지능형 인공지능 시스템을 위한 동적 부분 업데이트 기술 기반 고속 간헐적 임베디드 소프트웨어 관리

초록

As embedded systems evolve, embedded system updates becomes more important. In particular, over-the-air(OTA) technology is widely used via wireless for updating automotive control algorithm. Applying OTA technology for updating mission-critical control software has several problems due to characteristics of wireless communication. First, the on-chip software update on driving automobiles may be paused during the update due to various intervention or disconnection of network. Second, the transmission data may be changed due to poor update channel status. Third, the update file may be eavesdropped. In this paper, we propose a fast and secure update protocol that is intermittent and can cope with channel errors. In addition, partial update and runtime update is possible by designed to be applied to systems using dynamic library. The experimental results for dynamically linked software show our approach is effective for seamless software update under intermittent environment.
