The Internet of Things (IoT) plays an essential role in connecting a small number of billion devices with people for diverse applications. The security and privacy with authentication are challenging work for IoT devices. A lightweight block cipher is designed and modeled with IoT security for real-time scenarios to overcome the above challenges. The light-weight PRESENT module with the integration of encryption (E)-decryption (D) is modeled and implemented on FPGA. The PRESENT module has 64-bit data input with 80/128/256-bit symmetric keys for IoT security. The PRESENT module performs16/32/64 round operations for state register and key updation. The design mainly uses Substitution-permutation (SP) network for state updation. The permutation layer is used to create more diffusion and confusion in the state for unauthorized access. The results and analysis of the PRESENT-80/128/256 are designed using Verilog-HDL with Xilinx Environment and implemented on Artix-7 FPGA. The PRESENT-80/128/256 module is compared with similar recent works with performance improvements. Similarly, the proposed work is compared with different light-weight algorithms with improvements for better security in IoT devices. The proposed PRESENT-256 module with 64-rounds on Artix-7 FPGA utilizes less than 2% Chip area (Slices and LUTs), works at 412.4 MHz frequency, and consumes 192 mW total power and 0.58 Mbps/slice of hardware efficiency.

In this paper, high-throughput and flexible hardware implementations of the SIMON and SPECK lightweight block ciphers are presented. The most complex block in the SPECK algorithm is addition modulo 2 n , where n is word size (half of the input data). In the proposed structure of modular adder, we used the Sklansky adder, which is an efficient parallel prefix adder with low critical path delay and suitable hardware resources. In the SIMON block cipher, to reduce critical path delay, we use a tree structure for implementation of XOR operations.In addition, we proposed flexible structures that can perform various configurations of the SIMON and SPECK ciphers to support variable key sizes (128, 144, 192, and 256 bits) and block sizes (64, 96, and 128 bits). Therefore, the flexible architectures provide versatile implementations with adaptive security level and the ability of encryption of longer messages based on variable key size and variable block size. Implementation results of the proposed structures in 180 nm CMOS technology for different key and block sizes are achieved. The results show that the proposed structures have better critical path delay compared with other's related works. KEYWORDS ASIC, high throughput, lightweight, SIMON block cipher, SPECK block cipher INTRODUCTIONLightweight cryptography has been an important area of cryptographic research in recent years. Different lightweight block ciphers with various design strategies have been presented. 1-3 The advanced encryption standard (AES) is one of the most important and applicable block ciphers in hardware and software. 4 For low-resource devices, the AES is a too expensive block cipher. Therefore, many lightweight block ciphers have been proposed to reduce the costs of hardware consumption than that of AES. Lightweight block cipher algorithms play an important role in the security for resource-constrained devices, such as radio frequency identification (RFID) tags, smart cards, and wireless sensor network (WSN) nodes. SIMON and SPECK 5,6 are lightweight block cipher families with 32 to 128 bits block size and 64 to 256 bits key length, which are suitable for lightweight hardware implementation such as embedded CPUs that are used in the low-area cryptographic application systems. These block ciphers were developed by the National Security Agency (NSA) 5,6 to provide flexibility and security in lightweight applications. These ciphers have been submitted to the International Organization for Standardization (ISO) for inclusion in the ISO 29192-2 standard. The number of rounds in SIMON cipher ranges from 32 rounds to 72 rounds. This cipher has a simple structure based on bit-wise XOR, bit-wise AND, and rotation operations. Also, variants of SPECK block cipher exist for different parameters of key size, block size, 1254
