Fast Scramblers
We consider the problem of how fast a quantum system can scramble (thermalize) information, given that the interactions are between bounded clusters of degrees of freedom; pairwise interactions would be an example. Based on previous work, we conjecture: 1) The most rapid scramblers take a time logarithmic in the number of degrees of freedom. 2)Matrix quantum mechanics (systems whose degrees of ...
متن کاملA Classification of Time Element Speech Scramblers
SUMMARY This paper contrasts four methods of time element speech scrambling (t.e.s.), which remains an extremely important cryptographic technique for narrow band channels, not least because of its robustness in poor transmission conditions such as that experienced on h.f. One method, hopping window t.e.s., although currently widely used, is increasingly being replaced by sliding window t.e.s. ...
متن کاملCryptanalysis of MUX-LFSR Based Scramblers
A recursive attack is presented that is applicable to synchronous stream ciphers consisting of a finite state machine with a linear state-transition function and a multiplexer as output function. A variant of this attack can be used to build a cheap system that bypasses on-line the scrambling of video signals as advised in [1] . 1 The Attacked System The scrambler can be described by a finite s...
متن کاملPolarization scramblers with plasmonic meander-type metamaterials.
Due to plasmonic excitations, metallic meander structures exhibit an extraordinarily high transmission within a well-defined pass band. Within this frequency range, they behave like almost ideal linear polarizers, can induce large phase retardation between s- and p-polarized light and show a high polarization conversion efficiency. Due to these properties, meander structures can interact very e...
متن کاملAn Efficient Objective Intelligibility Measure for Frequency Domain Scramblers
The main goal of a scrambler is to make a speech signal unintelligible via the permutation of its frequency subbands. In this work, we assume a sampling frequency of 8 kHz and a filter bank with 8 channels, each using a filter with 128 coefficients. With N being the number of (permutable) subbands, there are N ! possible permutations. However, not all of them are efficient [1]; this is due to t...
