  2. Key exchange - Wikipedia

    en.wikipedia.org/wiki/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.

  3. Password-authenticated key agreement - Wikipedia

    en.wikipedia.org/wiki/Password-authenticated_key...

    Password-authenticated key exchange (PAKE) is a method in which two or more parties, based only on their knowledge of a shared password, [1] establish a cryptographic key using an exchange of messages, such that an unauthorized party (one who controls the communication channel but does not possess the password) cannot participate in the method ...

  4. Diffie–Hellman key exchange - Wikipedia

    en.wikipedia.org/wiki/Diffie–Hellman_key_exchange

    Diffie–Hellman key exchange establishes a shared secret between two parties that can be used for secret communication for exchanging data over a public network. An analogy illustrates the concept of public key exchange by using colors instead of very large numbers: The process begins by having the two parties, Alice and Bob, publicly agree on ...

  5. TLS-PSK - Wikipedia

    en.wikipedia.org/wiki/TLS-PSK

    The second set use a Diffie–Hellman key exchange authenticated with a pre-shared key. The third set combine public key authentication of the server with pre-shared key authentication of the client. Usually, Transport Layer Security (TLS) uses public key certificates or Kerberos for authentication. TLS-PSK uses symmetric keys, shared in ...

  6. Key-agreement protocol - Wikipedia

    en.wikipedia.org/wiki/Key-agreement_protocol

    Symmetric key agreement (SKA) is a method of key agreement that uses solely symmetric cryptography and cryptographic hash functions as cryptographic primitives. It is related to symmetric authenticated key exchange. [7] SKA may assume the use of initial shared secrets [7] or a trusted third party with whom the agreeing parties share a secret is ...

  7. Encrypted key exchange - Wikipedia

    en.wikipedia.org/wiki/Encrypted_key_exchange

    A second paper describes Augmented-EKE, [2] and introduced the concept of augmented password-authenticated key agreement for client/server scenarios. Augmented methods have the added goal of ensuring that password verification data stolen from a server cannot be used by an attacker to masquerade as the client, unless the attacker first ...

  8. Secure Remote Password protocol - Wikipedia

    en.wikipedia.org/wiki/Secure_Remote_Password...

    The Secure Remote Password protocol (SRP) is an augmented password-authenticated key exchange (PAKE) protocol, specifically designed to work around existing patents. [1]Like all PAKE protocols, an eavesdropper or man in the middle cannot obtain enough information to be able to brute-force guess a password or apply a dictionary attack without further interactions with the parties for each guess.

  9. Supersingular isogeny key exchange - Wikipedia

    en.wikipedia.org/wiki/Supersingular_Isogeny_Key...

    p = prime for the key exchange with w A = 2, w B = 3, e A = 63, e B = 41, and f = 11. Thus p = (2 63 ·3 41 ·11) - 1. E 0 = the base (starting) curve for the key exchange = y 2 = x 3 + x Luca De Feo, one of the authors of the paper defining the key exchange has posted software that implements the key exchange for these and other parameters.
