Secure integrated device with secure, dynamically-selectable capabilities

A computer program product for improving security of transactions in portable devices, the computer program product embodied on one or more computer-usable media and comprising:

• computer-readable program code means for providing security function in a security core of a portable device;
• computer-readable program code means for operably connecting one or more components to the security core, wherein each component provides input/output capabilities or application processing capabilities;
• and
• computer-readable program code means for verifying authenticity of each operably connected component, such that the security core can vouch for transactions created by the operably connected components while the operably connected components remain operably connected.

A system for providing a secure, integrated device with dynamically selectable capabilities, comprising:

• a security core which provides security functions;
• one or more components;
• means for operating the security core;
• and
• means for securely operably connecting the components to the security core, such that the security core can vouch for authenticity of each securely operably connected component,
• wherein the security core and the operably connected components thereby comprise the secure integrated device.
