config-gen

Experiment data generator

This program will help generate test cases based on the provided constants.

Running the following command

go run main.go --secret-size 64 --config config.json

will generate config.json file for 64 bits size secrets.

It is possible to provide additional flags:

• --secret-size - secret size in bytes (48 bytes by default);
• --config - path to a config file to be generated (config.json by default).

This file contains all combinations of the algorithm's configurable constants based on provided ranges and number of elements in the range.

Changing parameters

Secret size

Secret size is set up to 48 bits and can be changed whatever is needed by changing secretSize constant in main.go file.

Algorithm constants

Algorithm constants that are alpha, M, tame, r, i and d can be configured in constants.go file.

Also, constant for ranges can be changed. Those are NumberAlphas, NumberMs, NumberTames etc. Note that setting not really high ranges will produce really vast amount of test cases. Assuming, that every range is set to 0, there will be produced 6^10 test cases that is equal to 60466176.

Config file also contains tableNum and allowWriteTable

Optimisation

Since for most of the test cases some constants are repeated, generated tables on preprocessing step (most time-consuming) could be reused. For that purpose, some test cases has allowWriteTable flag set to true, which allows to create a table to be reused on tests with similar tableNum field and allowWriteTable flag set to false.

It helps to reduce number of preprocessing really well. For instance, for that ranges that are currently set instead of 221184 preprocessing it is needed 9216. Still, it is a huge number, however, it might help to save your time. Also note, that not for all variants it is possible to optimise number of preprocessing.

Note, that tests that require table generation and can't use pre generated tables (since they don't exist) will be put first in the config file and eventually launched first.
