For that matter, it is important to study the smallest available device in an IoT platform. It is therefore important to design algorithms that are power efficient for IoT devices. This means that it is a technology with the potential to degrade the country’s power within the next fifteen years. The National Intelligence Council (NIC) of the United States in a 2008 report listed IoT as one of the disruptive civil technologies. Many consumers would rather choose an inexpensive insecure device over an expensive secure device for the fact that they are unaware of the cost incurred to them when these devices are hacked. This problem could simply be solved if consumers were willing to pay more for secured devices. IoT devices are usually constrained in terms of hardware area, memory capacity, and processing power making it difficult to implement standard cryptographic protocols to safeguard sensitive data. The Ericsson report also states that 20% of IoT devices are connected over unlicensed radios such as ZigBee, Wi-Fi, and Bluetooth.
IoT devices generally consist of connected meters, wearables, consumer electronics, and connected vehicles. The devices in the P2P networks are always connected and constantly transmitting and receiving data. The IoT platform is made up of low-cost sensing and data collecting devices connected over P2P networks. The design is implemented using Verilog HDL and the 130 nm CMOS cell library is used for synthesis, which results in 33 k gate equivalents at a maximum clock frequency of 50 MHz.Īn Ericsson report in 2016 forecasts that by the year 2022, there will be around 29 billion connected devices out of which peer-to-peer (P2P) networked IoT devices will take up about 62% of all the connected devices.
The lightweight cryptographic SoC is tested by designing a desktop software application to serve as an interface to the hardware. The hardware architectures use the concept of resource sharing to minimize the hardware area. This study implements a System-on-Chip (SoC) based lightweight cryptographic core that consists of two encryption protocols, four authentication protocols, and a key generation/exchange protocol for ultra-low-cost devices. The devices are usually insecure because implementing standard cryptographic algorithms requires the use of a large hardware footprint which leads to an increase in the prices of devices. These devices are usually limited in terms of hardware footprint, memory capacity, and processing power. The backbone of the Internet of things (IoT) platform consists of tiny low-cost devices that are continuously exchanging data.
