System and Method for Cryptographic Identification of Interchangeable Parts
First Claim
1. An anti-counterfeiting interchangeable part identification system, comprising:
- a power supply;
an identification interface device coupled to said power supply and interchangeably receiving at least one of a set of removable parts, said identification interface device having a 1-wire communication and power interface electrically connected to said power supply; and
an encryption device to be disposed on each one of said set of removable parts and powered solely by said power supply when electrically connected to said identification interface device, said identification interface device and said encryption device being electrically connected only through one lead and ground when a respective one of said set of removable parts is removably connected to said identification interface device, said one lead being a communication and power connection directly connected to said power interface when said encryption device on one of the set of parts is reliably mechanically connected to said identification interface device.

Abstract
An anti-counterfeiting identification system for a medical tubing system, including a tubing assembly having upstream and downstream tubing portions removably connected to one another in a mechanically coupled state and a mechanically uncoupled state. The mechanically coupled state is a reliable fluid tight connection of the upstream and downstream portions for fluids passing there through from the upstream portion to the downstream portion. A two-part encrypted identification assembly has a first part connected to the upstream portion and a second part connected to the downstream portion. The first and second parts are electrically connected only through one lead and ground and are electrically connected to one another only in the mechanically coupled state. Also provided are methods for identification, anti-piracy, and inventory.

12. A self-authenticating tubing set ensuring that two pieces of the set are reliably connected together, comprising:
-
a tubing set having at least first and second tubing parts, said first tubing part having a coupler and said second tubing part having a receiver removably interlocking with said coupler; a first electronic encrypted communication chip at said receiver; a power supply connected to electrical ground and to said first electronic encrypted communication chip to provide electrical power thereto; a second electronic encrypted communication chip at said coupler; said receiver having an electrically insulated communications lead connected to a communications port of said first electronic encrypted communication chip and to the electrical ground; said second electronic encrypted communication chip having; a grounding port connected to the electrical ground when said coupler and said receiver are reliably connected together; and a communications port electrically insulated from said coupler, said communications port being conductively connected to said electrically insulated communications lead when said coupler and said receiver are reliably connected together; and said first electronic encrypted communication chip and said second electronic encrypted communication chip operable to exchange encrypted data therebetween only when said coupler and said receiver are reliably connected together.

13. A method for improving security of interchangeable parts from counterfeiting, the method comprising:
-
storing encrypted unique identification data in each one of a set of 1-wire encryption devices; physically coupling a different one of the 1-wire encryption devices to each one of a plurality of interchangeable parts to be inventoried, thereby associating a particular identification data to each of the parts; and making a reliable mechanical connection between at least one of the parts to be inventoried and an encryption reader and, only upon an existence of the reliable mechanical connection; creating a reliable electrical connection between the encryption device associated with the part and an encrypted communication device of the encryption reader; reading the encrypted unique identification data associated with the part with the encryption reader; and determining an acceptance state of the part dependent upon the encrypted unique identification data read. - View Dependent Claims (14)

15. A method for preventing an end user from using unauthorized parts, which comprises:
-
supplying interchangeable parts with an encrypted identification tag; making a reliable mechanical connection between one of the parts and an encryption reading device to, thereby, create a reliable electrical connection between the encryption reading device and the encrypted identification tag; authenticating the part with the encryption reading device dependent upon encrypted identification data associated with the part; and one of; permitting a use of the part if authentication is positive; and prohibiting a use of the part if authentication is negative. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
