Based On The Digital Signature Of Student Result Management System

In this paper, student result management system was analyzed and studied. According to research, many schools on the results of students still use paper signature or without a direct on-line transmission of encrypted student result. The paper is the signature accomplishments of teachers will print on paper and then proceed to signature, and its shortcomings is inconvenient to carry or preserve in the online transmission of the results without encryption, it may appear on the teachers to upload the results to deny, the administrator To upload the results to tamper with and in the course of transmission by others, such as the interception of the phenomenon. The digital signature technology in the identification and authentication, data integrity, anti-denial, and other aspects of other technologies can not be replaced by the advantage that it can achieve results on the security of encryption. Therefore, the author based on the digital signature of student result management system.The system to SQL Server 2000 and VS.NET 2003 as a development platform, using B/S structure and C/S structure of a combination of systems to ensure the practicality and safety. System management of student result, class management, curriculum management, teaching information management, the private key to produce results signature verification, and other functions. B/S framework to facilitate the installation of system, browser and other characteristics of small burden, but under the framework of public and private key transmission line is very safe. Therefore, the combination of C/S structure. The system provides a public and private key pairs of plug-ins and signature verification plug-in,Let the public and private key to generate,the signatures and encryption results in the client.Teachers have a client in the public and private key, by CA's public key to encrypt the teacher's public key, and then uploaded to the server, then the server-side decryption.Furthermore, in order to resolve the future of the disputed issue of student result,on the client, using the private key of teachers to signed students' result, and then use CA's public key encryption, finally uploaded to the server, the server-side declassified by the original results. Signed in the database results while preserving the original results and the time to upload data and other information to provide the certification function, the results appear to resolve the doubt when the attribution of responsibility. Therefore, the system has the confidentiality, integrity, non-repudiation, and other aspects of security needs, has a good practical value and promote the application of value.
