One software tool for testing square s-boxes
نویسنده
چکیده
An encryption technique is widely used to keep data confidential. Most of the block symmetric algorithms use substitution functions. Often this functions use so called S-BOX matrix. In this paper author presents one software tool for testing and measuring square s-boxes. Based of information theory functions for testing static and dynamic criteria are presented. These criterions are mathematically defined for square s-boxes. Two new criteria “private criteria” a proposed and pseudo codes for they creation and testing are presented.

Security testing of session initiation protocol implementations
The mechanisms which enable the vast majority of computer attacks are based on design and programming errors in networked applications. The growing use of voice over IP (VOIP) phone technology makes these phone applications potential targets. We present a tool to perform security testing of VOIP applications to identify security vulnerabilities which can be exploited by an attacker. Session Ini...
متن کاملParameterized GUI Tests
GUI testing is a form of system testing where test cases are based on user interactions. A user interaction may be encoded by a sequence of events (e.g., mouse clicks) together with input data (e.g., string values for text boxes). For selecting event sequences, one can use the black-box approach based on Event Flow Graphs. For selecting input data, one can use the white-box approach based on pa...

In software development process, testing is one of the most important aspects and hence, software reliably is very important factor of software systems. In the last four decades many software reliability growth model based on non-homogeneous Poisson process (NHPP) have been developed which incorporates testing effort function. However, the previous models are quite helpful for software engineer...
متن کاملTesting Systems of Concurrent Black-Boxes-An Automata-Theoretic and Decompositional Approach
The global testing problem studied in this paper is to seek a definite answer to whether a system of concurrent black-boxes has an observable behavior in a given finite (but could be huge) set Bad. We introduce a novel approach to solve the problem that does not require integration testing. Instead, in our approach, the global testing problem is reduced to testing individual black-boxes in the ...
متن کاملChaotic Dynamic S Boxes Based Substitution Approach for Digital Images
In this paper, we propose an image encryption algorithm based on the chaos, substitution boxes, nonlinear transformation in galois field GF(2 8 ) and Latin square. Initially, the dynamic S-boxes are generated using Fisher-Yates shuffle method and piece-wise linear chaotic map. The algorithm utilizes advantages of keyed Latin square and affine-power-affine transformation to substitute highly cor...
