Proposed Abstract:

The PRESENT cipher, an ultra-lightweight block cipher, has been designed specifically for environments where resource constraints are a critical factor, such as RFID tags, sensor networks, and various IoT devices. Its compact design, featuring a 64-bit block size, 80-bit key, and 31 rounds, makes it particularly suitable for applications requiring minimal hardware resources, low power consumption, and moderate security. Unlike more robust ciphers like AES, which demand significant computational and memory resources, PRESENT strikes an optimal balance between efficiency and security for constrained devices. This paper explores the practical applications of the PRESENT cipher in secure communication protocols, device authentication, and data encryption in low-power systems. By synthesizing 16-bit, 32-bit, and 64-bit implementations on a Xilinx Virtex-5 FPGA, we demonstrate the cipher’s adaptability across a range of use cases, analyzing key performance metrics such as area, delay, and power consumption. Our findings indicate that PRESENT is highly effective in scenarios where traditional cryptographic solutions are too resource-intensive, offering a viable alternative for securing data in pervasive computing environments. PRESENT’s applications extend to securing communication in embedded systems, protecting sensitive information in contactless payment systems, and enabling secure data transmission in wireless sensor networks. The cipher’s lightweight design ensures that it can be implemented in devices with limited processing capabilities, making it an ideal choice for modern IoT applications. However, the trade-off between security and efficiency must be carefully considered. While PRESENT is suitable for applications with moderate security requirements, it may not provide the level of protection needed for high-security environments.
