In this paper we show how deductive and abductive reasoning in distributed authorisation can be efficiently ported to Android. Such logical-inference processes prove to be important tools due to the intrinsic autonomic-nature of these mobile devices. Both deduction and abduction are represented by using Constraint Handling Rules (CHR), a high-level declarative constraint programming-language, and implemented in JCHR (CHR embedded into Java). To represent credentials we elaborate on RTW, a weighted Role-based Trust-management family of languages: CHR programs are developed after such languages. In general, having weights associated with credentials leads to a more informative reasoning, for instance, access can be granted only if the total uncertainty is less than 20%.

Abstract
In this paper we show how deductive and abductive reasoning in distributed authorisation can be efficiently ported to Android. Such logical-inference processes prove to be important tools due to the intrinsic autonomic-nature of these mobile devices. Both deduction and abduction are represented by using Constraint Handling Rules (CHR), a high-level declarative constraint programming-language, and implemented in JCHR (CHR embedded into Java). To represent credentials we elaborate on RTW, a weighted Role-based Trust-management family of languages: CHR programs are developed after such languages. In general, having weights associated with credentials leads to a more informative reasoning, for instance, access can be granted only if the total uncertainty is less than 20%.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
