Diffie–Hellman (DH) key exchange [nb 1] is a mathematical method of securely exchanging cryptographic keys 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. [1] [2] DH is one of the earliest practical examples of public key exchange implemented ...
Definition. A digital signature scheme typically consists of three algorithms: A key generation algorithm that selects a private key uniformly at random from a set of possible private keys. The algorithm outputs the private key and a corresponding public key. A signing algorithm that, given a message and a private key, produces a signature.
PDF graphics use a device-independent Cartesian coordinate system to describe the surface of a page. A PDF page description can use a matrix to scale, rotate, or skew graphical elements. A key concept in PDF is that of the graphics state, which is a collection of graphical parameters that may be changed, saved, and restored by a page ...
Control key. In computing, a Control key Ctrl is a modifier key which, when pressed in conjunction with another key, performs a special operation (for example, Ctrl + C ). Similarly to the Shift key, the Control key rarely performs any function when pressed by itself. The Control key is located on or near the bottom left side of most keyboards ...
Declaration of Alma-Ata was adopted at the International Conference on Primary Health Care (PHC), Almaty (formerly Alma-Ata), Kazakh Soviet Socialist Republic (present day Kazakhstan ), Soviet Union 6–12 September 1978. [1] It expressed the need for urgent action by all governments, all health and development workers, and the world community ...
The Socratic method (also known as method of Elenchus or Socratic debate) is a form of argumentative dialogue between individuals, based on asking and answering questions.. In Plato's dialogue "Theaetetus", Socrates describes his method as a form of "midwifery" because it is employed to help his interlocutors develop their understanding in a way analogous to a child developing in the womb.
138. ISBN. 978-1-61720-383-1. The Master Key System is a personal development book by Charles F. Haanel that was originally published as a 24-week correspondence course in 1912, and then in book form in 1916. [1] The ideas it describes and explains come mostly from New Thought philosophy.
Public key certificate. In cryptography, a public key certificate, also known as a digital certificate or identity certificate, is an electronic document used to prove the validity of a public key. [1] [2] The certificate includes the public key and information about it, information about the identity of its owner (called the subject), and the ...
Answer set programming ( ASP) is a form of declarative programming oriented towards difficult (primarily NP-hard) search problems. It is based on the stable model (answer set) semantics of logic programming. In ASP, search problems are reduced to computing stable models, and answer set solvers —programs for generating stable models—are used ...
