Strongly Secure Scan Design Using Generalized Feed Forward Shift Registers
In our previous work [12], [13], we introduced generalized feed-forward shift registers (GF2SR, for short) to apply them to secure and testable scan design, where we considered the security problem from the viewpoint of the complexity of identifying the structure of GF2SRs. Although the proposed scan design is secure in the sense that the structure of a GF2SR cannot be identified only from the ...
متن کاملShift Registers
A homomorphism of the de Bruijn graph that maps a graph of order n onto one of order n -1 and its applications to the design of nonsingular feedback shift registers are discussed. The properties preserved under this mapping suggest a new design technique whose main advantage is due to the fact that the problem of designing a desired n-stage shift register may be reduced to a problem of order n ...
متن کاملScan Design and Secure Chip
Testing a secure system is often considered as a severe bottleneck. While testability requires to an increase in both observability and controllability, secure chips are designed with the reverse in mind, limiting access to chip content and on-chip controllability functions. As a result, using usual design for testability techniques when designing secure ICs may seriously decrease the level of ...
متن کاملConcurrent Feed-forward/feed-back Design for Flexible Structures
This paper discusses the concurrent design of a feedforward time-delay filter and a linear state feed-back controller. The optimization is carried out using a quadratic cost functional which weights both, disturbance rejection and control tracking performance. A minimax optimization scheme is employed to achieve robustness with respect to parameter deviations. Analytical gradients are provided ...
متن کامل2-Adic Shift Registers
Pseudorandom sequences, with a variety of statistical properties (such as high linear span, low autocorrelation and pairwise cross-correlation values, and high pairwise hamming distance) are important in many areas of communications and computing (such as cryptography, spread spectrum communications, error correcting codes, and Monte Carlo integration). Binary sequences~ such as m-sequences, mo...
