一、随机性: NeoPUF是利用氧化层穿隧效应,在两颗并联晶体管中来实现熵源(entropy),其概念就跟投掷硬币来决定正反面相似,NeoPUF则是以电流加压,看哪一个晶体管先被打穿通电,来定义0和1的输出值。由于每一个bit即是一个有效的静态熵(static entropy),所以NeoPUF能轻易实现任何容量的entropy pool。我们可以利用NI...
For example, PUFsecurity uses NeoPUF as a static entropy to develop PUFtrng with its own logical designs. The PUFtrng features ultra-fast initial time (ready in m-sec), high-speed throughput (over 100Mbits/sec) and low power consumption (lower than 1pJ/bit), which is suitable for ...

• Entropy & reliability ensured in all specified corners (owing to adaptive control, a unique feature of our PUF) Credential generation The PUF IP ensures credential generation based on process variations properties which are unique from chip to chip, impossible to reproduce or emulate, hence ...
It uses the inherently random start-up values of SRAM as a PUF, which generates the entropy required for a strong hardware RoT. Since SRAM is a standard component available upon initial release of any process technology, the IP can be used with any foundry and process-node technology. Quidd...
Synopsys PUF uses the inherently random power-up values of SRAM as a physical unclonable function (PUF), which generates the entropy required for a strong root key. Because it uses a standard component available upon initial release of any process technology (SRAM) as a PUF source, Synopsys PU...
本文基于物理不可克隆函数PUF提出了一个实用模块化的“密钥生成器”设计,并且在FPGA设备上进行了完整的实现和评估。本文设计和实现的PUFKY,号称基于PUF的密钥生成器的第一次完整实现,包含一个PUF,一个纠错码BCH decoder和一个密码熵累加器cryptographic entropy accumulator。
Remaining portions of the PUF may be used as a entropy source for a TRNG, or other cryptographic algorithms that require high quality static entropy.Since a UID acts as the unique identifier of each device and a HUK secures applications as the root key in a key hierarchy, they both must ...
secret keys (as a keying source). Generating a UID and HUK can be a fully on-chip, internal process using a PUF-based chip fingerprint. Remaining portions of the PUF may be used as a entropy source for aTRNG, or other cryptographic algorithms that require high quality static entropy. ...
