CIM: Hardware Support for Multi-COS Isolation of RF-UCard
A Radio Frequency Universal Smart Card (RFUCard) is a novel smart card which can support multiple Chip Operating Systems (COS) on a single card and can enable radio frequency communication with readers. We are inspired from the traditional conference processes,and present the Conferencebased Isolation Model (CIM),a hardware architecture support for providing strong security isolation between multiple on-card COSes on RF-UCard. This is achieved by adding a physical isolated memory to host the running COS and its apps,whereas the other idle COSes are stored in another physical memory. In addition,the dual-core structure as well as the data bus multiplexer/demultiplexer are deployed in the CIM architecture to enforce the security isolation to be available. We have given the behavioral simulation on ModelSim by transforming the CIM architecture into a holistic VHDL model and synthesized it on FPGA.
