Who We Are

Software Technologies Research Institute (YTE), which carries out R&D activities in the field of software technologies that our country needs; is a TÜBİTAK BİLGEM institute that provides software development, digital transformation, software quality monitoring and consultancy services.


Technology & Solutions

Software Development

In collaboration with public institutions and organizations, R&D-focused, strategic, sensitive, and critical software projects are being developed using new technologies and innovative approaches. These projects embrace a quality-oriented approach, aiming to achieve customer satisfaction through highly mature processes and a skilled workforce, ultimately generating value for both institutions and citizens.

Digital Transformation

In order for public institutions and organizations to provide high service quality to citizens with an efficient, effective and transparent structure, activities are carried out to determine the necessary digital maturity levels, to ensure business and process-based transformation, and to reveal the software requirements suitable for this transformation.

Quality Management and Process Improvement

Knowledge gained through the application and dissemination of the best practices used in process improvement in international standards and approaches in line with the processes developed in accordance with CMMI DEV V2.0 Level 5 requirements, Project Management Institute (PMI) practices and ISO 9001:2015, ISO 27001:2017 standards and experiences are transferred to public institutions and organizations to contribute to the software development ecosystem.


Comparison of REST API and gRPC Architectural Styles

gRPC and REST API are two different architectural styles commonly used in modern application development. While gRPC, developed by Google, is focused on performance and efficiency, REST API is a more generic architecture built on usability and simplicity. gRPC converts data into binary format using a serialization format called Protobuf, enabling high-speed communication with low memory usage. REST API, on the other hand, usually uses the JSON format to transfer data. The purpose of this paper is to guide the reader in choosing the right architectural style by considering factors such as application needs, performance, data integrity and platform independence.
Spring Framework

Spring Framework is an open source development platform that provides comprehensive infrastructure support for developing Java applications. It has recently increased its popularity among current technologies and has become one of the most preferred application frameworks. Spring Framework is recognized as one of the most important tools used when developing applications in Java language. This framework aims to eliminate the difficulties often encountered during the development of Java applications. It facilitates the process and stages of application writing by eliminating the effort of writing the entire program code from scratch. Within the scope of this study, topics such as Spring Framework concepts, features, areas where it can be used, what can be done, and preferences are discussed in general.
Use of Authentication Engines

There are many technologies for user authentication and authorization. These include Apereo CAS, Keycloak, Gluu, Okta, Shibboleth, WSO2, AWS Cognito. In this study, Apereo CAS and Keycloak technologies, which provide secure single sign-on (SSO) services for web-based applications due to their open source, extensibility and scope, are examined. Alternatives for user login and authorization technologies, which are an important part of software projects, have been researched and the integration of these alternative technologies with the Spring Framework has been tested. This study is handled in a framework that can be used by all public institutions and private sectors that want to add a security layer to their software projects.

(IZE) Artificial Intelligence Institute

Artificial Intelligence Institute is the first institute established within the scope of TUBITAK centers and institutes, which cuts the sectors and research fields horizontally and focuses directly on the emerging technology field. For this reason, it constitutes an innovative model in terms of both the open innovation and co-development approach of the institute and its focus on emerging technology.

Artificial Intelligence Institute aims to develop core technologies in the field of artificial intelligence and bring these innovations from the forefront of science to the use of the industry as soon as possible. Focusing on the transformative potential of artificial intelligence, it will continue to play its part in pioneering efforts to create and sustain artificial intelligence-based innovation, growth and productivity in Turkey. Working with industry and public institutions in Turkey, together with other organizations within the artificial intelligence ecosystem, spreading the use of artificial intelligence and increasing the workforce specialized in this field are among its primary goals.

Competence Centers

MILSEC 4 - Secure IP Terminal


While the MİLSEC-4 terminal offers an up-to-date solution for next-generation secure communication (voice, data and video) in IP networks, it provides an uninterrupted communication service by maintaining the compatibility of secure voice communication in PSTN networks with PSTN secure phones in use.

Configuration, surveillance and software update processes of MILSEC-4 terminals are carried out securely remotely using the Security Management Center (GYM). MİLSEC-4 terminal is capable of IP Network Key Loading (IPAAY) through secure communication with GYM without the need for an additional device.

MİLSEC-4 terminals are interoperable with MİLSEC-1A and MİLSEC-2 phones and offer the opportunity to replace MİLSEC-1A and MİLSEC-2 phones without interruption in the gradual transformation of PSTN networks to next generation IP networks.


  • End-to-end secure voice communication in PSTN networks
  • End-to-end secure voice, image and data transmission in IP networks
  • NATO SCIP compliance on IP networks
  • Compatibility with commercial SIP products
  • Interoperability with MILSEC1A and MILSEC2 secure phones
  • National and AES crypto algorithms
  • Remote software update
  • Easy operation with touch screen
