Computer & Communication Security Laboratory (CCS Lab) was established in 2004 for the purpose of studying security problems and proper countermeasures. The members of CCS Lab are pursuing research on system security and network security. We take part in activities related to computer security and cooperate with professors and researchers inside and outside the country for research advances. We continue to publish the results of our researches and projects in the major international journals and conferences.
