Abstract:
This paper examines a method for establishing secure communication channels on online platforms using post-quantum cryptography. It is shown that quantum attacks on communication channels can compromise the security of banking data, critical information infrastructure, and state secrets. Therefore, when establishing a communication channel, the protection of registration data exchange should be built using post-quantum cryptography. The paper proposes using the CRYSTALS cryptosystem in combination with Shamir’s secret sharing scheme during the registration phase. The latter is used to securely distribute the “seed,” a unique random sequence from which cryptographic keys are generated. Dividing the “seed” among multiple nodes eliminates a single point of compromise and reduces the risk of internal threats, including abuse by administrators. The proposed method allows users to securely restore access on additional devices. The platform for building communication channels is based on a federated architecture that ensures secure messaging between branches while maintaining core data within trusted networks. Client applications verify the integrity of server responses and the application itself, preventing man-in-the-middle attacks. The growing number of online communication platforms requires the implementation of reliable mechanisms for secure user registration, especially in environments handling sensitive information. The proposed solution provides a quantum-resistant and fault-tolerant method for establishing secure communication channels, guaranteeing the confidentiality, verifiability, and recoverability of user registrations across devices.
