QShield Secure File Sharing Service is a quantum-resistant encryption solution designed to protect data against future quantum computing threats. The service utilizes quantum random number generation (QRNG) through the TROPOS system to generate unpredictable encryption keys. The platform provides secure file storage with encrypted data protection and ensures data integrity over extended periods. Files are encrypted using AES-256 encryption with 256-bit key lengths. The service includes automated data deletion mechanisms that securely erase sensitive information after predefined periods. The solution offers on-demand decryption capabilities, allowing authorized users to access protected information when needed. It supports secure web access for enterprise networks, both on-premises and remote locations. The service can be deployed as Encryption as a Service (EaaS) and includes quantum-safe VPN capabilities for data in transit. QShield integrates quantum-generated seeds for enhanced security and provides long-distance data transit protection. The platform is designed for multiple industries including government, defense, banking, finance, healthcare, telecom, data centers, automotive, and enterprise environments. The service aims to protect against information leaking in campus networks with quantum mobility support for WiFi, LiFi, and other wireless technologies.
