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
[1] [2] DH is one of the earliest practical examples of public key exchange implemented within the field of cryptography. Published in 1976 by Diffie and Hellman, this is the earliest publicly known work that proposed the idea of a private key and a corresponding public key.

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 ...
In cryptography, Curve25519 is an elliptic curve used in elliptic-curve cryptography (ECC) offering 128 bits of security (256-bit key size) and designed for use with the Elliptic-curve Diffie–Hellman (ECDH) key agreement scheme.
For each joint of the kinematic chain, an origin point q and an axis of action are selected for the zero configuration, using the coordinate frame of the base. In the case of a prismatic joint, the axis of action v is the vector along which the joint extends; in the case of a revolute joint, the axis of action ω the vector normal to the rotation.
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 .
