Systematically Ensuring the Confidence of Real-Time Home Automation IoT Systems

Abstract: Recent advances and industry standards in Internet of Things (IoT) have accelerated the real-world adoption of connected devices. To manage this hybrid system of digital real-time devices and analog environments, the industry has pushed several popular home automation IoT (HA-IoT) frameworks, such as If-This-Then-That (IFTTT), Apple HomeKit, and Google Brillo. Typically, users author device interactions by specifying the triggering sensor event and the triggered device command. In this seemingly simple softwar… Show more

Menshen [8] builds and checks the Linear Hybrid Automata (LHA) model for user rules to find violations and generate fix suggestions for non-expert users. Home-Guard [15] uses SMT models to check rules and configurations to find cross-app interference threats among smart home apps.…”

“…For example, it deines the attributes and commands of a device type, the efects on environmental variables (e.g., increasing temperature) of a command, and state transitions of a device command (i.e., what events will be generated by the execution of a command). Device/Service metadata can be constructed by analyzing the documentation of an IoT platform or provided by the platform developers or experts [28,51]. For the IFTTT platform, we construct the service metadata by crawling the web page of each service to get what triggers and actions the service supports.…”

“…7 Conversely, these works also provide several useful properties that we did not consider in iRuler. AutoTap [90] presents a method for verifying coniguration properties as expressed by novice users, and joins MenShen [28], Salus [51], and SIFT [52] in supporting automated creation and repair of rules (Rule Writing). Systems like Soteria [30], IoTSan [70], and Home-Guard (arXiv preprint only: [32]) are based on source code analysis of IoT apps and can therefore consider additional factors such as iner-grained reduction of state explosion and speciic malicious input sequences.…”

“…For instance, prior systems designed to evaluate or enforce the safety/security of home automation have one trait in common: their reliance on safety/security properties that are manually specified, either by users (e.g., in case of Menshen [37] and AutoTAP [38]) or domain experts (e.g., IoTSAN [10], Soteria [4], IoTGuard [9], or ProvThings [7]). The practical policy specification approach enabled by H lion's scenarios (Sec.…”
