The Post-quantum
Apocalypse

This incredible technology
will help find a cure for
cancer--and, unfortunately,
will hack all any secure
chat conversations in a seconds.
What may be advantages today will become disadvantages tomorrow
Vernam IM - the most secure chat app
There are many popular secure messaging apps
on the market now. Some offer great safety features
for users, except for major one: None of them
are Quantum-resistant at all. That means that when
the New Quantum Computing Era comes, their
current security advantages will immediately
become their disadvantages.

Have a look here. As you can see, no one can be 100% sure that this security and privacy is real.

Here is a slide from the NIST presentation on
04-11-2018. We can see that RSA - 2048 has been hacked already (Telegram, Skype). Furthermore, Elliptic-Curve cryptography (Curve 25519, for example, is used in Messenger,
Signal, WhatsApp, Viber, Threema, Wire and many more) is also based on similar mathematical methods, like RSA, and is used in almost every popular secret messenger.

Based on these facts, we can conclude that all existing messengers that are now
on the market will be hacked (it's only a matter of time) because they use similar
methods of protection.

But what about in everyday life?

A huge number of users trust (right now) their privacy and security to systems that are no longer safe.

For example, how does a user know that their favorite safe messenger app has been hacked?
The fact is, they will never know, all the while continuing to trust the security of the system.
Even if a user has not been compromised now, it's inevitable that they will be in the future.

As it stands, all current systems will be compromised thanks to the approaching Quantum Computing Era. As soon as quantum computers reach the mainstream, even the best
security system will become meaningless.

No one is certain when this revolution will arrive - a few years from now, or perhaps much
sooner - but when the day comes, people will be in a panic looking for replacement services
that are secured against quantum computing.

Quantum computing is already online

Today, anyone can conduct cloud computing using IBM's quantum computer online. However, what is unsettling about this is that the user doesn't have any way of knowing if his/her correspondence was hacked by some curious schoolboy that used this service. All this time, the user will trust his/her own security to systems that have already lost all their virtues, which makes one wonder why they still exist.

SCHNEIER ON SECURITY
Several groups are working on designing and building
a quantum computer, which is fundamentally
different from a classical computer.

If one were built - and we're talking science fiction
here - then it could factor numbers and solve
discrete-logarithm problems very quickly.

In other words, it could break all of our commonly
used public-key algorithms.

NIST POST QUANTUM PROJECT
In recent years, there has been a substantial amount
of research on quantum computers – machines
that exploit quantum mechanical phenomena
to solve mathematical problems that are difficult
or intractable for conventional computers.

If large-scale quantum computers are ever built, they
will be able to break many of the public-key
cryptosystems currently in use.

This would seriously compromise the confidentiality
and integrity of digital communications
on the Internet and elsewhere.

NSA PREPS QUANTUM - RESISTANT ALGORITHMS TO HEAD OFF CRYPTO - APOCALYPSE
The National Security Agency is advising US agencies
and businesses to prepare for a time in the not-too-distant future when the cryptography protecting virtually all
e-mail, medical and financial records, and online transactions is rendered obsolete by quantum computing.

Quantum computers have capabilities that can lay to ruin all of the public-key cryptographic systems
currently in use.

The quantum computing apocalypse is imminent

The National Security Agency, too, has sounded the alarm on the risks to cybersecurity in the quantum computing age. The NSA's "Commercial National Security Algorithm Suite and Quantum Computing FAQ" says that "many experts predict a quantum computer capable of effectively breaking public key cryptography" within
"a few decades," and that the time to come up with solutions is now.

According to many experts, the NSA is far too conservative in its prediction; many experts believe that the timeline is more like a decade to a decade and a half,
while others believe that it could happen even sooner.
