초록

수중 통신 상에서 가장 중요한 요소는 한정된 전원을 보다 효율적으로 소모하여 운영 가능 시간을 최대화하는데 있다. 보다 효율적인 전압 소모를 위해 적용 가능한 기법으로는 동적 전압 스케일 기법이 있다. 해당 기법은 평상시에는 낮은 주파수로 동작하여 대기 전력을 최소화하며 복잡한 연산을 수행하는 경우에는 빠른 주파수로 계산함으로써 전체 소모되는 전력량을 줄인다. 복잡한 암호화 연산의 경우 빠른 주파수로 연산을 하는 것이 보다 효율적이다. 본 논문에서는 다양한 센서 상에서의 암호화 기법에 동적 전압 스케일 기법을 적용한 결과를 보여 줌으로써 수중 통신 상에서 적합한 저전력 암호화 방안에 대해 살펴본다.

Maximizing the operating time by reducing the power consumption is important factor to operate sensor network under water networks. For efficient power consumption, dynamic voltage scaling method is available. This method operates low frequency when there is no workload. In case of abundant workload, high frequency operation completes hard work within short time, reducing power consumption. For this reason, complex cryptography should be computed in high frequency. In this paper, we apply dynamic voltage scaling method to cryptography and show performance evaluation. With this result, we can reduce power consumption for cryptography in under water communication.
