WebDiffie–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. WebDiffie–Hellman key exchange [nb 1] is a mathematical method of securely exchanging cryptographic keys over a public channel and was one of the first public-key protocols as …

WebMar 28, 2003 · The beauty of Diffie-Hellman is that after each party does this independently, they will both end up with the exact same value for z !. This means they now have an outstanding key for whatever encryption algorithm they decide on using for the rest of their communication. This works because: z = (g^x % p) ^x' % p = (g^x' % p) ^x % p WebExample of Three-Party Shared Secret Key Exchange.
