the scheme is effective in keeping the continuity of the workflow and the security of the system.
