Abstract

This paper proposes the hybrid crypto-system for fast video data encryption of UAV(Unmanned Aerial Vehicle) under the LTE(Long-Term Evolution) wireless communication environment. This hybrid crypto-system is consisted of ECC(Elliptic Curve Cryptography) public key algorithm and LEA(Light-weight Encryption Algorithm) symmetric key algorithm. ECC is a faster public key algorithm with the same security strength than RSA(Rivest Shamir Adleman), and Korean standard LEA with the same key size is also a faster symmetric key algorithm than AES(Advances Encryption Standard). We have implemented this hybrid crypto-system using OpenSSL, OpenCV and Socket programs under the Swarm 8-UAV. We have shown the efficient adaptability of this hybrid crypto-system for the real-time swarm UAV through the experiments under the LTE communication environment.

본 논문은 LTE 통신망 환경에서 군집 UAV의 비디오 영상 데이터를 고속으로 암호화하기 위한 하이브리드 암호시스템을 제안한다. 이 암호시스템은 ECC 공개키 알고리즘과 LEA 대칭키 알고리즘으로 구성된다. ECC는 RSA보다 빠르면서 동일한 보안성을 가지며, LEA는 동일한 키로 AES보다 빠른 국내 표준 알고리즘이다. 본 논문은 OpenSSL과 OpenCV를 활용하여 Socket 프로그램으로 8개의 군집 UAV 환경에서 하이브리드 암호시스템을 구성하여 구현하였다. 실험을 통하여 본 하이브리드 암호시스템이 실시간 환경에서 효율적으로 적용이 가능함을 보인다.
