Cybersecurity Encryption



PQC refers to cryptographic algorithms (usually public-key algorithms) that are thought to be secure against a cryptanalytic attack by a quantum computer. The problem with currently popular algorithms is that their security relies on one of three hard mathematical problems: the integer factorization problem, the discrete logarithm problem, or the elliptic-curve discrete logarithm problem. All of these problems can be easily solved on a sufficiently powerful quantum computer running Shor’s algorithm.

It is intended that the new public-key cryptography standards (NIST) will specify one or more additional unclassified, publicly disclosed digital signature, public-key encryption, and key-establishment algorithms that are available worldwide, and are capable of protecting sensitive government information well into the foreseeable future, including after the advent of quantum computers.


QKD is a secure communication method which implements a cryptographic protocol involving components of quantum mechanics. It enables two parties to produce a shared random secret key known only to them, which can then be used to encrypt and decrypt messages.
QKD works by transmitting light particles through fibre optic cables. Using the properties of quantum mechanics, if there is a disturbance such as eavesdropping detected during transit, the key adapts and actually changes. In fact, the attacker can’t hack the transmission, and actually impossible to snoop on the network.
The problem nowadays and significant challenges include the limited distance a quantum key can travel, transmission only point-to-point, poor interoperability with equipment and systems from various suppliers/vendors, as well as costly dedicated fibre is necessary.
These QKD limitations likely need several more years to address and overcome — design stage, tests in a lab, then deployment in a real-world and commercial setting.
Despite the above QKD limitations, unlike other existing security solutions, QKD is the only secure from all future advances in mathematics and computing, including the usage of a quantum computer.
Nowadays, QKD is used to distribute the secret digital keys important for protecting highly sensitive data critical to many industries. It protects data in the defence, finance, utilities, and health sectors as well as the critical infrastructure that underpins smart cities and smart energy grid.


The Range of Data-in-Transit Security is wide enough, but we can guide you and provide consultancy, especially for quantum-safe solutions that could be applied.
Quantum-safe VPN could replace current public key encryption methods to establish encryption keys using Post Quantum Cryptography (PQC).
The solution as a quantum-safe VPN supports quantum keys from any key-generating source or delivery method (QKD, PQC, QRNG, or a combination).
It could be applied across any network media with no distance limitations and supports all PQC candidate algorithms.
Thus customers can change PQC algorithms without disturbing their networks.
The following options are available with a special product (SP):
– QKD paired with SP fiber;
– Quantum entropy paired with SP over TCP/IP;
– Quantum-resistant encryption with SP over TCP/IP;
– Traditional encryption with SP over TCP/IP;
