Abstract

Digital The I2C (Inter-Integrated Circuit) protocol is widely used in embedded systems for enabling communication between various devices such as sensors, microcontrollers, and other peripherals. However, early implementations of the I2C protocol focused primarily on data transfer efficiency rather than security This project aims to implement a secure data transfer mechanism for the I2C protocol using Verilog, a hardware description language widely used for designing and modelling electronic systems. Our implementation enhances the traditional I2C protocol by integrating security features that protect data from unauthorized access during transmission. By using encryption and authentication techniques, the project ensures that data integrity and confidentiality are maintained throughout the communication process. The Xilinx Vivado Design Suite is utilized for the synthesis, simulation, and testing of the secure I2C protocol. Xilinx software provides a robust environment for designing hardware-based systems, offering features such as timing analysis, design optimization, and resource management. The secure I2C protocol was implemented and simulated using Verilog code within this software, enabling thorough testing and debugging prior to hardware deployment. The hardware component of the project is based on the Zybo Z7 development board. The Zybo Z7 kit provides an ideal platform for prototyping and testing the secure I2C protocol, as it allows for real-time interaction between the FPGA and peripheral devices connected through I2C communication. By running the implemented design on this hardware, we were able to evaluate the real-world performance and security of the system. The results demonstrate that the secure I2C protocol operates efficiently on the Zybo Z7 kit, with minimal impact on system performance. The integration of security features did not introduce significant latency or resource overhead, indicating that secure communication can be achieved without compromising speed or functionality. This successful implementation highlights the feasibility of deploying secure I2C protocols in hardware systems where data protection is a priority.
