Observations on NIST SP 800-90B entropy estimators Aslan, Melis; Doğanaksoy, Ali; Saygı, Zülfükar; Sönmez Turan, Meltem; Sulak, Fatih (2025-01-01) Random numbers play a crucial role in cryptography since the security of cryptographic protocols relies on the assumption of the availability of uniformly distributed and unpredictable random numbers to generate secret key...
LS-14 test suite for long sequences Akcengiz, Ziya; Aslan, Melis; Doğanaksoy, Ali; Sulak, Fatih; Uğuz, Muhiddin (2024-02-29) Random number sequences are used in many branches of science. Because of many technical reasons and their practicality, pseudo random sequences are usually employed in place of true number sequences. Whether a sequence gen...
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...
MODIFICATIONS OF KNUTH RANDOMNESS TESTS FOR INTEGER AND BINARY SEQUENCES Koçak, Onur Ozan; SULAK, FATİH; Doğanaksoy, Ali; Uğuz, Muhiddin (2018-01-01) 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...
İşletme, İktisat, Yaşam Bilimleri ve Sosyal Bilimler için Sonlu Matematik Doğanaksoy, Ali; Uğuz, Muhiddin; SAYGI, ZÜLFÜKAR; SEVİNİK ADIGÜZEL, REZAN; SULAK, FATİH; ÜRTİŞ, ÇETİN (Palme Yayıncılık, 2017-01-01)
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...
