Abstract

The Security-by-Contract (S×C) framework has recently been proposed to support software evolution in open multi-application smart cards. The key idea lies in the notion of contract , a specification of the security behavior of an application that must be compliant with the security policy of the card hosting the application. In this paper we address a key issue to realize the S×C idea, namely the outsourcing of the contract-policy matching service to a Trusted Third Party (TTP). In particular, we present the design and implementation of SC2 (Secure Communication over Smart Cards), a system securing the communication between a smart card and the TTP which provides the S×C matching service.
