Handshake Protocol
Handshaking is the process by which two devices initiate communications. Handshaking begins when one device sends a message to another device indicating that it wants to establish a communications channel. The two devices then send several messages back and forth that enable them to agree on a communications protocol.
Handshake Protocol is responsible for the authentication and key exchange necessary to establish or resume secure sessions. When establishing a secure session, the Handshake Protocol manages the following:
- Cipher suite negotiation
- Authentication of the server and optionally, the client
- Session key information exchange.
Cipher Suite Negotiation
The client and server make contact and choose the cipher suite that will be used throughout their message exchange.
Authentication
In TLS, a server proves its identity to the client. The client might also need to prove its identity to the server. PKI, the use of public/private key pairs, is the basis of this authentication. The exact method used for authentication is determined by the cipher suite negotiated.
