LI Shu-yun · Jisuanji gongcheng · 2009
This paper dicusses the issues of authentication mechanism and framework of the digital signature system. Based on the analysis of the security gap in the authentication mechanism using digital signature,a novel authentication system combining asymmetric key cryptography and multiple watermarks technique is proposed. A robust watermark and a semi-fragile watermark are embedded in the information to carry out the functions of ID authentication and data integrity authentication. Illegal access to system,edition,and forgery of information is proven to be impossible. According to the analysis,the system’s structure is simple and the security,creditability,and authenticity are achieved.
