Abstract

We explore the challenges for making the programming interfaces for embedded devices open and safe, and present a prototype architecture for delivering verified programs using barcodes. In particular, we consider programs for microwave ovens, which provide a basic open API for controlling cooking times. In our architecture, recipes are written in Java, and their safety properties are formally verified using the model checker Spin. We use off-the-shelf utilities for compressing the byte code, and use two-dimensional barcodes for program delivery. We report on experiments that demonstrate the feasibility of the proposed architecture for predictability and delivery.
