Design and analysis of SRAM-based PUF primitives in nanoscale CMOS technolgies

随着物联网承诺分布式和无监督移动计算设备数量的激增，用于防伪和安全通信的轻量级设备认证协议变得至关重要。物理不可克隆函数（PUF）原语最近被提出作为替代非易失性存储器（容易受到物理攻击）的一种手段，用于为基于安全的函数生成和存储加密密钥。本研究方案解决了设计基于静态随机存取存储器（SRAM）的PUF电路块所涉及的可靠性问题，然后将其集成到基于硬件的安全子系统的认证电路中。本提案的主要研究目标是：(i)基于sram的PUF原语的设计，（ii）设计方法的开发，以减轻工艺，电压和温度引起的变化的影响-更多问题

As the Internet of Things promises a proliferation in the number of distributed and unsupervised mobile computing devices, lightweight device authentication protocols for counterfeit prevention and secure communication becomes paramount. Physically unclonable function (PUF) primitives have recently been proposed as a means for replacing non-volatile memories (which are prone to physical attacks) for generating and storing cryptographic keys for security-based functions. This research proposal addresses the reliability issues involved in designing a static random access memory (SRAM)-based PUF circuit block, and then integrates it into an authentication circuit for use in a hardware-based security subsystems. The key research objectives of this proposal are: (i) the design of an SRAM-based PUF primitive, (ii) the development of design methodologies to mitigate the impact of process, voltage, and temperature induced variability - issues more prevalent in nanoscale CMOS technologies, and (iii) the realization of the SRAM PUF primitive in a low-overhead device authentication system.
