  • Key exchange — is any method in cryptography by which cryptographic keys are exchanged between users, allowing use of a cryptographic algorithm. If Alice and Bob wish to exchange encrypted messages, each must be equipped to decrypt received messages and to… …   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

  • 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 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

  • Cryptographic key types — One of the most important aspects of any cryptographic system is key management; it is also the aspect which is most often neglected.[citation needed] A very common mistake is mixing different key types and reusing the same key for different… …   Wikipedia

  • Diffie–Hellman key exchange — (D–H)[nb 1] is a specific method of exchanging keys. It is one of the earliest practical examples of key exchange implemented within the field of cryptography. The Diffie–Hellman key exchange method allows two parties that have no prior knowledge …   Wikipedia

  • Encrypting File System — The Encrypting File System (EFS) on Microsoft Windows is a feature introduced in version 3.0 of NTFS[1] that provides filesystem level encryption. The technology enables files to be transparently encrypted to protect confidential data from… …   Wikipedia

  • Offline private key protocol — The offline private key protocol (OPKP) is a cryptographic protocol to prevent unauthorized access to back up or archive data. The protocol results in a public key that can be used to encrypt data and an offline private key that can later be used …   Wikipedia
