Quantum Cryptography is not fear mongering - it is inevitable!

Hi All

 

A great piece from this author: 

 

"He concludes that ".... while quantum computing poses significant threats to many current cryptographic standards, research and development into quantum-resistant algorithms show promise in safeguarding our digital information in the quantum age. However, the transition to post-quantum cryptography will require considerable time and effort, underlining the urgency to prepare for the post-quantum world now.
Many organisations have not even started to examine the time and effort that will be required to migrate to post-quantum cryptography. What are you waiting for? And no, its not fear mongering. To quote Agent Smith in the Matrix while he is holding Neo on the subway track, waiting for the train to arrive... "You hear that, Mr. Anderson? That is the sound of inevitability!"

Serious question.  Do you feel that the migration to Post-Quantum will be notably different than the migration from SSL to TLS?

 

My instinct is that if we keep the focus on upgrading/eliminating anything that is out-of-vendor-support, and maintaining a routine patch-cadence for the rest, most organizations will be in about as good a shape as they can/need be.

 

Am I missing anything "big"?

Hi @denbesten 

 

Yes, I do, unfortunately, if I may - it is not just a question of migrating to a new cryptographic algorithm i.e. SSLv3 to TLSv1.2 - knowing the payments industry too six years to actually agree, argue and then did something about it.   

 

Thank you for the question.

 

This migration is far wider than this, it will affect all Public Key Infrastructure, RSA cryptographic algorithms, and all industries including OT applications, engineering, Operating Systems, Data Storage systems, Databases,Telecommunications systems, Communications systems, Cloud providers etc.

 

In a simplified approach:

 

1) Yes, we know you keep Asset records, Owner, location, impact of loss, and implications to the business - well extend this cryptographic algorithms throughout your business - including the algorithms used, versions, Keys, method being used etc.   So you end up with the Cryptographic Bill of Materials (CBOM) instead of a Software Bill of Materials (SBOM).  This means doing an extensive discovery, static and dynamic scanning of your applications, databases, OS, storage methods etc.   Validate the regulations and compliance conditions you have to endure by legislation - by industry and standards including PCI DSS, Government standards etc.

You will need discovery tools, OWASP already have some open source ones available.

 

2)  Check out the current NIST Approved Post Quantum Cryptography (PQC) algorithms, valid which ones are suitable for your organisation, applications, storage systems, OS, systems including IoT, IoMT, OT etc and the list grows.   Set up a test laboratory or use a commercial one such as Thales with Quantinium partnership, or others.   Those who use Hardware Security Modules (HSMs) can they migrate to Post Quantum Cryptography algorithms or do you need a bridging application or additional model to achieve this.  Or if you are lucky, your HSMs are coming up for renewals and vendors are preparing to overcome this issue.

 

3)  You need to achieve Cryptographic Agility, why because the first PQC algorithms will be released in 2024, but the second round has been publicised by NIST for the next set of algorithms in development.  You need to test your vital replacement algorithms for performance, speed and any other issues which will be bound to turn up in formal testing use cases, scenarios. Test extensively, can you substitute an alternative algorithm, to do a better job, or will your applications simply stop working. 

 

4)  And don't forget the Public Key Infrastructure Key Management will also be redundant too, so you have to shift to a Quantum Key Management system, suitable for your organisation too. 

 

Currently it is cited that it will take at least the Payments Industry 8 years at best to be able to migrate, as long as they do not delay and take this seriously.  

 

The good news is there is some Quantum Computer resistant algorithms currently existing namely AES-256 bit keys but AES-512 bit would be better in Galois Mode or GCM for storage systems - for instance Japanese regulations require that personnel data is held securely for 100 years, which is a bit extreme.

 

But think all Blockchain, cryptographic exchanges for Coins, Payment Systems will have to migrate too, or the Harvest Now, Store Later or alternatively Exploit Now, Decrypt Later brigade i.e. state actors are definitely waiting in the foreground, capturing data, with patience - imagine a ransomware attack in the future, we captured your data in 2026, but we waited until 2031 to decrypt it.

 

It is a series issue, planning and education needs to happen to prepare all organisations for this - it is not going to be an easy ride at all.  Extensive testing will be required, validation, proving the system will work, or it will have to be replaced or is it worth re-engineering to make it work vs the costs and effort etc.

 

Example: during WWII the American Verona Project was borne, to capture German and Russian communications traffic.   The same traffic was being decrypted up until the 1950s, when an American defector revealed it to the Russians!  

 

Every where we go, encryption and algorithms are being used, we need to know where they exist, how they are being used, what they are protecting, and what the impact will be if that data is revealed or exposed to the organisation or to the individual.   This data is also encrypted at EV Chargers within databases for charging purposes and for payment purposes etc.

 

These are major changes - so start planning, educating, and prepare - is my advice - there are no smoking mirrors here, it is inevitable.

 

You may not agree, but history tells us repeatedly things may not go as smoothly as many would like.  There are plenty of examples and more to come to keep us on our toes.

This is more like Y2K than SSL to TLS in my opinion, except for two factors: A) replacing cryptographic functions and libraries is an order of magnitude more complicated than expanding a date to four digits. B) The volume of software today is far greater than it was a quarter century ago.

 

Like Y2K, the biggest challenge is the "knowing what you don't know" - inventorying and code review. Unlike Y2K - perhaps because Q-Day isn't fixed on a calendar - there doesn't seem to be a lot of urgency.

@JoePete   I totally agree, the fixed date, is when the first quantum computer has sufficient memory, and processing capability to break RSA 2048-bit cryptography - when that happens the world will have a meltdown, if they have not prepared to migrate - the dark web will have trillions of data records, just waiting to be decrypted and all hell will break loose - for those organisation who shrug this thing off.

 

As the security services state:  Harvest now, Exploit Later - let the fun commence.

 

Those who have prepared, will have a ring side seat to watch the rest struggle or be doomed with a very expensive learning curve.

 

Lets hope Financial Services and Telecommunications Services, plus Supply Chain will take the priority, because without their participation it could be very dire indeed.
