The key agreement refers to a key exchange form (see also key key) in which two or more users execute a protocol in order to safely release a resulting key value. An important transport protocol can be used as an alternative to the key agreement. The distinguishing feature of a key MOU is that participating users contribute equally to the calculation of the resulting common key value (unlike a user who calculates and distributes a key value to other users). Key mous that is verified by the password requires the separate implementation of a password (which may be smaller than a key) in a way that is both private and integrity. These are designed to withstand man-in-the-middle and other active attacks on the password and established keys. For example, DH-EKE, SPEKE and SRP are Diffie-Hellman password authentication variants. The first public public key memorandum of understanding [1] that meets the above criteria was the Diffie-Hellman key exchange, in which two parties jointly exposed a generator to random numbers, so that an earpiece cannot easily determine what the resulting value is used to create a common key. In cryptography, a key memorandum of understanding is a protocol in which two or more parties can agree on a key so that both influence the outcome. If this is done correctly, it prevents undesirable third parties from imposing an important decision on the appropriate parties. Protocols that are useful in practice also do not reveal to a listening party the key that has been agreed upon. The exponential key exchange itself does not indicate prior agreement or subsequent authentication between participants.
It has therefore been described as an anonymous key memorandum of understanding. A large number of cryptographic authentication schemes and protocols have been designed to provide authenticated key agreements to prevent man-in-the-middle and related attacks. These methods typically mathematically link the agreed key to other agreed data, such as the following: Many key exchange systems have a part that generates the key and simply send that key to the other party — the other party has no influence on the key.
