Proposal for Security Extensions for HLA RTI in Distributed Environment

This paper describes the security extension for the High Level Architecture (HLA), an IEEE standard for distributed interactive simulation, using IPSec (IP Security) and its use for collaborative simulation development. This work is an on-going work that aims to avoid the security issues of simulation data link (such as network listening, information leaking, etc.). Security extension HLA with widely-used internet security protocols will grantee confidentiality and integrity of simulation data packets in distributed environment. This paper analyzes the critical security attributes of data link in HLA/RTI simulations and presents options for a security extension for HLA/RTI in distributed environment. Also a detailed implement of a proposed solution is presented.
