Abstract

Internet of Things (IoT) connects devices with various platforms, computing power, and functions. Due to the diversity of networks and the ubiquity of IoT devices, demands for security and privacy are increasing. Therefore, cryptographic mechanisms must be strong enough to meet these increased requirements, while at the same time effective enough to be implemented in devices with long-range specifications. In this paper, we present the performance and memory limitations of modern cryptographic primitives and schemes for different types of devices that can be used in IoT. In addition, detailed performance evaluation of the performance of the most commonly used encryption algorithms in low-spec devices frequently used in IoT networks is performed. To provide data protection, the binary ring uses encryption asymmetric fully homomorphic encryption and symmetric encryption AES 128-bit. As a result of the experiment, it can be seen that the IoT device had sufficient performance to implement a symmetric encryption, but the performance deteriorated in the asymmetric encryption implementation.

사물인터넷(IoT)은 다양한 플랫폼, 컴퓨팅 성능, 기능을 가지는 장치를 연결한다. 네트워크의 다양성과 IoT 장치의 편재로 인해 보안 및 개인 정보 보호에 대한 요구가 증가하고 있다. 따라서 암호화 메커니즘은 이러한 증가된 요구 사항을 충족할 만큼 충분히 강력해야 하고 동시에 저 사양의 장치에 구현될 수 있을 만큼 충분히 효과적이어야 한다. 논문에서는 IoT에서 사용할 수 있는 다양한 유형의 장치에 대한 최신 암호화 기본 요소 및 체계의 성능 및 메모리 제한 사항을 제시한다. 또한, IoT 네트워크에 자주 사용되는 저 사양의 장치에서 가장 일반적으로 사용되는 암호화 알고리즘의 성능에 대한 자세한 성능 평가를 수행한다. 데이터 보호 기능을 제공하기 위해 바이너리 링에서 암호화 비대칭 완전 동형 암호화와 대칭 암호화 AES 128비트를 사용했다. 실험 결과 IoT 장치는 대칭 암호를 구현하는데 충분한 성능을 가지고 있었으나 비대칭 암호 구현에서는 성능이 저하되는 것을 알 수 있다.
