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.



2021/02/19 Seunghoon's paper, CENTRIS (ICSE 2021), is introduced as a news article in The Daily Swig.
The article introduces the research results of CENTRIS, which identifies modified OSS components accounting for 95% real-world popular OSS ecosystem, and its significance in terms of security and the software supply chain management.
2020/09/25 It has been published as a special feature article in the 2020 issue of 'Engineering Journal' on the theme of 'Going to Korea University Blockchain Research Institute'.
Pre-checking and preventing security vulnerabilities caused by open source code reuse in the block chain has been introduced.
2020/07/13 MBC news regarding the safety problem by the security vulnerabilities is reported at July 13, 2020.
One message can stop a fast moving scooter remotely which can be fatal to the user.
The news story is based on the analysis by CCS lab members.
