The Diffie−Hellman protocol, ingenious in its simplicity, is still the major solution in protocols for generating a shared secret in cryptography for e-trading and many other applications after an impressive number of decades.However, lately, the threat from a future quantum computer has prompted successors resilient to quantum computer-based attacks.Here, an algorithm similar to Diffie−Hellman is presented.In angilina white contrast to the classic Diffie−Hellman, it involves floating point numbers of arbitrary size in the generation of a shared secret.
This can, in turn, be used for encrypted communication based on symmetric cyphers.The validity of hp pavilion 15-eg1053cl the algorithm is verified by proving that a vital part of the algorithm satisfies a one-way property.The decimal part is deployed for the one-way function in a way that makes the protocol a post-quantum key generation procedure.This is concluded from the fact that there is, as of yet, no quantum computer algorithm reverse engineering the one-way function.
An example illustrating the use of the protocol in combination with XOR encryption is given.
