Implementation of lightweight cryptographic algorithms in FPGA

With the advancements in technology the needs of security systems to protect data are becoming crucial. The shift from high end devices such as desktop computers, servers and laptops to small constrained devices brings a wide range of new security challenges. The major concern of such devices is the storage, access and transmission of critical data. Lightweight cryptography refers to the branch of cryptography for developing cryptographic algorithms and its implementation in resource constrained devices like smart cards, RFID tags ,wireless sensors, Internet of Things(IoT) etc. In this paper the implementation of 64 bit plaintext input cryptographic algorithms in FPGA has been proposed.
