- Diffie–Hellman key exchange - Wikipedia
With Diffie–Hellman key exchange, two parties arrive at a common secret key, without passing the common secret key across the public channel Diffie–Hellman (DH) key exchange[nb 1] is a mathematical method of securely generating a symmetric cryptographic key over a public channel and was one of the first protocols as conceived by Ralph Merkle and named after Whitfield Diffie and Martin
- Elliptic-curve Diffie–Hellman - Wikipedia
The key, or the derived key, can then be used to encrypt subsequent communications using a symmetric-key cipher It is a variant of the Diffie–Hellman protocol using elliptic-curve cryptography
- Key exchange - Wikipedia
Key exchange Key exchange (also key establishment) is a method in cryptography by which cryptographic keys are exchanged between two parties, allowing use of a cryptographic algorithm In the Diffie–Hellman key exchange scheme, each party generates a public private key pair and distributes the public key
- ElGamal encryption - Wikipedia
The algorithm first performs a Diffie–Hellman key exchange to establish a shared secret , then uses this as a one-time pad for encrypting the message ElGamal encryption is performed in three phases: the key generation, the encryption, and the decryption The first is purely key exchange, whereas the latter two mix key exchange computations with message computations
- Oakley protocol - Wikipedia
The Oakley Key Determination Protocol is a key-agreement protocol that allows authenticated parties to exchange keying material across an insecure connection using the Diffie–Hellman key exchange algorithm
- Forward secrecy - Wikipedia
Alice and Bob use a key exchange algorithm such as Diffie–Hellman, to securely agree on an ephemeral session key They use the keys from step 1 only to authenticate one another during this process
- Elliptic-curve cryptography - Wikipedia
National Institute of Standards and Technology (NIST) has endorsed elliptic curve cryptography in its Suite B set of recommended algorithms, specifically elliptic-curve Diffie–Hellman (ECDH) for key exchange and Elliptic Curve Digital Signature Algorithm (ECDSA) for digital signature
- Public-key cryptography - Wikipedia
In the Diffie–Hellman key exchange scheme, each party generates a public private key pair and distributes the public key of the pair After obtaining an authentic (n b , this is critical) copy of each other's public keys, Alice and Bob can compute a shared secret offline
