초록
임베디드 마이크로 프로세서는 기존의 컴퓨터에 비해 제한적인 컴퓨팅 파워로 인해 간단한 연산과 작업의 수행에보다 적합한 기기로 간주되어 왔다. 하지만 최근 들어 임베디드 마이크로 프로세서의 발전으로 인해 다양한 서비스를제공하는 것이 가능해 졌다. 이와 더불어 안전하고 신뢰성 높은 서비스의 제공을 위해 임베디드 장비 상에서의 보안의중요성이 갈수록 높아지고 있다. 현재 임베디드 장비 상에서의 다양한 암호화 구현 기법들이 제시되고 있다. 본 논문에서는 대표적인 8-, 16-, 32-비트 임베디드 장비인 AVR, MSP, 그리고 ARM 상에서 진행된 다양한 보안 구현 결과들을 비교 분석한다. 이는 추후 연구자들의 임베디드 장비 상에서의 암호 구현 연구에 많은 도움이 될 것이다.
Abstract
Traditionally embedded microprocessors is considered as a device for low- and simple-computations because of its limited computing power and constrained resources. However high-end embedded devices have been developed and many applications are getting feasible in the embedded devices. To provide secure and robust service environments, security on embedded devices are in order. Recently many research results on embedded devices have been proposed. In this paper, we explore various cryptography implementation results on representative 8-, 16- and 32-bit embedded processors including AVR, MSP and ARM. This report would be helpful for following researchers who are interested in cryptography implementation techniques on resource constrained devices.
