Domain-specific codesign for embedded security

Systems with multiple design domains require codesign of application domains. Dedicated hardware processors implement the application domains and software integrates them. The authors use ThumbPod, a prototype embedded security application, for remote identification applications such as intelligent keys or electronic payments. The device combines security, biometrics, and networking domains. Additional software support consists of a dynamic application download using the Java application manager. Sun's K virtual machine offers an infrastructure for secure code download and execution. The virtual machine also integrates the cryptoprocessor through a native interface.
