摘要:
The invention relates to a measuring device for reading out measuring sensors disposed in a fiber optical waveguide. The measuring device comprises a grid array which distributes an input signal generated by the measuring sensors to different outputs. The transmission characteristics (12) associated with the outputs have as large an overlap region as possible so as to increase the measuring range of the measuring device.

A method for vector phase tracking a plurality of global positioning satellite carrier signals is disclosed, in which for a tracked satellite a discriminator (25) is generating phase tracking error signals at different frequencies associated with the various carrier signals of the tracked satellite and in which a multi-frequency estimation of the disturbances is performed based the phase tracking error signal supplied by the discriminator unit (28). In the method the ionospheric error is taken into account for determining output phase error signals.

摘要:
This application discusses the practical implementation of a novel security tool termed SIMPL system, which was introduced in [1]. SIMPL systems can be regarded as a public key version of physical unclonable functions (PUFs). Like the latter, a SIMPL system S is physically unique and non reproducible, and implements an individual function FS. In opposition to a PUF, however, a SIMPL system S possesses a publicly known numerical description, which allows its digital simulation and prediction. At the same time, any such simulation must work at a detectably lower speed than the real-time behaviour of S. As argued in [1], SIMPL systems have certain practicality and security advantages in comparison to PUFs, certificates of authenticity, physically obfuscated keys, and also to standard mathematical crypto technics. In [1], definitions, protocols, and optical implementations of SIMPL systems were presented. This manuscript focuses on concrete electrical, integrated realizations of SIMPL systems, and proposes two potential candidates: SIMPL systems derived from special SRAM-architectures (so called "kew designs" of SRAM cells), and implementations based on Cellular Non-Linear Networks (CNNs). This is used in a system and method for security purposes an inner structure that is accessible by a plurality of terminals, wherein the system allows a measurement on the inner structure of the system by using a challenge signal comprising a plurality of input signals applied in parallel to the terminals and by receiving a response signal dependent on a setting of the challenge signal and dependent on the inner structure of the system, wherein the system comprises the ability to process non-binary input signals, a bandwidth at the terminals and an information content ensuring a incomplete readout of the information content within a predefined access time period, a spatial and/or logical disorder of the inner structure, a non-linear relation between the input signals and output signals appearing at the terminals, and that from the knowledge of a subset of the predefined settings and of associated response signals, the response signal associated with a particular setting outside the subset is not predictable with a probability higher than the probability for guessing the response signal.
