MEDA biochip hardware copyright protection method based on multiple PUFs

Abstract

The invention relates to an MEDA biochip hardware copyright protection method based on multiple PUFs. The method comprises the following steps of S1, generating multiple PUF excitation response pairs on an MEDA biochip by a service party, forming an excitation response pair database, and storing the excitation response pair database by the service party, S2, enabling a user to send a request for obtaining a driving sequence to the service party before using the MEDA biochip, and enabling the service party to return excitation to the chip, S3, executing excitation by the MEDA biochip to obtain response data, performing confusion calculation on the response data, and feeding back the response data to the service party, and S4, enabling the service party to judge whether the copyright of the chip sending the feedback is legal or not according to the returned response, and according to whether the chip is genuine or not, enabling the service party to return a driving sequence of the biochemical protocol with different on-chip overhead, and granting a permission for avoiding repeated verification in the later period to the genuine chip. According to the method, the hardware copyright protection reliability of the MEDA biochip can be effectively improved.

Description

technical field [0001] The invention relates to the field of MEDA biological chip copyright protection, in particular to a multi-PUF-based MEDA biological chip hardware copyright protection method. Background technique [0002] As a "lab-on-a-chip" system, digital microfluidic biochips (DMFBs) have attracted extensive attention from scholars at home and abroad. As a promising technology, DMFBs have the potential to improve biochemical experiments and healthcare processes. Because the operating object of DMFBs is microfluidics, and the degree of manual intervention is low, compared with traditional biochemical experiment operations, biochemical and medical experiments performed on DMFBs can shorten the execution time, reduce sample overhead, improve experimental accuracy and speed, and reduce human effort. caused by the error. Because of this, DMFBs can be used in experiments where samples are precious, require high precision, and require rapid response, such as neonatal di...
