Quantum resistant cryptography, which is also known as post-quantum cryptography is at the center of a storm raging in the world of cryptography that is on high alert about a monstrous security threat looming over not just classical computer systems but quantum systems as well. To make matters worse, this disruptive cryptography will be able to correlate with existing networks and protocols. So what exactly is the monstrous nature of this particular type of cryptography that has sent all the great minds running for cover? Well, it begins with what are known quantum computers that have the ability exploit highly complex mechanical fields to get around mathematical barriers that are beyond the scope of ordinary computers to process.
In the world of cryptography, such quantum resistant capability can have the effect of multiple tornados on the loose. It’s no longer a question of whether such quantum computers will ever come into the market but when they will arrive and crash into cryptosystems that are secured with the public-key system that are currently in use. The research that is going on at present to get an idea of the magnitude of the problem is nowhere near figuring out the scale at which entire eco-systems will fall prey to this monstrous juggernaut that is already rolling. However, the monster is still in the making and the fearsome mathematical capabilities it will employ are in the very reservoir of knowledge that is accessible to those who are working on building the defenses under the public platform called post-quantum cryptography.
The big question now is, how much time does the cryptography industry has to erect its defenses against this raging quantum resistant monster. Till a few decades ago, there was no clear understanding of how fast this capability can creep into the crypto-computer systems but now the mist is clearing up with the cryptocurrency market growing so fast. The blockchain technology itself is the next level of computing if the prevalent base of computer systems is considered. To think that this next level of computing itself is under threat from a superior system which appears to be a runaway clone of the blockchain system is quite intriguing. After all the attacks will only target the gaps and loopholes in the present protocol and hence will have most of the characteristics of the prey systems factored into their systems. Preparations to meet this challenge before it becomes a crisis will bear fruit if the right amount intensity and commitment is shown.
