Effective novel anti-counterfeiting method based on physical unclonable function

Abstract

The present invention relates to an effective novel anti-counterfeiting method based on a physical unclonable function. The method comprises: storing a master key MSK, ID and an instruction C sent to an RFID tag in a server-side database; and storing critical auxiliary data W in ROM of the RFID tag, storing the master key MSK and instruction C by a hardware security module in a reader so as to implement off-line authentication and the security of information protection. By determining a response Y (C) generated by stimulating PUF by virtue of the instruction C and a private-key SKID calculated by the auxiliary data W, then by virtue of a message authentication code generated by hashing, the message authentication code is compared with the message authentication code corresponding to the private-key SKID obtained by hashing in a registration phase to verify whether the two are equal or not so as to implement product authentication. The method has the characteristics of being relatively low in storage complexity, relatively high in query efficiency, simple and convenient in authentication process, small in calculation cost, hard to be maliciously cloned and difficult to be stolen in critical information and the like.

Description

technical field [0001] The invention relates to the anti-counterfeiting field of products, in particular to an effective new anti-counterfeiting method based on a physical unclonable function, which utilizes a physical unclonable function (PUF) to realize RFID anti-counterfeiting. Background technique [0002] As we all know, the purpose of anti-counterfeiting technology is to achieve anti-counterfeiting of products, which requires certain countermeasures. If such measures can effectively verify the authenticity of products, and at the same time, it is difficult to be forged or copied by unauthorized attackers, this will be achieved. To achieve the protection of legitimate goods, that is, to achieve the so-called anti-counterfeiting. The more traditional anti-counterfeiting technologies include: watermarking technology, barcode technology, invisible image anti-counterfeiting technology and serial number technology, etc. After years of use of these technologies, there are alr...

Problems solved by technology

[0006] To sum up, if only RFID is used to construct an anti-counterfeiting solution, it is fundamentally difficult to resist cloning attacks. If the anti-counterfeiting solution designed with public key technology, RFID and PUF is not high in the storage complexity of the server, the calculation cost of the public key on the database side High and difficult to achieve

In the anti-counterfeiting scheme using simple challenge and response mode, the server needs to store the challenge and response data pairs of each product, which is not only not safe enough, but also the storage complexity of the server in this type of scheme is high, and the query of the server also needs to be relatively complex. high computational load
