System security approach for web-enabled HLA/RTI in the cloud simulation environment

Cloud simulation is proposed currently as a new networked modeling and simulation mode, and it has attracted wide attention from both industrial and academic communities. There is an information assurance challenge and details of simulation must be guarded from unauthorized access. However, HLA provide little security mechanism. So the security threats of the HLA/RTI protocol were analyzed. In order to address these threats, security architecture for web-enabled HLA/RTI in the cloud simulation environment were proposed based on HTTPS and public key infrastructure (PKI) technique. There were two protocols of this platform: the security record layer protocol to provide data confidentiality and integrity services, the authentication protocol to provide authentication service based on PKI authentication framework.
