A ring oscillator physical unclonable function (RO PUF) is an application-constrained hardware security primitive that can be used for authentication and key generation. PUFs depend on variability during the fabrication process to produce random outputs that are nevertheless stable across multiple measurements. Unfortunately, RO PUFs are known to be unstable especially when implemented on an Field...
Complex systems design requires a time-consuming verification process in support of the safety and maintenance requirements. In this paper, we describe an integrated verification flow of system requirements as well as system fault behaviors and fault-tolerant properties. The process converts XML-based architectural descriptions into SystemC simulation modules tied to predefined libraries. Flexible...
A physically unclonable function (PUF) is an irreversible probabilistic function that produces a random bit string. It is simple to implement but hard to predict and emulate. PUFs have been widely proposed as security primitives to provide device identification and authentication. In this paper, we propose a novel dynamic-memory-based PUF [dynamic RAM PUF (DRAM PUF)] for the authentication of electronic...
In urban areas, WiFi is the most widely-deployed portal for users to acquire the broadband access. Meanwhile, phishing AP (access point)-a rogue AP that falsifies the SSID (or even the BSSID) of a legitimate corporate AP-has caused many security problems in commodity WiFi networks. Existing research on the phishing AP detection can be divided into two categories: (1) the hardware-based approach usually...
A True Random Number Generator (TRNG) is an important security primitive used in a variety of applications including cryptographic algorithms, communication systems, simulations, etc. It is critical to be able to produce outputs consisting of fully unpredictable and unbiased bits in a cost-effective manner. In this paper, we present a robust hardware TRNG based on the Dynamic RAM (DRAM) remanence...
According to architecture characteristics of the motor control digital signal processor (MCDSP), we select standard boundary scan test which is compatible with IEEE 1149.1 as main method, and full scan test as complementary method to test whole chip. Adopted self-definition address registers, data registers, control registers together, boundary scan test makes the use of the original core circuit...
The micro architectural design space of a new processor is too huge for architects to handle with cycle-accurate simulators. Previous researches attack this problem by statistical learning methods such as Artificial Neural Networks (ANN) and statistical sampling solutions such as SimPoint. These approaches greatly reduce the simulation time while keeping the results of CPI precisely. However, all...
