  • One-way compression function — In cryptography, a one way compression function is a function that transforms two fixed length inputs to an output of the same size as one of the inputs. The transformation is one way , meaning that it is difficult given a particular output to… …   Wikipedia

  • One-way function — Unsolved problems in computer science Do one way functions exist? In computer science, a one way function is a function that is easy to compute on every input, but hard to invert given the image of a random input. Here easy and hard are to be… …   Wikipedia

  • One-way voice link — A one way voice link (OWVL) is a shortwave radio communication method used by spy networks to communicate with agents in the field. This system often employs recorders to transmit pre recorded messages in real time or in burst transmissions,… …   Wikipedia

  • One-way quantum computer — The one way or measurement based quantum computer is a method of quantum computing that first prepares an entangled resource state, usually a cluster state or graph state, then performs single qubit measurements on it. It is one way because the… …   Wikipedia

  • One-way encryption — In cryptography, the term one way encryption has been used to refer to a number of different things: *One way function, a function difficult to invert. Note that encryption is, by definition, reversible. Hence, the term one way encryption is… …   Wikipedia

  • History of cryptography — The history of cryptography begins thousands of years ago. Until recent decades, it has been the story of what might be called classic cryptography that is, of methods of encryption that use pen and paper, or perhaps simple mechanical aids. In… …   Wikipedia

  • Public-key cryptography — In an asymmetric key encryption scheme, anyone can encrypt messages using the public key, but only the holder of the paired private key can decrypt. Security depends on the secrecy of that private key …   Wikipedia

  • Salt (cryptography) — In cryptography, a salt consists of random bits, creating one of the inputs to a one way function. The other input is usually a password or passphrase. The output of the one way function can be stored rather than the password, and still be used… …   Wikipedia
