At the keynote speech, Ju Myung-geon, Honorary Chairman of Sejong University, said, "The importance of cybersecurity cannot be overstated," adding, "We must ensure thorough internal stability and take a step further to break down interdisciplinary boundaries so that cybersecurity is applied across all fields."

The first presentation was given by Professor Lee Jong-hyuk of the Department of Information Security at Sejong University on the topic of air-gap jumping. Air-gap malware refers to data theft in a network-isolated environment from the attacker's perspective. Professor Lee introduced methods for data theft in systems without network connections, such as national critical infrastructure or military confidential facilities, and emphasized the importance of offensive security, which means security from the attacker's perspective.

Professor Lee Kwang-soo of the Department of Information Security at Sejong University gave a presentation on functional encryption. He stated, "Functional encryption is a new paradigm of public-key cryptography where the sender encrypts a message and the receiver, upon decryption, outputs the result of a function applied to the message," adding, "Using functional encryption enables flexible access control over ciphertexts and can be applied to interesting environments such as data mining on sensitive data requiring user privacy."

Professor Kang Ji-won of the Department of Computer Engineering at Sejong University explained memory kill switch technology for loss of control in unmanned mobile vehicles. Professor Kang said, "When a military drone loses control in enemy territory, it is necessary to develop hardware-based kill switch technology that autonomously assesses the situation and quickly and completely physically erases critical information stored in memory (chips)."
