A New Compact-Data Encryption Standard (NC-DES) Algorithm Security and Privacy in Smart City

A smart city is an innovative, urban, organized, and sustainable city. It mainly depends on the Internet of Things (IoT) technology which improves the excellence of living, safety, the operational efficiency of urban services, decision-making, government services, and social well-being of its people. Smart city means dealing smart in education, government, mobility, households, and e-health. IoT enables all smart devices to connect through the Internet, like sensors, detectors, actuators, wearable’s, mobile phones, watches, and smoke detectors. The rapid increase of Internet of Things in most smart city applications defines new security hazards that threaten the confidentiality and safety of end devices. Therefore, it is significant to improve smart services and the information protection and privacy process. The IoT devices need wireless sensor links and Radio Frequency Identification (RFID) to benefit from IoT. These resource-limited require common authentication between the devices through the association of a novel device, where authentication and encryption of the data to be sent. This paper has three contributions. First, surveying the fundamental smart city privacy problems. Second, the paper proposes a firm, trivial, and energy-efficient security solution for IoT systems which is called; New Compact-Data Encryption Standard (NC-DES). Finally, a case study of the healthcare framework is taken as an example of IoT applications to provide secure transfer of the measured parameters. The proposed system proved that the IoT devices had been secured without wasting their limited resources.
