Abstract

An access system is disclosed that provides secured access to a security area. In some embodiments of the present invention, the access system includes an input device that is accessible to a user and capable of reading an authentication and/or identification information provided by the user; a standard signal control panel coupled to the input device for evaluation of the information provided by the user, the control panel being located in a secure area remote from the input device; and a signal processor coupled between the input device and the standard signal control panel, the signal processor being located in the secure area, wherein the input device provides data in a secured communication channel to the signal processor and the signal processor, in response to the data provided by the input device, provides the data to the standard signal control panel utilizing a standard signal. In some embodiments, the standard signal control panel may be a Wiegand or Magnetic-strip control panel. In some embodiments, the secured communications channel may be an RS422, RS485 or a TCP/IP protocol channel.

Claims

1. An access system, comprising:

an input device that is accessible to a user and capable of reading authentication and/or identification information provided by the user;

a standard signal control panel coupled to the input device for evaluation of the information provided by the user, the control panel being located in a secure area remote from the input device; and

a signal processor coupled between the input device and the standard signal control panel, the signal processor being located in the secure area,

wherein the input device provides data in a secured communication channel to the signal processor and the signal processor, in response to the data provided by the input device, provides the data to the standard signal control panel utilizing a standard signal.

2. The system of claim 1, wherein the data provided by the input device in the secured communication channel includes a dynamic element.

3. The method of claim 2, wherein the dynamic element is used to ensure that a replay attack cannot be used to gain unauthorized access to an entrance portal.

4. The system of claim 1, wherein the standard signal is chosen from a set consisting of Wiegand signals, Mag Stripe signals, and Bar Code signals.

5. The system of claim 1, wherein the signal processor is co-located with the control panel in the secure area.

6. The system of claim 1, wherein the input device includes a smart card reader.

7. The system of claim 1, wherein the input device includes a PIN pad.

8. The system of claim 1, wherein the input device includes a biometric device.

9. The system of claim 1, further including a host computer coupled to the input device and the standard signal control panel, the host computer communicating parameters to the input device and the standard signal control panel through secured channels.

10. The system of claim 1, wherein the communications channel is secured using at least one of the following methods:

encryption of the transmitted information; and

/or

authentication of the transmitted information using a digital signature; and

/or

the use of a dynamic element, shared by input device and the signal processor to protect against replay attacks.

11. The system of claim 1, wherein the input device communicates with the signal processor in a self-clocked non return to zero or Di-phase communication.

12. An access system comprising:

means for receiving authentication and/or identification information provided by a user;

means for securely transmitting the authentication and/or identification information provided by the user;

means for receiving the securely transmitted information; and

means for providing the received information to a standard control panel using standard signals; and

means for controlling access to a secured area based on the information received by the standard control panel.

13. The system of claim 12, wherein the authentication and/or identification information provided by a user includes at least one of smart card information, biometric information, or PIN information.

14. The system of claim 12, wherein means for receiving authentication and/or identification information provided by a user further includes means for combining additional dynamic information with the authentication and/or identification information.

15. The method of claim 14, wherein the additional dynamic information is based on temporal information generated contemporaneously with the authentication and/or identification information provided by the user.

16. The system of claim 12, wherein means for securely transmitting the authentication and/or identification information provided by the user further includes means for digitally signing and/or encrypting the information.

17. The system of claim 12, wherein means for receiving the securely transmitted information further includes means for decrypting and/or authenticating the received information.

18. The system of claim 12, wherein means for means for providing the received information to a standard control panel using standard signals further includes means for translating the received information to a format compatible with standard control panel inputs.

19. The method of claim 18, wherein the standard control panel inputs are chosen from chosen from a set consisting of Wiegand signals, Mag Stripe signals, and Bar Code signals.

20. An access method comprising:

receiving authentication and/or identification information provided by a user through an input device;

securely transmitting the authentication and/or identification information provided by the user;

receiving the securely transmitted information;

providing the received information to a standard control panel using standard signals; and

controlling access to a secured area based on the information received by the standard control panel.

21. The method of claim 20, wherein the authentication and/or identification information provided by a user through an input device includes at least one of smart card information, biometric information, or PIN information.

22. The method of claim 20, wherein receiving authentication and/or identification information provided by a user through an input device further includes combining additional dynamic information with the authentication and/or identification information.

23. The method of claim 22, wherein the additional information is generated by the input device.

24. The method of claim 22 wherein the additional dynamic information is based on temporal information generated contemporaneously with the authentication and/or identification information provided by the user.

25. The method of claim 20 wherein securely transmitting the authentication and/or identification information provided by the user further includes digitally signing and/or encrypting the information.

26. The method of claim 25, wherein the digital signing and/or encryption of the information is performed by the input device.

27. The method of claim 20, wherein the steps of receiving the securely transmitted information and providing the received information to a standard control panel using standard signals are performed by a signal processor.

28. The method of claim 20, wherein receiving the securely transmitted information further includes decrypting and/or authenticating the received information.

29. The method of claim 20 wherein providing the received information to a standard control panel using standard signals further includes translating the received information to a format compatible with standard control panel inputs.

30. The method of claim 29, wherein the standard control panel inputs are chosen from chosen from a set consisting of Wiegand signals, Mag Stripe signals, and Bar Code signals.

31. The method of claim 27, wherein the input device communicates with the signal processor using self-clocked non return to zero or Di-phase communication.
