The objective of this project is to design and implement a Secure Email Encryption System using Public Key Infrastructure (PKI) that ensures confidentiality, authentication, and data integrity. The system will demonstrate practical cryptographic techniques suitable for BCA and MCA students, integrating security concepts with real-world application development.
Study fundamental concepts of cryptography, including symmetric and asymmetric encryption.
Understand the working of Public Key Infrastructure (PKI) and digital certificates.
Analyze encryption algorithms such as RSA and hashing algorithms like SHA.
Design system architecture for a secure email communication model.
Develop a user registration module with public–private key pair generation.
Implement public key storage and certificate verification mechanisms.
Create an email composition module with encryption using the recipient’s public key.
Implement decryption functionality using the receiver’s private key.
Integrate digital signature functionality for authentication and integrity.
Develop database structures to store user credentials and keys securely.
Apply secure coding practices to prevent vulnerabilities such as key exposure.
Test the system for confidentiality, integrity, and authentication features.
Perform unit and integration testing for encryption/decryption modules.
Prepare system documentation including ER diagrams, DFDs, and flowcharts.
Compare the developed system with existing secure email standards.
(For MCA students) Enhance the project with certificate authority simulation, revocation lists, and role-based access control.
Deploy the application on a local server or cloud-based environment for demonstration.
Prepare project report and presentation explaining technical implementation and security analysis.
