摘　　要：研究了供应链链式代理签名的问题,给出了一种具体的实现算法。首先,对供应链上企业进行了明确标识;然后,给出链式代理签名的具体算法;最后,对算法的正确性、特点进行了证明和分析。该算法基于大数分解和离散对数难题来构造,能够很好地密切供应链上企业间关系,提供整个供应链的合同信息传递效率。算法本身的设计解决了电子商务中的机密性、完整性、可用性和不可否认性问题。算法的设计具有一定的经济性,在供应链通信网络上具有通信效率高,能够明确经济实体的责权关系。The problem about proxy list-style signature in supply chain is studied, a specific application algorithm is proposed.Firstly, the enterprises on supply chain are directly marked. Then, we describe the detailed list-style proxy algorithm. Lastly, the correctness and specialty of the algorithm are proved and analyzed.The algorithm is based on big-number factor-decompose and discrete logarithm puzzle.It can make the relation between enterprises on supply chain more friendly. At the same time, it can improve the efficiency of transaction information’s transmission on the whole supply chain. The privacy,integrality,usability and undeniability in electronic business can be resolved by the algorithm’s own frame. The algorithm’s frame is economy. The transmission efficiency of the algorithm is high on the supply chain net,and it can directly point out the relation between obligation and right of the economy entities.
