By Konstantinos Karagiannis
Quantum computing will bring tumultuous change to the world of information security in the coming decade. As multi-qubit systems use quantum algorithms to slice through even 4096-bit PK encryption in seconds, new Quantum Encryption will be required to ensure data security. Join Konstantinos for a look at real world experiments in Quantum Key Distribution that BT and partners have recently performed that show what the future of encryption will look like. Remember the panic after Heartbleed when SOME passwords needed to be changed? Imagine a day when ALL communications are at risk of eavesdropping via Quantum Computers - a day when only new systems that exploit the weirdness of quantum mechanics can ensure privacy.

Quantum key distribution (QKD) uses quantum mechanics to guarantee secure communication. 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. It is often incorrectly called quantum cryptography, as it is the best-known example of a quantum cryptographic task.
An important and unique property of quantum key distribution is the ability of the two communicating users to detect the presence of any third party trying to gain knowledge of the key. This results from a fundamental aspect of quantum mechanics: the process of measuring a quantum system in general disturbs the system. A third party trying to eavesdrop on the key must in some way measure it, thus introducing detectable anomalies. By using quantum superpositions or quantum entanglement and transmitting information in quantum states, a communication system can be implemented that detects eavesdropping. If the level of eavesdropping is below a certain threshold, a key can be produced that is guaranteed to be secure (i.e. the eavesdropper has no information about it), otherwise no secure key is possible and communication is aborted.
The security of encryption that uses quantum key distribution relies on the foundations of quantum mechanics, in contrast to traditional public key cryptography, which relies on the computational difficulty of certain mathematical functions, and cannot provide any mathematical proof as to the actual complexity of reversing the one-way functions used. QKD has provable security based on information theory, and forward secrecy.
Quantum key distribution is only used to produce and distribute a key, not to transmit any message data. This key can then be used with any chosen encryption algorithm to encrypt (and decrypt) a message, which can then be transmitted over a standard communication channel. The algorithm most commonly associated with QKD is the one-time pad, as it is provably secure when used with a secret, random key. In real-world situations, it is often also used with encryption using symmetric key algorithms like the Advanced Encryption Standard algorithm.

BB84 protocol is a quantum key distribution scheme developed by Charles Bennett and Gilles Brassard in 1984.
It is the first quantum cryptography protocol.
The protocol is provably secure,
relying on the quantum property that information gain is only possible at the expense of disturbing the signal if the two states one is trying to distinguish are not orthogonal (see no-cloning theorem). It is usually explained as a method of securely communicating a private key from one party to another for use in one-time pad encryption.
Alice creates a random bit of 0 or 1 and
then randomly selects one of her two bases (rectilinear or diagonal) to transmit it in.
She then prepares a photon polarization state depending both on the bit value and basis.
So for example a 0 is encoded in the rectilinear basis (+) as a vertical polarization state, and a 1 is encoded in the diagonal basis (x) as a 135° state.
Alice then transmits a single photon in the state specified to Bob, using a quantum channel.
This process is then repeated from the random bit stage,
with Alice recording the state, basis and time of each photon sent.
As Bob does not know the basis the photons were encoded in,
all he can do is to select a basis at random to measure in, either rectilinear or diagonal.
He does this for each photon he receives, recording the time, measurement basis used and measurement result.
After Bob has measured all the photons,
he communicates with Alice over the public classical channel.
Alice broadcasts the basis each photon was sent in,
and Bob the basis each was measured in.
They both discard photon measurements (bits)
where Bob used a different basis,
which is half on average,
leaving half the bits as a shared key.
Quantum key distribution is only used to produce and distribute a key, not to transmit any message data. This key can then be used with the one-time pad cipher with a secret random key.

Lyrics:
Do you say the things you used to?
Do you remind me of who you were?
But I don't really need her
Cus you're here
By my side
Back with me
Ya, I know that I don't want to give you up
I still eat the things I used to
Would you rewind me back to who I was?
It's ok for you to say it's not
What you thought
It would be
Back with me
Ya, I know that I don't want to give you up

Cryptography is the art of secret writing. Cryptography or Encryption is essential for securing data, either in transit or stored on devices. It provides assurance and confidence that communications will not be intercepted and that sensitive information stored on devices can’t be exfiltrated in the event of loss or theft. However, a system is vulnerable to the brute force attack, increased computational power and futuristic technology such as quantum computing. Quantum cryptography is resilient to Quantum Computers and it should be integrated into the present cryptosystems for long-term confidential applications. Quantum key distribution (QKD) and Post quantum cryptography (PQC) are the two ingredients for quantum safe encryption. In this webcast we are going to explore Quantum computing based security in deep to help you understand the future of Security.

keep good habits /
light from a dead star
shines so bright and far
and here we lay
in the glow of decay
lots of things are lame
and get in the way
i don't go bother with them
in a life that's pretend
you can know sohcahtoa
but have no idea
that you'll never really feel
if you don't see too clear
oh no
you're alone
keep good habits
try to be crazy
fuck like rabbits
don't be too lazy
i swim in deep green eyes
it's so hard to stay dry
when i am lost at sea
and there's no map to guide me.
people asking why
i don't give up the good fight
well i won't burn out bitch
cus i'm too young to quit
you can know sohcahtoa
but have no idea
that you'll never really feel
if you don't see too clear
oh no
you're alone
keep good habits
try to be crazy
fuck like rabbits
don't be too lazy

CHORONZON – FIAT NOX
PANICMACHINE 2011.
Don't look too close. In end you'll believe. A king in Yellow, neurotransmitters extend through quantum states, a POMO economy and culture renders all attempts at understanding and manipulation futile. CHORONZON has found you.
Over the years Choronzon have become known for their thick vortex of blackened ritualistic industrial chaos. P. Emerson Williams has shaped this release the way a sculptor creates art by removing any unneeded element. With FIAT NOX CHORONZON scaled back the electronics and loops on to where guitars and vocals carry the pieces, except where cellos take over on one piece. Very stripped down, no fx on the guitars. The results are no less of a demonic vortex for this sharpening of focus.
Lyrically, the album centers around pivotal moments. The moment when an empire is in a free-fall, the point of evocation when the entity is undoubtedly and with fearsome immanence manifest, when one is on the path and there can be no going back. In the Abyss there is no time, nor space. The only way out is through and the only way to emerge is to leave yourself there. The biggest crimes are committed with the help of armies and authorities, so freedom has to be declared by the night.
