Department of Software Engineering was founded in 2005 as the first department in Ankara in Software Engineering. The recent developments in current technologies such as Artificial Intelligence, Machine Learning, Big Data, and Blockchains, have placed Software Engineering among the top professions of today, and the future. The academic and research activities in the department are pursued with qualified faculty at Undergraduate, Graduate and Doctorate Degree levels. Our University is one of the two universities offering a Doctorate-level program in this field. In addition to focusing on the basic phases of software (analysis, design, development, testing) and relevant methodologies in detail, our department offers education in various areas of expertise, such as Object-oriented Analysis and Design, Human-Computer Interaction, Software Quality Assurance, Software Requirement Engineering, Software Design and Architecture, Software Project Management, Software Testing and Model-Driven Software Development. The curriculum of our Department is catered to graduate individuals who are prepared to take part in any phase of software development of large-scale software in line with the requirements of the software sector. Department of Software Engineering is accredited by MÜDEK (Association for Evaluation and Accreditation of Engineering Programs) until September 30th, 2021, and has been granted the EUR-ACE label that is valid in Europe. This label provides our graduates with a vital head-start to be admitted to graduate-level programs, and into working environments in European Union countries. The Big Data and Cloud Computing Laboratory, as well as MobiLab where mobile applications are developed, SimLAB, the simulation laboratory for Medical Computing, and software education laboratories of the department are equipped with various software tools and hardware to enable our students to use state-of-the-art software technologies. Our graduates are employed in software and R&D companies (Technoparks), national/international institutions developing or utilizing software technologies (such as banks, healthcare institutions, the Information Technologies departments of private and public institutions, telecommunication companies, TÜİK, SPK, BDDK, EPDK, RK, or universities), and research institutions such TÜBİTAK.

Abstract

Anlık mesajlaşma, iletişim aracı olarak yaygın olarak benimsenmiştir. Çoğu anlık mesajlaşma uygulaması, üstverileri toplar veya sızdırır. Birçok insan, çağdaş ve popüler anlık mesajlaşma uygulamalarının getirdiği güvenlik ve kişisel gizlilik konularının farkında değildir. Hem güvenli hem de tamamen anonim olan merkezsiz ve kullanımı kolay mesajlaşma sistemi öneriyoruz. Bir saldırganın tehlike yaratabileceği merkezi sunucular olmadığından, önerilen sistem sansüre karşı dayanıklıkdır. Ethereum ortamında hafif bir istemci aracılığıyla çalışan uygulamayı, Android ortamında gerçekleştirdik. Önerdiğimiz uygulamanın yalnızca güvenli ve anonim değil aynı zamanda pratik de olduğunu göstermek için başarım değerlendirmesini yaptık.
Instant messaging has seen wide adoption as a means of communication. Most instant messaging applications either actively collect or leak metadata. Most people are not aware of the security and privacy issues that come with modern popular instant messaging applications. We propose a decentralized, easy-to-use messaging system that is both secure and completely anonymous. It is censorship-resistant as there are no centralized servers for an attacker to compromise. We have implemented the application on the Android platform and runs a light client on the Ethereum platform. We have evaluated the performance of our proposed application to show that it is capable of not only being secure and anonymous but also practical.
