For the purpose to ensure the implementation of the plan of tasks for the first half of 2016 (10 appendixes) of the meeting of the Presidium of the Cabinet of Ministers (pr. №5 from 25 January 2016), as well as on the proposal of the Ministry of Development of Information Technologies and Communications of the Republic of Uzbekistan the creation of the faculty "Information security"and the specialized departments as part of the faculty, as well as for the approval of this proposal in the Council on the technical safety of the Ministry of ICT on the development of information technologies and communications of the Republic of Uzbekistan (pr. №3 from 18 July, 2016) and by the decision of the Tashkent University of information Council technologies (dec. №1 (661) from 29 August 2016) established the Faculty of "Information security" with the specialized departments of "Providing information security" and "Cryptology and discrete mathematics" at the department "Information security" of the faculty "Computer engineering".

A specialized department “Cryptology and discrete mathematics” was created within the faculty. In 2019, the department of “Cryptology and Discrete Mathematics” was renamed the department of “Cryptology” (order of the university rector No. 439 dated March 7, 2019).

In 2016-2019, the department was headed by candidate of technical sciences Akhmedova Oydin Pulatovna. Since February 13, 2019, the department has been headed by Doctor of Philosophy in Technical Sciences Khudoykulov Zarifjon Turakulovich.

Professors and teachers of the department conduct classes for students enrolled in bachelor's and master's programs. Teachers of the department give lectures and conduct practical classes in general and selective subjects.

The teaching staff of the department published textbooks, methodological instructions for laboratory and practical classes, and a number of lecture materials on the disciplines taught.

The main activity of the department is training students in cryptographic methods of information security. The department trains specialists capable of solving the most important tasks to ensure the national security of the Republic in the information sphere, and, above all, in executive authorities.
