We are at the beginning of the crypto universe and we already have concerns about what potentially quantum computers may bring to our society. However, there is a bigger concern that quantum computation will bring, make all previous security protocols useless.
The promise of quantum computing
Quantum computing will be another breakthrough of human invention. It brings an ever faster speed of computation and an ever-larger database that can include the information of the whole universe.
Ever faster computational power
Quantum computing will speed up the calculation speed and start to surpass previous generations of computing power. Since previous security was designed and constructed in the previous speed, the quantum speed will make those designs useless and easy to penetrate through. Your password will be cracked within hours and all your information will be stolen within a day.
Quantum computing needs quantum security
Post-quantum cryptography is a method to secure your important information and prevent the quantum cracking of your password. The cryptography will be redesigned to run on quantum computers and its algorithms will evolve to become more secure and more random.
Prepare for quantum attack
Quantum attack is still a science fiction theory. What attacks do is speed up the calculation of combining solutions and find a solution that matches what the initial algorithm was designed to generate.
Dynamic cryptography
To prevent quantum attacks, cryptographic technology has to evolve into dynamic systems that constantly improve the security and completeness of algorithms.
There are 6 ways to improve algorithms
Learning errors algorithms
Machine learning that implements algorithms to become sophisticated to learn errors and patch by itself.
Multiple cryptography
Similar to Two Factor Authentification, cryptography will have multiple security protocols with many varies to increase its security.
Hash-based algorithms
Algorithms are written by hash functions that can only be seen with private keys owners.
Self Code-based algorithms
Algorithms that are written by themselves and continue improving themselves without human interference.
Hidden secret keys
Multiple secret keys require to see codes of algorithm or secrete keys are stored offline without any possible internet connection to reach to.
Increase the size of symmetry keys
The power of harsh increases to include more data size into and generate keys with larger size of information.
Of course, there are more ways to prevent quantum attacks.
In conclusion
Prepare the post-quantum cryptography, quantum computing will progress faster to change the game plan. However, if we prepare ahead of time, we still are able to find a potential solution to prevent our security breach and secure our information.
