The problem QuantumCure solves

1. Eavesdropping: The use of encryption, particularly end-to-end encryption, prevents unauthorized parties from listening in on the communication.

2. Man-in-the-Middle Attacks: By employing strong authentication and secure key exchange mechanisms, the solution mitigates the risk of attackers intercepting and altering the communication.

3. Data Tampering: Encryption ensures that even if data is intercepted, it cannot be easily modified without detection.
   Secure Key Management:

4. The use of PKI and Diffie-Hellman key exchange ensures secure key negotiation and management.
   Usability:

By seamlessly integrating encryption into the communication process and ensuring minimal impact on performance, the solution maintains user-friendliness.
This prototype solution addresses security concerns while considering usability and efficiency, providing a robust and effective means of securing sensitive data transmission.

Challenges we ran into

One significant challenge encountered during the development was ensuring backward compatibility with older systems while implementing the latest security protocols. This required careful consideration of protocol negotiation and fallback mechanisms to maintain secure communication across different platforms.

To overcome this challenge, we conducted extensive testing with diverse system configurations, identifying compatibility issues early in the development cycle. Regular updates and collaboration with security experts were crucial to addressing these issues promptly and ensuring a robust and interoperable solution.
