초록
최근 드론으로 수집되는 데이터의 양이 급증함에 따라, 데이터를 안전하고 효율적으로 저장 및 처리할 수있는 클라우드 컴퓨팅 기술의 지원이 필요하다. 하지만, 드론에서 통신하는 데이터를 공격자로 인해 탈취되거나, 유출, 위·변조 등 다양한 보안 취약점이 발생할 수 있다. 따라서 드론으로부터 수집되어 전송되는 데이터에보안 기술이 필요하다. 다양한 보안 기술 중 속성기반암호인 KP-ABE 기법은 데이터 암호화와 사용자 접근 제어, 두 가지 특성을 만족시키는 보안 기술이다. 본 논문은 KP-ABE 기법을 연구하고, 이를 드론 환경에 활용하여 안전한 데이터 접근 제어 기법을 제안하고자 한다. 본 제안 기법은 드론 환경에서 통신되는 데이터의 기밀성과 무결성 및 안전한 접근 제어와 가용성이 제공된다. 그리고 KP-ABE 기법에서 제공해야 할 요구사항 중빠른 암호문 탐색 및 일정 크기 암호문 출력을 제공한다.
Abstract
Recently, as the amount of data collected by drones has rapidly increased, it is necessary to support cloud computing technology that can securely and efficiently store and process data. However, various security threats such as stealing, leaking, or tampering with data communicated by drones can occur due to attackers. Therefore, there is a need for security technology to provide secure communication of data collected from drones. Among various security technologies, the KP-ABE scheme, which is attribute-based encryption, is a security technology that satisfies two characteristics: data encryption and user access control. This paper researched the KP-ABE scheme and proposed a secure data access control scheme to the drone environment. This proposed scheme provides confidentiality and integrity of data communicated in a drone environment and secure access control and availability. In addition, it provides a fast ciphertext search and constant size ciphertext among the requirements to be provided in the KP-ABE scheme.
