摘　　要：利用校园网络可以实现校园内信息与资源的共享和网上交易.由于电子信息本身可更改,且交易时无需面对面进行,这使得假冒身份、抵赖所发送的电子信息成为可能.基于椭圆曲线数字签名算法(ECDSA)有着密钥长度小、计算负载少、节省带宽等特性,提出了一种校园CA设计,为校园网络的进一步应用,提供了安全通信机制.Utilizing the campus network, the sharing of the information,resource and online trade can be realized in the campus. Because electronic information can be altered, and trade needn't face-to-face ,so it is possible that making imitation identity and denying sent electronic messages. Therefore this paper presents a design of CA in campus based on ECDSA with reductions in storage space, bandwidth and smaller length key in order to provide security communication on network of campus for more applications.
