校园网络环境下数字签名的研究与设计

Research and Design of Digital Signature Based on Campus Network Environment

校园网是社会信息化发展的必然产物,它担当着教学、科研、管理和对外交流等许多角色,因此其安全性非常重要。使用了一种数字签名方案来解决校园网络系统中消息传输的安全性问题,该方案是采用哈希函数MD5算法来计算消息摘要,用RSA算法实现数字签名,并用ASP实现了基于SQL的密钥管理和数字签名与验证。

The campus net is the resuh of the developing of the social information, which acts many roles like teaching, scientific studies, management and outward exchanges. In this case, its safety becomes one of important research lessons. The design adopts a kind of digital signature to solve the safety problem of message transmit in the campus network system, the strategy uses the algorithm of Hash MD5 to calculate message summary, adopts the algorithm of RSA combined. This issue also expounds the concrete process that realizes of projeet from the design of algorithm.
