How does CSSI TPM plug-in work?

At the core of the charismathics CSSI TPM plug-in solution is a version 1.2 compliant TCG Software Stack that supports TPMs from all the major vendors, including Infineon, Atmel, ST Microsystems and Broadcom. Application support is provided either through a Microsoft CryptoAPI compliant CSP — for applications that support CryptoAPI, such as Microsoft Outlook, or a PKCS#11 component - for applications such as Firefox. These same interfaces can be used by card management applications to load keys and certificates onto the cards, and manage the user PIN.
