物理不可複製功能 – 從電路實現到安全應用

近年來隨著科技的發展以及逐漸受重視的安全需求,學界和產業界大量投入晶片指紋PUF (Physically Unclonable Functions)的研發。然而如何利用PUF優異的隨機特性輔助或搭配既有的安全功能,在產業界與學研兩界仍存有不小的落差。此一講題將依序介紹PUF的原理與運作、PUF具有的特性,以及數種不同PUF的電路實現,如早期的SRAM-PUF與近年問世的量子穿隧PUF。講題另將包含PUF的實際運用示例,並說明為何PUF在各應用場域都是不可或缺的重要安全基礎。



資安建構在於密鑰的產生方式、儲存方式、與將密鑰用於安全功能當中。因此,晶片安全的根本技術也同樣圍繞在密鑰的產生與儲存,以及建基於此的認證、加密、完整性、與不可否認性等運作。本講題將會深入剖析晶片安全信任根從硬體層一路延伸至軟體與應用層的保護,並說明如何整合以上重要功能達到極高的安全強度與健全的安全邊界(Security Boundary)。





Talk 1

PUF-From Circuit Implementation to Security Applications


With the advancement of technology and increasing security requirements, chip fingerprint -- Physical Unclonable Function (PUF) has once again become a focus. This talk will introduce several kinds of PUF, such as the SRAM-PUF and the quantum tunneling PUF that has released in recent years. Through practical examples, PUF expert Dr. Kent will explain how PUF serves as an important security foundation in specific application fields.

Chip security requirements, functions and mechanism


In addition to algorithm as an important core in chip security, protecting the encryption and decryption keys depends on the secure key storage mechanism. It involves key generation, secure storage, and proper use of keys in algorithms. It also includes operations such as signature authentication required for secure connections, data transmission integrity, data encryption, and data non-repudiation. Our experienced FAE Aken Wang of PUFsecurity will provide an overview of the usage scenarios and mechanisms related to hardware chip security before diving deeper into the topic.

The composition, function, and security operation of the root-of-trust


When it comes to chip security, the global consensus is to establish a secure and effective root-of-trust. End users may suffer financial losses, personal information leakage, and even life safety threats due to insufficient security protection. Therefore, more and more products are required to have hardware security functions. Hence, enhancing the operation security of IoT applications by leveraging the chip root-of-trust is particularly important. Our Director of R&D MY Wu will provide an in depth analysis of secure chip root-of-trust from the fundamental hardware layer protection, and discuss how to achieve high security strength and complete security boundary (Security Boundary) with the support of anti-attack digital design.

Speaker Profile

Dr. Meng-Yi Wu is the director of R&D at PUFsecurity. His expertise lies in the technology development of embedded flash memory, OTP memory and physical unclonable functions (PUF) and its derivative security chip design. Prior to joining PUFsecurity, Dr. Wu spent ten years at eMemory. In 2018, his invention, NeoPUF, won the ISSCC Takuo Sugano Award. Dr. Wu currently leads the R&D department of PUFsecurity in focusing on the development of PUF-based hardware root of trust, chip security cooperator and other security function products.
