Abstract: Data integrity and non-repudiahon issues are common to current Web applications. To provide data integrity and non-repudiationfor these applicahons in this paper, we introduce the idea of form-signing, i.e., to digitally sign HTML form data using public-keycryptography. This tCchnology is implemented in a way that don't require significant changes to the already rurining Web architecture, it needsonly to adde a software module on the Web server side and let browsers to support Java applet. We study the main procedures of formsigning, some key points of the implementation, and further the works we need to do in the future. In our implementation, the SigningApplettakes charge of user signing of the text and verifcation of server's signature, and the SigningModule, which is added to Apache Web Server,does the server side signing.
