Abstract: A system and method are provided for installing and executing an applet in a secure processor. The system and method can receive the applet in non-secure data storage. The applet includes a meta-data portion and an executable portion. The meta-data portion includes a security meta-data portion, a resource meta-data portion, and a meta-data signature portion. The system and method determines whether the applet is capable of being executed by the secure processor based at least in part on the security meta-data portion and the resource meta-data portion of the applet, and if the applet can be executed by the secure processor, the applet is installed on the secure processor.

Abstract: A system and method for executing secure transactions on a computer system is disclosed. The computer system includes a memory. In one aspect, the method and system include providing a basic input output system (BIOS) on the computer system, providing a secure peripheral coupled with the computer system, and providing a master security co-processor coupled with the computer system. The BIOS includes first unit for indicating a first trust relationship with the BIOS. The secure peripheral includes second unit for indicating a second trust relationship with the secure peripheral. The master security co-processor is for processing sensitive data on the computer system and includes third unit for indicating a third trust relationship with the master security co-processor.

Abstract: A method and system for secure transactions. The method and system comprise a security co-processor and an interface for interfacing the security co-processor to a host computer system. The method and system wherein secure transaction processing is performed locally in the security co-processor and non-secure transaction processing is performed in the host computer system. The method and system further include means for providing trusted input coupled to the security co-processor. In addition, the method and system include a second interface coupled to the security co-processor for receiving sensitive data from a smart card, and a trusted display coupled to the security co-processor for providing true transaction information. One advantage of the method and system in accordance with the present invention is that transactions are protected from unauthorized intrusion and, in addition, participation is proven so that transactions cannot be repudiated.
