Secret sharing — refers to any method for distributing a secret amongst a group of participants, each of which is allocated a share of the secret. The secret can only be reconstructed when the shares are combined together; individual shares are of no use on their … Wikipedia
Integrated Encryption Scheme — (IES) is a hybrid encryption scheme which provides semantic security against an adversary who is allowed to use chosen plaintext and chosen ciphertext attacks. The security of the scheme is based on the Diffie–Hellman problem. Two incarnations of … Wikipedia
Threshold shadow scheme — A threshold shadow scheme (also known as a threshold signature scheme or secret sharing ) is a form of secure multiparty computation in which a message is shared between several (N) people. Any piece of the message on its own is totally… … Wikipedia
Blom's scheme — is a cryptographical symmetric threshold key exchange protocol.A trusted party gives each of the n participants a secret key and a public identifier, which enables any two participants to independently create a shared key for securely… … Wikipedia
Commitment scheme — In cryptography, a commitment scheme allows one to commit to a value while keeping it hidden, with the ability to reveal the committed value later. Commitments are used to bind a party to a value so that they cannot adapt to other messages in… … Wikipedia
ElGamal signature scheme — The ElGamal signature scheme is a digital signature scheme which is based on the difficulty of computing discrete logarithms. It was described by Taher ElGamal in 1984 (see T. ElGamal, A public key cryptosystem and a signature scheme based on… … 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

Station-to-Station protocol — The Station to Station (STS) protocol is a cryptographic key agreement scheme based on classic Diffie Hellman that provides mutual key and entity authentication.In addition to protecting the established key from an attacker, the STS protocol uses … Wikipedia
Quantum cryptography — Quantum cryptography, or quantum key distribution (QKD), uses quantum mechanics to guarantee secure communication. It enables two parties to produce a shared random bit string known only to them, which can be used as a key to encrypt and decrypt… … Wikipedia
