Hi I would like to get some input on a quantum resistant signature based algorithm in which I tried to email out in which you will find the details on below, open to discussion. Most Quantum Resistant Algorithms are bound to be sluggish due to the complex computations used. With digital signature cryptography being my focus and implementation into blockchain the goal I have though of a suitable alternative called Two-Factor Proof of Knowledge. Simple and to the point thus removing any sluggish behavior seen in other alternatives, which sticks to the saying why fix something that is not broken? One could say that a simple equation such as x+y=z can be quantum resistant depending on the values used, so if a sha-256 is used as a value the equation above would be quantum resistant. Now what would happen when a users communicated over a distributed network as seen in a blockchain how can one prevent common attacks from taking place in a third party system? The answer is Two-Factor Proof of Knowledge or Factorized Proof of Knowledge as the more factors there are the more functionalities one can see in the signature being used. The equation used in Two-Factor Proof of Knowledge is x+e=y x+y=z In where revealing x would be the last step, something that is tied to both equations. “Scroda busts the myth that public-key cryptography on the blockchain is more secure” by Scroda https://link.medium.com/3AMqHv0rgW Would love to get some input on the matter.
