An Architecture of a Secure Database for Networked Collaborative Activities

Abstract: Open networks can be used for many purposes, for example, e-commerce, e-government, and so on. Different from those conventional applications, we consider networked collaborative activities, for example networked research activities. This application might be very useful and research activities could be significantly promoted. However, we must solve many security problems. Among those problems, we focus on an architecture of a secure database in this paper. The design of such an architecture is not a trivial task, since we want to use multiple data types and the appropriate security operations should be exexuted. In addition to this problem, some data may need multiple security properties. In this case, multiple security operations should be executed in a well-organized way (e.g. with the ensured order such as signature-then-encryption). Thus, we design an architecture of a secure database, considering multiple data types and various security operations.
