The elements of {0, 1, . . . , q − 1} are called q-ary codewords of length n over a q-element alphabet. A code is a set of codewords. The Hammingdistance d(c1, c2) of two codewords c1 and c2 is the number of positions where they differ. A code C is called equidistant with distance d if the Hammingdistance of any two codewords is exactly d. Another, shorter name is: q-ary equidistant d-code. The...

Differential Power Analysis (DPA) is a powerful cryptanalytic technique aiming at extracting secret data from a cryptographic device by collecting power consumption traces and averaging over a series of acquisitions. In order to prevent the leakage, hardware designers and software programmers make use of masking techniques (a.k.a. data whitening methods). However, the resulting implementations ...

Iris Recognition is a highly efficient biometric identification system with great possibilities for future in the security systems area.Its robustness and unobtrusiveness, as opposed tomost of the currently deployed systems, make it a good candidate to replace most of thesecurity systems around. By making use of the distinctiveness of iris patterns, iris recognition systems obtain a unique mapp...

We present results related to the performance of an algorithm for community detection which incorporates event-driven computation. We de€ne a mapping which takes a graph G to a system of spiking neurons. Using a fully connected spiking neuron system, with both inhibitory and excitatory synaptic connections, the €ring paŠerns of neurons within the same community can be distinguished from €ring p...

Artificial Immune Systems (AIS) have been proposed to solve binary classification problems; distinguishing between instances of self and of non-self. For any classification system such as AIS, the choice of classifier representation used impacts substantially on the kind of classification problem that can be handled. Despite this, most classication systems such as AIS make use of only one repre...
