Internet of Things (IoT) systems are slowly but steadily becoming part of different aspects of our lives, with their applications ranging from smart homes, to wearable devices, to healthcare, etc. Traditional cryptographic schemes might not be suitable to be implemented on resource limited IoT devices. The decision to utilize a certain cryptographic algorithm, is mainly based on a tradeoff between security and performance, i.e. power consumption. A benchmark of these different cryptographic algorithms on IoT platforms is a must for security architects while designing their protocols and schemes. This paper presents a benchmark of the most known cryptographic algorithms on the Raspberry Pi platform, with a comparison with Arduino benchmark results provided in the literature.
