  Array Generation Analytic The 2D entropy indicator showed problems in the existing algorithms of the Czech Entropy PRNG application. If the basic version of generating "random" numbers gives such a distribution on the plane The problems of distributing points on a plane are obvious. If you connect the options PRNG Mode 2 and Encalibration Mode 2 , the distribution will become different The number distribution is different, but not better (for encryption) Connecting the PRNG MultiMode 3 option gives a different distribution of numbers on the plane. Better than the second picture. But even on a short array it is noticeable that the generation of numbers needs to be improved. This can be done through post-processing. The corresponding module is currently under development. It is clear that the ability to evaluate the resulting arrays of numbers is very important for PRNG We will also develop 2D indicators of other types Android Java Programming

  No putterns I am currently correcting the errors and inaccuracies found. An idea appeared on how to eliminate patterns in the generated array (2D entropy). This will result in an array of more than 60 numbers. Size will vary. Czech Entropy PRNG Czech XOE Calculator

 Czech Entropy PRNG A method has been developed for the hidden diffusion of numbers into any files or data blocks. Requests to the server, sending or receiving data, binary files. New methods for expanding the source data for PRNG have been invented. The methods do not depend on the hardware platform and Android version. You can make any expansion coefficients. The resulting binary code depends very much on the parameters chosen and the number of conversion levels. https://apkadmin.com/n4g9a5vm9m78/CzechEntropy.apk.html Android JAVA

  Expansion module The development of the third source data extension module for the Czech Entropy PRNG application has begun. Unlike the TTS-based expansion module currently used, the new module will be hardware-independent (and independent of the Android version). The sender and recipient of messages will be able to use different smartphones. The module will be added. Those. It will remain possible to use the previous data expansion algorithms.

  2D entropy A prototype of a module for displaying 2D entropy has been created. Allows you to assess the quality of the generated array of numbers. Of course, a small volume of passive (60 numbers) is not enough to assess the quality of a “random” number generator. But it allows you to discard arrays of clearly low quality. For the screenshot, a “basic” array of numbers with minimal post-processing was used. For such an array, radius estimation and correction can be used. Czech Entropy APP

Czech XOR Calculator A module (Java method) has been developed for applying masks to an array of numbers (generated array) before using it as input data for the next session of generating “random” numbers. The module allows you to select values from the entire array that will be supplied to the “input” of the application (PASTE mode) by insertion. You can also change the order of numbers in the supplied array and set some repetitions. For now, the mask will be used inside the application. The user will then be presented with an interface for personal editing and creating masks. The mask will be stored in resources if it needs to be used several times. Czech Entropy PRNG The development of an Android application algorithm for non-public transmission of encrypted data has begun. Czech Entry .The basic principle is that the data is converted into an object that "has nothing to do with numeric data"

  Single-bit Density The module for analyzing and displaying one-bit density in an array of numbers works like this Czech Entropy PRNG

  Singe bit density A module of analysis and display of a single -bit density in an array of numbers has been developed. Testing Czech Entropy PRNG

  Android PRNG A second activity with online guidance has been added to the application. In the next version, the possibilities for manually selecting parameters for generating “random” numbers will be expanded. Work continues on the mask module for transmitting data to the generator input (MCULTIMODE mode) Download page:  https://appsenjoy.com/en/ZsyGTTW0VHkiih9/file Czech Entropy PRNG
