ASELSAN and TÜBİTAK BİLGEM conduct joint studies in the field of post-quantum cryptography. The Post-Quantum Cryptography Workshop, organized in this context, was held on December 5, 2019. In line with the decisions taken at the ASELSAN-TÜBİTAK BİLGEM Cooperation Workshop held between February 29 and March 1, 2020, it was decided to collaborate in the projects of the Ministry of National Defense and the Presidency of Defense Industry, which are likely to be projected. systems are recommended. Studies are continuing to implement hybrid methods in crypto devices to be used in secure network architecture solutions designed by ASELSAN. With the studies in this field, it is aimed that the secure network architecture solutions designed by ASELSAN, even if sufficient quantum computers are built, the systems are secure.
