Abstract
Against the background of continually growing problems of product piracy, in particular due to the further expansion and liberalization of international trade, there is great demand for automated and reliable inspection of the authenticity of products. Thus, methods and systems are provided for inspecting a product as an original product of a product producer by authenticating at least one RFID (Radio Frequency Identification) tag allocated to the product using an asymmetrical challenge response protocol.
Claims12
A method for authenticating a product using an asymmetrical challenge response protocol, comprising:
- reading a digital certificate wirelessly transmitted by a Radio Frequency Identification (RFID) tag associated with a product, the digital certificate comprising a public key,
- accessing an electronic delivery note assigned to the RFID tag or to the product,
- generating a challenge based on the public key,
- transmitting the challenge wirelessly to the RFID tag,
- receiving wirelessly from the RFID tag a response to the challenge, the response being generated by the RFD tag based on a secret key that assigned to the RFID tag,
- verifying the response received from the RFID tag to determine an authentication result, and
- associating the authentication result with the electronic delivery note assigned to the RFID tag or to the product.
A Radio Frequency Identification (REID) reader configured to authenticate a product using an asymmetrical challenge response protocol, comprising:
- electronics programmed to:
- read a digital certificate wirelessly transmitted by an RFID tag associated with a product, the digital certificate comprising a public key,
- access an electronic delivery note assigned to the RFID tag or to the product,
- generate a challenge based on the public key,
- transmit the challenge wirelessly to the RFID tag,
- receive wirelessly from the RFID tag a response to the challenge, the response being generated by the RFID tag based on a secret key that assigned to the RFID tag,
- verify the response received from the RFID tag to determine an authentication result, and
- associate the authentication result with the electronic delivery note assigned to the RFID tag or to the product.
A system for authenticating a product using an asymmetrical challenge response protocol, comprising:
- a Radio Frequency Identification (RFID) tag associated with a product, the RFID tag storing a digital certificate comprising a public key, and a secret key that assigned to the RFID tag;
- and
- a Radio Frequency Identification (RFID) reader comprising electronics configured to:
- wirelessly receive the digital certificate from the RFID tag,
- access an electronic delivery note assigned to the RFID tag or to the product,
- generate a challenge based on the public key,
- transmit the challenge wirelessly to the RFID tag,
- wirelessly receive from the RFID tag a response to the challenge, the response being generated by the RFID tag based on the secret key assigned to the RFID tag,
- verify the response received from the RFID tag to determine an authentication result, and
- associate the authentication result with the electronic delivery note assigned to the RFID tag or to the product.
