Modeling Approach for Crypto Based Security Service in Embedded Environment

The aim of the paper is to investigate how to take advantage of Object Management Group's (OMG) Model Driven Architecture (MDA) for Security service design in Embedded systems. The requirements for security services do not remain constant, during its lifetime. Therefore, solutions have to evolve in order to fulfill the new requirements. This work tackles the problems related to evolution of crypto based security services. MDA concepts like Platform Independent Models (PIMs), Platform Specific Models (PSMs) and Transformation models between PIM and PSM are used in security service modeling, design and evolution. The intensive use of models helps the embedded system developer in achieving round trip engineering and subsequently preserves the efforts involved in security service development.
