This paper presents the first formal security model for the Flash platform. Our formal model instantly reveals that the run-time checks performed by the Flash runtime are not sufficient to enforce data integrity \u2013 we present simple example programs that are vulnerable to attacks. We then develop a static type system for Flash programs that lets programmers specify fine-grained trust relationships, and we show that, combined with the run-time checks already performed by the Flash runtime, well-typed programs cannot violate data integrity at run-time.<\/p>\n","protected":false},"excerpt":{"rendered":"
