The paper analyzes and proposes some enhancements of Ring Oscillators based Physical Unclonable Functions (PUFs). PUFs are used to extract a unique signature of an integrated circuit in order to authenticate a device and/or to generate a key. We show that designers of RO PUFs implemented in FPGAs need a precise control of placement and routing and an(More)
TELEMETRY OF physiological parameters requires miniaturrised transmitters (CRENNER et al., 1984; DABBS and NEUMAN, 1978; LAMBERT et al., 1991; RILEY, 1987). This technical note describes the receiver used in a whole system of telemetry of the human central temperature (JAY, 1990). The receiver developed provides automatic search and tracking of the(More)
The paper analyzes and proposes some enhancements of Ring Oscillator based Physical Unclonable Functions (PUFs) that are used to extract a unique signature of an integrated circuit in order to be used for device authentication purposes and/or key generation. We analyze in more details the concept developed by Suh et al. in 2007. Contrary to what authors(More)
When used in cryptographic applications, generalpurpose processors are often completed by a cryptographic accelerator – crypto-coprocessor. Secret keys are usually stored in the internal registers of the processor, and are vulnerable to attacks on protocols, software/firmware or cache memory. The paper presents three ways of extending soft general purpose(More)
In data security systems, general purpose processors (GPPs) are often extended by a cryptographic accelerator. The article presents three ways of extending GPPs for symmetric key cryptography applications. Proposed extensions guarantee secure key storage and management even if the system is facing protocol, software and cache memory attacks. The system is(More)
The paper presents hardware SoPC platform for testing performance of various TRNGs embedded in Actel FPGAs. The SoPC was implemented in the recent Actel Fusion ARM enabled FPGA device. It consists of four main blocks CoreMP7 (Actel’s soft-core industry standard ARM7 processor) for managing the SoPC, SRAM and Flash memories embedded inside the FPGA for(More)
The algorithm proposed in this paper enables the registration of two three-dimensional surface of an object when recording with a fringe-projection technique from two different viewpoints. Based on the redundancy and a distance minimization between the views, it leads iteratively to the absolute positioning of the surfaces without fringe coding. The(More)
