  • Key distribution in wireless sensor networks — Key distribution is an important issue in WSN design. It is a newly developing field due to the recent improvements in wireless communications.Wireless sensor networks are networks of small, battery powered, memory constraint devices named sensor …   Wikipedia

  • Key distribution — In symmetric key cryptography, both parties must possess a secret key which they must exchange prior to using any encryption. Distribution of secret keys has been problematic until recently, because it involved face to face meeting, use of a… …   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

  • 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

  • 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

  • Diffie-Hellman key exchange — (D H) is a cryptographic protocol that allows two parties that have no prior knowledge of each other to jointly establish a shared secret key over an insecure communications channel. This key can then be used to encrypt subsequent communications… …   Wikipedia

  • Symmetric-key algorithm — Symmetric key algorithms are a class of algorithms for cryptography that use trivially related, often identical, cryptographic keys for both decryption and encryption.The encryption key is trivially related to the decryption key, in that they may …   Wikipedia

  • Session key — A session key is a single use symmetric key used for encrypting all messages in one communication session. A closely related term is traffic encryption key or TEK, which refers to any key used to encrypt messages as opposed to different uses,… …   Wikipedia
