약 40년 전 설계된 현재의 인터넷은 보안 취약점, 사용자 이동성 지원 부족, 효율적인 콘텐츠 전달의 어려움 등 많은 문제점에 직면하고 있다. 특히, 스마트폰, 스마트TV 등과 같은 인터넷 접속 디바이스의 폭발적인 증가 및 대용량 비디오 트래픽으로 인한 트래픽 폭증 현상에 대한 대처 방안을 마련하는 것이 시급하다. 또한, 7.7 DDoS(Distributed Denial-of-Service), 3.4 DDoS 대란 등의 네트워크 침해 사태에 대한 근본적인 대처 방안을 마련하는 것 역시 매우 중요하다. 이러한 현재 인터넷의 문제점을 해결하기 위하여, 기존 인터넷과의 호환성을 고려하지 않고, 네트워크를 새로이 설계하고자 하는 “미래인터넷” 연구가 시작되었다. 본 고에서는 최근의 미래인터넷 연구 동향을 살펴보고, 특히 보안성을 해결하고자 하는 미래인터넷 보안 기술의 동향을 소개한다.
