This algorithm works according to the characteristics of the Diffie-Hellman public/private key pair. These keys are not suitable for use in an encryption algorithm. they are only used in a most important agreement like this. Authenticated Key Exchange (EFT) is the exchange of session keys in a key exchange protocol that also authenticates the identities of the parties involved (for example. B, a password, a public key or a digital certificate). If you. B you connect to a password-protected WiFi network, an authenticated key protocol for the agreement is used, in most cases the agreement with the keys authenticated by the password (PAKE). If you connect to a public wi-fi network, an anonymous key agreement is put in place. Could someone please explain in simple terms what is the difference between the generation of keys and the key agreement? In what situation I would use it. en.wikipedia.org/wiki/Key-agreement_protocol A common method for key tuning is asymmetric encryption: Alice generates a K key for an algorithm (z.B.
a 128-bit random sequence), then the crypt with Bob`s public key and sends the result to Bob. Bob decrypts it (with his private key) and receives a copy of K. At the end of the day, Alice and Bob know the same secret key K, so it`s an important deal. If we look at the details, we see that the key chord begins with a key realization entirely made by Alice. This « local-generation-then-asymetric-encryption » method is how most SSL connections are made over the Internet; Note that Diffie-Hellman cannot be described in this way, so don`t expect all important agreements to work that way. Many key exchange systems have a part that generates the key and simply sends that key to the other party — the other party has no influence on the key. The use of a key MEMORANDUM of understanding avoids some of the major distribution problems associated with these systems. The first public public key memorandum of understanding  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. Key equipment can be roughly divided into key traffic and key agreements. Start the key module of the agreement.
The parameter specifications (if any) vary depending on the underlying algorithm. If the settings are not valid, supported by the wrong class or not, an invalidAlgorithmParameterException is generated. This method also implements the first phase of the protocol on the key agreement. 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. The last option is to use a key tuning algorithm. Important agreement algorithms exchange certain public information between two parties so that they can calculate a common secret key. However, they do not exchange enough information as conversation listening companies can calculate the same freed key. Flip the name of the algorithm that was implemented by this key object. Examples of key exchange systems: Diffie-Hellman (DH) and Elliptic-curve Diffie-Hellman (ECDH), RSA-OAEP and RSA-KEM (key transport RSA), PSK (preinstalled key) ), SRP (Secure Remote Password protocol), FHMQV (Fully Hashed Menezes-Qu-Vanstone), ECMQV (Ellictic-Curve Menezes-Qu-Vanstone) and CECPQ1 (quantum-safe key agreement). Nothing in this key protocol prevents someone from imitating Bob-Alice, could exchange keys with me, I could say I`m Bob, and Alice and I could exchange encrypted data. Even if public key transmissions should not be encrypted, they should be a sign for maximum security
