Embedded Java Security provides a comprehensive analysis of the security aspects of Embedded Java, particularly in the context of mobile devices. The book examines the security models of the Java 2 Standard Edition and highlights the challenges posed by the limited resources in embedded systems. It introduces the main components of the Embedded Java platform to facilitate a better understanding of the architecture. Additionally, the effectiveness of the security model is analyzed through an evaluation of the security features, with results presented within the framework of the MEHARI method for risk analysis and the Common Criteria method for security assessment. This security evaluation aims to identify areas that require security enhancement. The book is aimed at both researchers and practitioners, offering deeper insights into the challenges of Embedded Java security and the security of mobile devices.
