| Summary: | 碩士 === 國立中正大學 === 資訊工程研究所 === 88 === We have designed and implemented a security model for a distributed
class algebra OODB (Object-Oriented Database). This has a function
similar to that of a security system for a building. Its function is to decide
whether a client can invoke a given method. There are three parts of the
security model. The first part invokes the authentication between the server
and the client. The second part invokes checking the permission of clients
to invoke certain methods. This is the most important part. We use 3-tier
management architecture. The top tier has "roots". They can manage all
permissions. The middle tier has "groups". There are many groups, and
they have a hierarchy. They can manage their own group members or
members of any subgroups. The bottom tier is the "clients". They can
manage the permissions of the objects that they have created. The third
part involves how to invoke methods via several different servers on the
INTERNET.
