General degree requirements

A BSc degree that formally qualifies the applicant to access Master’s level studies in the country where it has been completed. This degree should correspond to at least 180 ECTS (European credits) or to a minimum of three years of full-time study.


A polytechnic degree from a Finnish University of Applied Sciences (ammattikorkeakoulu). Students with such degree might however be required to complete additional studies while studying for the Master’s degree to qualify for Master’s degree studies (see Additional studies).

Major subject specific degree requirements

The applicant’s previous degree on the basis of which s/he is seeking admission to the Master’s Degree Programme must be in a relevant field of study. For the Cryptography and Data Security major the previous degree is required to be in mathematics or mathematics related and the applicants are expected to have solid background in mathematics.

You may choose only one of the two available majors upon application. Therefore it is very important that you choose the major that is closest to the field of your previous degree. Applications with a previous degree in a non-relevant field no chance of success.

Additional studies

The contents of formally eligible applicants’ previous degrees do not always correspond to the academic level of the Programme. Therefore admitted students can be advised or required to complete additional, Bachelor level studies. These can be done while studying for the Master’s Degree, but they are not part of the degree and may extend the targeted study time. The amount of required additional studies cannot exceed 60 ECTS.

Since the language of instruction in Bachelor’s level at the University of Turku is Finnish, an applicant needing additional studies can be required to submit proof for Finnish skills during the application process (see Language requirements). In case such proof is not submitted, the applicant needing additional studies must be rejected.

Language Requirements

All applicants must prove their knowledge of English in one of the ways accepted by the Faculty.

Applicants seeking admission on the basis of a polytechnic degree from a Finnish University of Applied Sciences (ammattikorkeakoulu) may be asked to prove their proficiency in Finnish language also if they are required to complete such additional Bachelor’s level studies that are available only in Finnish.
