Scan-based attacks on linear feedback shift register based stream ciphers
—In this paper, we present an attack on stream cipher implementations by determining the scan chain structure of the linear feedback shift registers in their implementations. Alt...

Smart grid monitoring for intrusion and fault detection with new locally optimum testing procedures
The vulnerability of smart grid systems is a growing concern. Signal detection theory is employed here to detect a change in the system. We employ a discrete-time linear state spa...

Multi-frequency wrapper design and optimization for embedded cores under average power constraints
This paper presents a new method for designing test wrappers for embedded cores with multiple clock domains. By exploiting the use of multiple shift frequencies, the proposed meth...

On the Complexity of Matroid Isomorphism Problem
We study the complexity of testing if two given matroids are isomorphic. The problem is easily seen to be in Σ p 2. In the case of linear matroids, which are represented over pol...

The Halting Probability in Von Neumann Architectures
Abstract. Theoretical models of Turing complete linear genetic programming (GP) programs suggest the fraction of halting programs is vanishingly small. Convergence results proved f...
