In computing, a handshake is a signal between two devices or programs, used to, e.g., authenticate, coordinate. An example is the handshaking between a hypervisor and an application in a guest virtual machine .
Mutual authentication or two-way authentication (not to be confused with two-factor authentication) refers to two parties authenticating each other at the same time in an authentication protocol. It is a default mode of authentication in some protocols ( IKE , SSH ) and optional in others ( TLS ).
This protocol ensures robust encryption and data integrity, using different Initialization Vectors (IVs) for encryption and authentication purposes. [12] The 4-way handshake involves: The AP sending a random number (ANonce) to the client. The client responding with its random number (SNonce).
When a device leaves the network, the GTK also needs to be updated. This is to prevent the device from receiving any more multicast or broadcast messages from the AP. To handle the updating, 802.11i defines a Group Key Handshake that consists of a two-way handshake: The AP sends the new GTK to each STA in the network.
In computing, the Challenge-Handshake Authentication Protocol (CHAP) is an authentication protocol originally used by Point-to-Point Protocol (PPP) to validate users. CHAP is also carried in other authentication protocols such as RADIUS and Diameter. Almost all network operating systems support PPP with CHAP, as do most network access servers.
The client sends an HTTP request (method GET, version ≥ 1.1) and the server returns an HTTP response with status code 101 (Switching Protocols) on success.This means a WebSocket server can use the same port as HTTP (80) and HTTPS (443) because the handshake is compatible with HTTP.
PAP authentication is only done at the time of the initial link establishment, and verifies the identity of the client using a two-way handshake. Client sends username and password. This is sent repeatedly until a response is received from the server. Server sends authentication-ack (if credentials are OK) or authentication-nak (otherwise) [2]
The NTLM protocol suite is implemented in a Security Support Provider, which combines the LAN Manager authentication protocol, NTLMv1, NTLMv2 and NTLM2 Session protocols in a single package. Whether these protocols are used or can be used on a system, which is governed by Group Policy settings, for which different versions of Windows have ...
