  • Key Wrap — constructions are a class of symmetric encryption algorithms designed to encapsulate (encrypt) cryptographic key material. The Key Wrap algorithms are intended for applications such as (a) protecting keys while in untrusted storage, or (b)… …   Wikipedia

  • Key strengthening — In cryptography, key strengthening or key stretching refer to techniques used to make a possibly weak key, typically a password or passphrase, more secure against a brute force attack by increasing the time it takes to test each possible key.… …   Wikipedia

  • Key (cryptography) — In cryptography, a key is a piece of information (a parameter) that determines the functional output of a cryptographic algorithm or cipher. Without a key, the algorithm would produce no useful result. In encryption, a key specifies the… …   Wikipedia

  • Key server (cryptographic) — In computer security, a key server is a computer mdash; typically running special software mdash; which provides cryptographic keys to users or other programs. The users programs can be working on the same network as the key server or on another… …   Wikipedia

  • Key authentication — is a problem that arises when using public key cryptography. It is the process of assuring that the public key of person A held by person B does in fact belong to person A .In traditional symmetric key cryptography, this problem wasn t an issue… …   Wikipedia

  • Key size — In cryptography, key size or key length is the size measured in bits[1] of the key used in a cryptographic algorithm (such as a cipher). An algorithm s key length is distinct from its cryptographic security, which is a logarithmic measure of the… …   Wikipedia

  • Algorithm — Flow chart of an algorithm (Euclid s algorithm) for calculating the greatest common divisor (g.c.d.) of two numbers a and b in locations named A and B. The algorithm proceeds by successive subtractions in two loops: IF the test B ≤ A yields yes… …   Wikipedia

  • Algorithm characterizations — The word algorithm does not have a generally accepted definition. Researchers are actively working in formalizing this term. This article will present some of the characterizations of the notion of algorithm in more detail. This article is a… …   Wikipedia

  • Key selection vector — The Key Selection Vector means the numerical associated with a Device Key Set and distributed by Licensor or its designee to Adopters and used to support authentication of Licensed Products and Revocation. It is considered a confidential set of… …   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

  • Selection algorithm — In computer science, a selection algorithm is an algorithm for finding the kth smallest number in a list (such a number is called the kth order statistic). This includes the cases of finding the minimum, maximum, and median elements. There are… …   Wikipedia
