基于延时的物理不可克隆函数知识产权保护方法研究

Electronic watermarking technology based on Physical Unclonable Function(PUF) is a key technology of the Intellectual Property Core(IP core) protection in Field Programmable Gate Array(FPGA) industry. An advanced certified authorization management system is proposed in order to alleviate the conflict between the portability of IP core and intellectual property protection based on Delay based on Transition Probability-Physical Unclonable Function(DTP-PUF). First, DTP-PUF scheme is introduced to establish a challenge/response database with the multidimensional information, providing supporting technology for IP core intellectual property protection. Additionally, by implementing a dynamic measurement on hardware authentication and integrity, an IP core intellectual property protection scheme is designed to ensure IP core running on the authorized hardware platform. Finally, combining the authorization management cryptography and clustering analysis, a feasible grained authorization management system is proposed to meet the needs of large-scale authentication of general purpose IP cores. The results of this project will enrich the theory of PUF, and bring new ideas to the technology and practical method of intellectual property protection based on electronic watermarking. It will promote the process of building the system of intellectual property protection in China.
