Abstract. In FSE 2005, transparency order was proposed as a parameter for the robustness of S-boxes to Differential Power Analysis (DPA): lower transparency order implying more resistance. However most cryptographically strong Boolean functions have been found to have high transparency order. Also it is a difficult problem to search for Boolean functions which are strong cryptographically, and ...

objectives: the awareness of citizens leads to access to their rights. in addition to natural rights (that are noted in many investigations) people have rights that are called social rights. this survey investigates some rights that are related to the responsibilities and missions of urban management. with revising of the notion of active citizenship, citizens need purposive participation. so a...

S-boxes with better transparency order are expected to have higher side-channel resistance. For 8×8 Sboxes this is not practical, considering the costs of lookuptable implementations and deterioration of many properties like nonlinearity or delta uniformity. However, if we concentrate on the 4×4 S-box size we can observe that it is possible to obtain S-boxes with better transparency order while...

During my visit to FER I worked on several projects that relate to the activities of COST action working groups. More specifically, projects related with groups WG3-Fault attack detection and protection, WG4-Reconfigurable devices for secure functions and WG5-Validation, Evaluation, and Fault Injection. First project deals with the improvements of side channel resistance of nonlinear elements o...

We examine how corporate transparency and financing choices differ for family and nonfamily firms in the S&P 1500 Index. While transparency on average is better for firms in the S&P 500 Index than for firms in the S&P MidCap 400 and S&P SmallCap 600 indices, the improvement is much larger for family firms. Outside the S&P 500, family firms are less transparent than their non-family counterparts...

Prouff has introduced recently, at FSE 2005, the notion of transparency order of S-boxes. This new characteristic is related to the ability of an S-box, used in a cryptosystem in which the round keys are introduced by addition, to thwart single-bit or multi-bit DPA attacks on the system. If this parameter has sufficiently small value, then the S-box is able to withstand DPA attacks without that...
