摘要：Security-by-Contract (S×C) is a paradigm providing security assurances for mobile applications. In this work, we present the an extension of S×C, called Security-by-Contract-with-Trust (S×C×T). Indeed, we enrich the S×C architecture by integrating a trust model and adding new modules and configurations for managing contracts. Indeed, at deploy-time, our system decides the run-time configuration depending on the credentials of the contract provider. The run-time environment can both enforce a security policy and monitor the declared contract. According to the actual behaviour of the running program our architecture updates the trust level associated with the contract provider. We also present a possible application of our framework in the scenario of a mobile application marketplace, e.g., Apple AppStore, Cydia, Android Market, that, nowadays, are considered as one of the most attractive e-commerce activity for both mobile application developers and industries of mobile devices. Since the number of applications increases, Mobile Applications Marketplace (MAMp) sets up recommendation systems that rank and highlight mobile applications by category, social activity, etc. The S×C×T framework we propose is applied in this scenario for providing security on cus- tomers' mobile devices as well as help Mobile Applications Marketplaces to enhance their recom- mendation systems with security feedback. The main advantage of this method is an automatic management of the level of trust of software and contract releasers and a unified way for dealing with both security and trust
