WireGuard uses only [7] UDP, [5] due to the potential disadvantages of TCP-over-TCP. [7] [11] [12] Tunneling TCP over a TCP-based connection is known as "TCP-over-TCP", and doing so can induce a dramatic loss in transmission performance due to the TCP meltdown problem. Its default server port is UDP 51820.
20] In this example, the sender of a message runs it through a MAC algorithm to produce a MAC data tag. The message and the MAC tag are then sent to the receiver. The receiver in turn runs the message portion of the transmission through the same MAC algorithm using the same key, producing a second MAC data tag.
The authenticator checks the response against its own calculation of the expected hash value. If the values match, the authenticator acknowledges the authentication; otherwise it should terminate the connection. In PPP, the authenticator may send a new challenge at random intervals to the peer and repeats steps 1 through 3.
This is a list of TCP and UDP port numbers used by protocols for operation of network applications. The Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) only need one port for bidirectional traffic.
The client sends an authenticated and encrypted Finished message, containing a hash and MAC over the previous handshake messages. The server will attempt to decrypt the client's Finished message and verify the hash and MAC. If the decryption or verification fails, the handshake is considered to have failed and the connection should be terminated.
Periodic – the device is scheduled to perform a periodic session, as per the PeriodicInformInterval settings; Connection request – the device responds to the server's request for a connection; Value change – value for a parameter that is being monitored has changed; Boot – after the device was reset or lost power and was reconnected;
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 .
From now on, the /idle/<session id>/<sequence #> is a polling request where the session id has been generated and returned from the server and the sequence is just a number that increments by one for every request. The appropriate response is a 200 OK, with an integer returned in the body signifying the interval time.
