The data transfer and data security scheme in a college students' overall quality evaluation system

Abstract

A college students' overall quality evaluation system was designed and developed based on computer and mobile blended networks. Users could do evaluation works anywhere at any time with the use of this system. Mobile office became a reality and it makes work more convenient and more efficient. HTTP protocol was adopted to transfer data between Midlet and Servlet and it makes the mobile client program to be device independent. In addition, ECDSA (Elliptic Curve Digital Signature Algorithm) was implemented in this system, and it ensures the authenticity and integrity of the data needed by the evaluation. Thus, evaluation work can be carried out objectively, fairly and efficiently by the use of this system. This paper described the data transfer scheme and the data security scheme of this system in detail. © 2012 Springer-Verlag Berlin Heidelberg.
