Technology evolves, that’s why cryptography will be protected from quantum computers
One of the topics that invariably comes up in classes and conferences when discussing the use of cryptography in relation to issues such as Web3, cybersecurity, etc. is that the development of quantum computers will make cryptography as we know it unusable.
In response, my answer is that we’ll cross that bridge when we come to it. Innovation is a continuous process, and we always knew that it was only a matter of time and before cryptographic algorithms would become resistant to quantum computing. Now, a fascinating and well-explained article shows how the cryptography of the future will be quantum-safe, thanks to the use of lattice-based cryptography, resistant to attacks based on both quantum and classical computing. In fact, many lattice-based constructions are secure, on the basis that it is not possible to efficiently solve many well-known lattice problems.
Considering the relevance of cryptography, this is no small matter. Cryptography will determine the future of a huge range of financial and other transactions on an internet that will incorporate blockchains so as to guarantee security. To think that these cryptographic procedures could suddenly be rendered insecure due to the development and potential popularization of the quantum computer was never a realistic…
