The objective of this project is to design and implement a Secure IoT Device Authentication System using cryptographic techniques to ensure secure communication between devices and servers. The system focuses on device identity verification, encrypted communication, and protection against unauthorized access and spoofing attacks.
Study IoT architecture and common security challenges in connected devices.
Analyze cryptographic techniques such as symmetric encryption, asymmetric encryption, hashing, and digital signatures.
Prepare Software Requirement Specification (SRS) and system security design documentation.
Design system architecture including IoT device simulation, authentication server, and secure communication channel.
Create database schema for device registration, public keys, authentication tokens, and activity logs.
Implement device registration process with unique device ID generation.
Develop authentication mechanism using cryptographic key exchange (e.g., RSA/AES simulation).
Implement encrypted communication between IoT devices and the central server.
Integrate token-based session validation for authenticated devices.
Apply message integrity checks using hashing techniques.
Simulate detection of unauthorized devices or replay attacks.
Maintain logs of device authentication attempts and connection history.
Develop dashboard for monitoring connected devices and authentication status.
Perform security testing including encryption validation and attack simulation.
Prepare documentation including ER diagrams, architecture diagrams, cryptographic workflow, and test cases.
Deploy the system locally for demonstration and performance evaluation.
