Lightweight block cipher on VHDL

Internet of Things (IoT) will change how we interact with our physical world. It will enable total sensing and controlling of most of the things around us. However, the practical acceptance of IoT from the market determine by the level of confidence perceived by the user. This is why IoT security is the main issues or concern of real IoT deployment. IoT security need light encryption engine that makes the encryption process very fast and efficient. Here we simulate the implementation of lightweight block cipher on VHDL that can be further realized on real hardware in the form of ASIC or FPGA chips. The results are compared from three points of views, security, physical size on hardware. Achieving the balance between these 3 areas is the key success of efficient cryptography implementation for IoT systems.
