Abstract

A secure transaction system in accordance with one exemplary embodiment comprising a terminal; a secure access module coupled to the terminal; and a secure embedded device coupled to the secure access module during a transaction; wherein the business logic for controlling flow of the transaction is contained within the secure access module and the secure embedded device.

Claims

1. A secure transaction system comprising:

a terminal;

a secure access module coupled to the terminal, wherein the secure access module includes a first set of business rules for performing a transaction; and

a secure embedded device coupled to the terminal during the transaction,

wherein the embedded device includes a second set of business rules for performing the transaction;

wherein the terminal routes messages between the secure access module and the secure embedded device.

2. A secure transaction system comprising:

a terminal;

a secure access module coupled to the terminal; and

an secure embedded device coupled to the secure access module during a transaction;

wherein the business logic for controlling flow of the transaction is contained on the secure access module and the secure embedded device.

3. A method of performing a secure transaction comprising:

detecting a secure embedded device that has been coupled to a terminal;

sending an operate command from the terminal to a secure access module;

executing, at the secure access module, a first set of business rules and generating a first message for the secure embedded device, wherein the first message is at least partially encrypted;

sending the first message to the secure embedded device;

executing, at the secure embedded device, a second set of business rules in response to receiving the first message and generating a second message for the secure access module, wherein the second message is at least partially encrypted; and

sending a command from the secure access module to the terminal indicating to the terminal to perform an intended function.

4. The method of performing a secure transaction of claim 3 further comprising:

executing at the secure access module, an additional set of business rules; and

evaluating any conditional rules to determine if the intended function is to be allowed.

5. A method of updating a secure embedded device in a transaction system comprising:

coupling a secure access module to a terminal;

coupling a secure embedded device to the terminal; and

receiving a message from the secure access module at the secure embedded device; and

updating at least one business rule of the secure embedded device in response to receiving the message.

6. The method of claim 5 further comprising completing a transaction in accordance with the updated business rule.

7. A method of updating a secure access module in a transaction system comprising:

coupling the secure access module to a terminal;

coupling a back end to the terminal; and

receiving a message from the back end at the secure access module; and

updating at least one business rule of the secure access module in response to receiving the message.

8. The method of claim 7 further comprising completing a transaction in accordance with the updated business rule.

9. A method of updating a device in a transaction system comprising:

coupling a secure access module to a terminal;

coupling a secure embedded device to the terminal;

receiving a message from the secure embedded device; and

updating at least one business rule of the secure access module in response to receiving the message.

10. The method of claim 9 further comprising coupling a back end to the terminal.

11. A method of updating a device in a transaction system comprising:

coupling a secure access module to a terminal;

coupling a secure embedded device to the terminal;

receiving a message from the secure access module; and

updating at least one business rule of the secure embedded device in response to receiving the message.

12. The method of claim 11 further comprising coupling a back end to the terminal.

13. A method of updating a device in a transaction system comprising:

coupling a secure access module to a terminal;

coupling a secure embedded device to the terminal;

coupling a back end to the terminal; and

receiving a message from the back end at the secure embedded device; and

updating at least one business rule of the secure embedded device in response to receiving the message.

14. The method of claim 13 further comprising completing a transaction in accordance with the updated business rule.

15. A method of communication comprising:

creating a data structure in a first application layer, the data structure indicating to a first transport layer a list of addresses that correspond to data stored in a first device and an indication of whether the data located at the list of addresses will be sent to a second transport layer in encrypted or unencrypted form;

sending the data in the list of addresses from the first transport layer to the second transport layer in unencrypted or encrypted form as indicated in the data structure;

storing the data sent from the first transport layer in memory of a second device; and

decrypting the data in a second application layer.
