• Quantum Key Distribution (QKD)
provides unconditional security by
generating an information theoretically
secure key, for “data in motion”
• Strength of the security is not just in
increasing strength of encryption but in
providing the key securely on either
end of a transaction.
• QKD guarantees quantum
randomness. This property allows us
to enhance security of the “data at
rest”.
• QKD from QNu, can enhance the
security of the healthcare IT
ecosystem by providing a Quantum
secure shield.
• QKD is an insurance against “harvest
now decrypt later”.

QRNG and Entropy as a service
QRNG is a hardware random number generator where generation of
random numbers are based on the properties of quantum mechanics.
The quality of key generation is strongly dependent on entropy. EaaS
provides high entropy random data for use in cryptography.
Entropy is used in
Lottery, gaming, OS scheduling, simulators, AI algorithm.
