FAQs For Key Takeaways
Demystifying quantum cryptography and its real-world impact.
Quantum security encompasses principles and practices to protect data and communication against threats from quantum computing, which could compromise current cryptographic algorithms. Quantum cryptography uses quantum mechanics principles, like superposition and entanglement, to encrypt and decrypt data, offering potentially unbreakable security.
Quantum cryptography ensures secure communication between two parties, often called Alice and Bob, using Quantum Key Distribution (QKD). QKD allows them to generate a shared, random secret key for encrypting and decrypting messages. A key principle is that any measurement of a quantum system alters its state, so if an eavesdropper (Eve) tries to intercept the communication, her presence will be detected by the changes in the system’s state. This fundamental property of quantum mechanics ensures the security of QKD.
Current cybersecurity relies heavily on asymmetric cryptography for authentication and key exchange. Quantum computers threaten these methods because they can potentially break algorithms like RSA and Elliptic Curve Cryptography. Quantum algorithms, such as Shor’s algorithm, can factorize large numbers much faster than classical algorithms, risking the security of digital communications.
TQSN (Terra Quantum's patented protocol) is quantum-safe because it resists attacks from quantum computers and relies on fundamental laws of quantum physics. It does not depend on computational assumptions, making it immune to higher computational powers. The protocol challenges eavesdroppers to distinguish between non-orthogonal quantum states, which is impossible without errors due to quantum laws. The security is quantified using the Holevo theorem and is theoretically proven based on the second law of thermodynamics and precise loss control. Unlike other protocols, such as BB84, the TQ protocol ensures everlasting security even against future technologies or attacks.
Current challenges of quantum cryptography include high initial costs, complex technical requirements, maintaining quantum states over distances, and ensuring stable environmental conditions. However, the future is promising with ongoing advancements such as transitioning from dark fiber to lit fiber networks, which reduces costs and expands reach by using existing telecommunications infrastructure for Quantum Key Distribution (QKD). Additionally, progress is being made towards dynamic point-to-multipoint configurations, enhancing network coverage and allowing more users to connect securely.
