Featured Projects
Quantum Secure Email System (QSES)
A hybrid email security system encrypting data with AES-256 while securely generating and exchanging decryption keys via Quantum Key Distribution (QKD). Combines classical encryption with quantum communication, leveraging quantum physics to detect eavesdropping in real time — keys cannot be intercepted without alerting both parties.
