Domain-specific codesign for embedded security

Abstract

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.
