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.
Internet Key Exchange (IKE) is a standard protocol used to set up a secure and authenticated communication channel between two parties via a virtual private network . The protocol ensures security for VPN negotiation, remote host and network access.
Feb 22, 2024 · Key exchange is vital for secure file transfers, enabling two parties to share symmetric keys over insecure networks like the Internet.
The Diffie–Hellman key exchange method allows two parties that have no prior knowledge of each other to jointly establish a shared secret key over an insecure channel. This key can then be used to encrypt subsequent communications using a symmetric-key cipher .
Aug 24, 2023 · The Diffie-Hellman key exchange was one of the most important developments in public-key cryptography. Find out why it's still such an important aspect of internet security.
In cybersecurity and antivirus contexts, key exchange refers to the process of exchanging cryptographic keys, which are used to protect the confidentiality, authentication, integrity, and non-repudiation of digital data.
Diffie–Hellman Key Exchange (DHKE) is a cryptographic method to securely exchange cryptographic keys (key agreement protocol) over a public (insecure) channel in a way that overheard communication does not reveal the keys. The exchanged keys are used later for encrypted communication (e.g. using a symmetric cipher like AES).
