基于SSL协议的表单数字签名模型研究

以电子商务软件开发为背景，研究在SSL协议基础上实现表单数字签名模型的原理与方法。首先给出SSL协议与应用集成模型，提出一种协议实现策略；进而探讨数字签名基本原理以及DSA数字签名算法，给出基于SSL协议的表单数字签名模型软件构架；最后针对提出的SSL协议实现策略给出具体实现方法，并采用体系结构描述语言ACME定义表单数字签名模型的构架模板，所提出的模型有效地克服SSL协议缺乏数字签名能力的缺陷，为电子商务提供更高的安全保障。

RESEARCH ON FORM SIGNATURE MODEL BASED ON SSL

Taking the software development of EC as background, this paper researchs the theory and method of Form Digital Signature Model based on SSL protocol. First, a integrated model of SSL and application is given, and an implementing strategy of SSL is put forward . Furthmore,the theory of Digital Signature and the DSA algorithm is discussed, and the software architecture of Form Digital Signature Model based on SSL is given, Finally, the specific implementation with the implementing strategy of protocol is put forward, and the architecture template of the software system is defined in ACME. The given model effectively overcomes the weakness of lacking the digital signature ability in SSL and provides higher security guarantee for EC.
