| Summary: | 碩士 === 長庚大學 === 資訊管理研究所 === 94 === With the booming of e-commerce, a user often accesses to multiple e-commerce web sites. At the present, the user must memorize different private identification information such as password in order to respectively access to each of the multiple web sites. Using a different password to access each web site is considered a requirement for security. This causes a burden to the user.
This thesis presents a method for user authentication. The method registers a different public key at each web site for the user. To access each web site, the user needs only an identical password and the authentication data stored in a USB to generate a digital signature to gain the access. Moreover, the user has freedom of updating the password without revising the register information. Consequently, the method provides convenience to the user without weakening security.
This master thesis further includes a system implementation to provide a justification for the feasibility of the proposed method.
