The four parameters of classic DH convention are shown in red text, which are θ i, d i, a i, α i. With those four parameters, we can translate the coordinates from O i–1 X i–1 Y i–1 Z i–1 to O i X i Y i Z i. The following four transformation parameters are known as D–H parameters: [4] d: offset along previous z to the common normal
Diffie–Hellman (DH) key exchange [nb 1] is a mathematical method of securely generating a symmetric cryptographic key over a public channel and was one of the first public-key protocols as conceived by Ralph Merkle and named after Whitfield Diffie and Martin Hellman.
For example, in the Diffie–Hellman key exchange, an eavesdropper observes and exchanged as part of the protocol, and the two parties both compute the shared key . A fast means of solving the DHP would allow an eavesdropper to violate the privacy of the Diffie–Hellman key exchange and many of its variants, including ElGamal encryption .
This intuitive notion can be formally stated by saying that the following two probability distributions are computationally indistinguishable (in the security parameter, = ()): ( g a , g b , g a b ) {\displaystyle (g^{a},g^{b},g^{ab})} , where a {\displaystyle a} and b {\displaystyle b} are randomly and independently chosen from Z q ...
Curve25519 is a popular set of elliptic curve parameters and reference implementation by Daniel J. Bernstein in C. Bindings and alternative implementations are also available. Curve448 , an elliptic curve potentially offering 224 bits of security, developed by Mike Hamburg of Rambus Cryptography Research.

one free direction vector , giving the line a direction as well as a sense. Each point x {\displaystyle x} on the line is given a parameter value t {\displaystyle t} that satisfies: x = p + t d {\displaystyle x=p+td} .
