Research and implementation of object model in HLA

Xia Zhang, Shabai Huang, Jizhou Sun, Zhigeng Pan
2004 Fourth International Conference on Virtual Reality and Its Applications in Industry  
Object Model is important to implement purpose of HLA. OM provides a standard template to describe the abilities of simulations joining federate and the demands of outer systems.  ...  With the primary practice of navy salvage drilling simulation system, the authors give the designing of OM with an example according to the designing principle of OM.  ...  For HLA object models, the intended scope of the system description is much narrower, focusing specifically on requirements and capabilities for federate/federation information exchange.  ...

Extending the SDSI / SPKI Model through Federation Webs [chapter]

Altair Olivo Santin, Joni da Silva Fraga, Carlos Maziero
2003 Lecture Notes in Computer Science  
Classic security systems use a trust model centered in the authentication procedure, which depends on a naming service.  ...  Newer systems, with trust paradigm focused on the client and based on authorization chains, as SDSI/SPKI, are much more scalable.  ...  The X.509 PKI, for example, adopts a global naming system (X.500), which is based on a hierarchical trust model formed by Certification Authorities (CA).  ...
