Securing Intelligent Adjuncts Using Trusted Computing Platform Technology

In [1], Balacheff et al described a new paradigm for smartcard usage called the Intelligent Adjunct model. The current increasing programmability of smartcards and development of the Internet is enabling new flexible and dynamic platforms for electronic commerce and services. In particular, the Intelligent Adjunct model combined with the use of a Trusted Computing Platform enables more flexible and more reliable network-based service development. This paper describes such a method using a hardware-based component in a computing platform to enable the establishment of a trust relationship between a smartcard and the terminal to which it is connected.
