Abstract

Physical Unclonable Function (PUF) is a promising hardware security primitive that uses physical characteristics to provide a unique identifier for the device. PUFs are finding applications in device authentication, identification, secret key generation,key storage and also as random number generators. In this paper the main focus is to give a comparative analysis between the Delay-based and Memory-based PUFs. Several Delay-based and Memory-based PUF architectures have been proposed in the literature. The idea here is to compare these architectures in terms of performance metrics of PUF which include Uniqueness, Reliability and also in terms of conventional VLSI metrics which include area, power and delay. The results after comparison show that Memory-based PUF architectures give better performance in terms of uniqueness which is ≈ 50% (ideal 50%) but reduced reliability as compared to Delay-based PUF. Also, area overhead is less in Memory-based PUF as compared to Delay-based PUF as it avoids the need of adding extra circuitry.
基于延迟和基于内存的物理不可克隆函数的比较分析
物理不可控制功能(PUF)是一种很有前途的硬件安全原语,它使用物理特性为设备提供唯一标识符。PUF在设备认证、识别、密钥生成、密钥存储以及随机数生成器中都有应用。本文的重点是对基于延迟和基于内存的PUF进行比较分析。文献中已经提出了几种基于延迟和基于内存的PUF架构。这里的想法是根据PUF的性能指标(包括唯一性、可靠性)以及传统VLSI指标(包括面积、功率和延迟)来比较这些架构。比较后的结果表明,与基于延迟的PUF相比,基于内存的PUF架构在唯一性方面提供了更好的性能,其为≈50%(理想的50%),但可靠性降低。此外,与基于延迟的PUF相比,基于内存的PUF中的区域开销较小,因为它避免了添加额外电路的需要。
