Webb5 jan. 2024 · A two-party key exchange protocol has been a fundamental building block of cryptography and network security. It allows any two parties to share a common session key over an insecure channel. Since its early introduction in 1976, the Diffie–Hellman key exchange protocol has been the most famous key exchange protocol. WebbIn cryptography, it is common to talk about keys (usually a short piece of data) to refer to special inputs of a cryptographic algorithm. The most common keys are those used for data encryption; however, other types of keys exist for different purposes.

WebbDiffie–Hellman key exchange. In the Diffie–Hellman key exchange scheme, each party generates a public/private key pair and distributes the public key. After obtaining an authentic copy of each other's public keys, Alice and Bob can compute a shared secret offline. The shared secret can be used, for instance, as the key for a symmetric cipher. WebbIn cryptography, a shared secret is a piece of data, known only to the parties involved, in a secure communication. This usually refers to the key of a symmetric cryptosystem. The shared secret can be a password, a passphrase, a …

The key exchange problem describes ways to exchange whatever keys or other information are needed for establishing a secure communication channel so that no one else can obtain a copy. Historically, before the invention of public-key cryptography (asymmetrical cryptography), symmetric-key cryptography utilized a single key to encrypt and decrypt messages. For two parties to communicate confidentially, they must first exchange the secret key so that each party is abl… Webbasymmetric cryptography (public key cryptography): Asymmetric cryptography , also known as public key cryptography, uses public and private keys to encrypt and decrypt data.
