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. The method and system further includes utilizing the BIOS to verify at least one of the first trust relationship, the second trust relationship, or the third trust relationship using the first unit for indicating the first trust relationship, the second unit for indicating the second trust relationship, or the third unit for indicating the third trust relationship. In another aspect, the method and system are for executing an application utilizing sensitive data on a computer system. The computer system includes a master security co-processor and a secure peripheral. In this aspect, the method and system include establishing a secure channel for communication between the master security co-processor and the secure peripheral for executing a portion of the application and executing the portion of the application by the master security co-processor utilizing the secure channel.
