Abstract:

In pervasive computing, wireless devices moving from one place to another are exposed to different application service providers (ASP). Those ASP’s can violate privacy issues by collecting personal information from the device or harm other security issues by offering hostile code. It is therefore essential to know in advance whether the ASP is trusted or not before granting him access rights. Moreover, trust is a prerequisite for enabling security services like authentication, digital signatures and non-repudiation between a wireless device and any other interacting computing entity. This paper explores the possibilities to deal with trust in pervasive context aware systems and proposes a trust model to assess the trustworthiness of ASPs.
