Periodic template tests: A family of statistical randomness tests for a collection of binary sequences
SULAK, FATİH; Doğanaksoy, Ali; Uğuz, Muhiddin; Koçak, Onur Ozan (Elsevier BV, 2019-12-01)
In this work, we classify all templates according to their periods and for each template we evaluate the exact probabilities using generating functions. Afterwards, we propose a new family of statistical randomness tests, ...
R-2 composition tests: a family of statistical randomness tests for a collection of binary sequences
Uğuz, Muhiddin; Doğanaksoy, Ali (Springer Science and Business Media LLC, 2019-09-01)
In this article a family of statistical randomness tests for binary strings are introduced, based on Golomb's pseudorandomness postulate R-2 on the number of runs. The basic idea is to construct recursive formulae with com...

Generating random numbers and random sequences that are indistinguishable from truly random sequences is an important task for cryptography. To measure the randomness, statistical randomness tests are applied to the genera...
Mutual correlation of NIST statistical randomness tests and comparison of their sensitivities on transformed sequences
Doğanaksoy, Ali; Uğuz, Muhiddin; Akcengiz, Ziya (2017-01-01)
Random sequences are widely used in many cryptographic applications and hence their generation is one of the main research areas in cryptography. Statistical randomness tests are introduced to detect the weaknesses or nonr...
On the independence of statistical randomness tests included in the NIST test suite
SULAK, FATİH; Uğuz, Muhiddin; Koçak, Onur Ozan; Doğanaksoy, Ali (2017-01-01)
Random numbers and random sequences are used to produce vital parts of cryptographic algorithms such as encryption keys and therefore the generation and evaluation of random sequences in terms of randomness are vital. Test...

New Statistical Randomness Tests Based on Length of Runs
Doğanaksoy, Ali; SULAK, FATİH; Uğuz, Muhiddin; Seker, Okan; Akcengiz, Ziya (2015-01-01)
Random sequences and random numbers constitute a necessary part of cryptography. Many cryptographic protocols depend on random values. Randomness is measured by statistical tests and hence security evaluation of a cryptogr...
