More Information
Summary:A multiple application smart card (102) uses hardware firewalls (130) and an internal communications scheme to isolate applications from different service providers. A first application (116) from a first service provider is stored within a first supplemental security domain (SSD) (126) of a memory device on the multiple application smart card (102). A second application (116) from a second service provider is stored within a second SSD (128) of the memory device. A hardware firewall (130) is located between the first and second applications (116) of the first and second SSDs (128). The hardware firewall (130) prevents direct data access between the first and second applications (116) of the first and second SSDs (128).
