Quantum Key Encryption System with Automatic Data Termination

The patent introduces a quantum key distribution system as an intermediary mechanism that generates and distributes encryption keys through quantum channels. This intermediary quantum key distribution layer allows parties to share keys securely without directly transmitting classical encryption keys, thereby eliminating the vulnerability to key interception while maintaining the ability to encrypt and decrypt data

The patent replaces the classical mechanical key sharing system with a quantum mechanical system. Instead of transmitting classical encryption keys through conventional channels, the system uses quantum states (photons) to encode and transmit key information, leveraging quantum mechanical properties such as superposition and entanglement to achieve secure key distribution that cannot be intercepted without detection

The patent implements dynamic data access control where the accessibility of decrypted data is not static but changes over time. The system automatically manages data lifecycle including generation, distribution, usage, and destruction of decrypted data, ensuring that data remains accessible only during the required period and is automatically destroyed afterward, thereby maintaining ease of operation during the valid period while eliminating long-term security vulnerabilities

The patent implements automatic discarding of decrypted data after its useful purpose is fulfilled. The system includes mechanisms to automatically destroy decrypted data after a predetermined period or after the completion of the intended operation, preventing unauthorized access while maintaining data accessibility during the required time frame. This includes secure deletion protocols that ensure data cannot be recovered after destruction
