Abstract

A WAVE(Wireless Access for Vehicular Environment) system is a vehicle communication technology. The system provides the services to prevent vehicle accidents that might occur during driving. Also, it is used to provide various services such as monitoring vehicle management and system failure. However, the scrambler bit operation of WAVE system becomes less efficient in the organizations of software and hardware design because the parallel processing is impossible. Although scrambler algorithm proposed in this paper has different processing speed depending on input data 8 bit, 16 bit, 32 bit, and 64 bit. it improves the processing speed of the operation because it can make parallel processing possible depending on the input unit.

WAVE(Wireless Access for Vehicular Environment) 시스템은 차량용 통신 기술로서, 차량 운전 중 발생 가능한 사고들을 미연에 방지하기 위한 서비스와 차량기능 관리, 시스템 장애를 모니터링하는 각종 서비스를 제공하기 위해 사용된다. 그러나 WAVE 시스템의 스크램블러 비트 연산은 병렬 처리가 불가능하므로 소프트웨어나 하드웨어 설계의 효율성이 떨어지게 된다. 본 논문에서는 스크램블러의 비트 연산 과정으로 행렬 테이블을 구성하는 알고리즘과 입력 데이터와 행렬 테이블을 병렬 연산하는 알고리즘을 제안한다. 본 논문에서 제안한 스크램블러 알고리즘은 입력 데이터의 입력 단위가 8비트, 16비트, 32비트, 64비트냐에 따라 처리 속도가 다르지만 입력 단위에 따라 병렬 처리가 가능하므로 WAVE 시스템의 처리 속도를 더욱 향상시킨다.
