Quantum Cybersecurity
Quantum Authentication Protocol with Zero-Knowledge Proof.
Using pre-shared symmetric keys, QAP-0 enables authentication between communicating parties without revealing all or part of the keys to third parties , while avoiding complex calculations.
The security of QAP-0 is guaranteed by the properties of quantum entanglement and the Heisenberg uncertainty principle.
Quantum Authentication Protocol with Unclonable Physical Functions
QAP-PUF provides a method to verify the integrity of devices and authenticate parties in a communication.
By incorporating photonic physically unclonable functions (PUFs) into measurement devices like fingerprints, communicating nodes can verify each other's identities without the need for a trusted third party or pre-key distribution .
Security is guaranteed by the impossibility of cloning PUFs, as well as by the properties of quantum superposition and quantum entanglement. (patent pending)
High-Dimensional Quantum Key Exchange Protocol
QKEP-9 is an entanglement-based quantum key exchange method, where quantum keys are high-dimensional, operate in the telecommunication band , are suitable for low-photon environments, and are adaptable to current classical networks.
QKEP-9 does not require quantum error correction or third-party key management .
Thanks to the use of quantum frequency conversion, QKEP-9 quantum systems can operate at room temperature, be lightweight and compact .
Encryption
Quantum computers will defeat current cryptographic algorithms and will be able to decrypt data while it is being transmitted.
Authentication
Quantum computers will bypass authentication algorithms, making data transmission vulnerable to interception or misuse, or allowing malicious actors to penetrate the communication chain.
Certificates and digital signatures
An adversary with access to a quantum computer can easily forge digital signatures and generate fake certificates.
Cryptographic hash functions
Cryptographic hash functions are frequently used to secure communications. However, quantum computers will be able to break them using fast search algorithms.
Entropy of encryption keys
A vital component of all cryptographic algorithms is random numbers. Random number generators are used to produce encryption keys. Increasing randomness, or entropy, is essential for the future of secure communications.
Privacy-preserving computing
Security threats posed by quantum computers' ability to break both encryption and authentication will undermine the foundations upon which privacy-preserving computing systems are based.
