Q. What is Open System and Shared Key authentication?
In Open System authentication, the WLAN client does not provide its credentials to the Access Point during authentication. In Shared Key authentication, the WEP key is used for authentication in a four-step challenge-response handshake: The client sends an authentication request to the Access Point.
Q. Where is the pre-shared key for WIFI?
Contact your system support person. The person who set up your network usually keeps the WEP key or WPA/WPA2 preshared key/passphrase. If your wireless network was set up by your Internet Service Provider (ISP), then you might find the information in the documentation they provided.

Q. What is shared key in WIFI?
Shared Key Authentication (SKA) is a process by which a computer can gain access to a wireless network that uses the Wired Equivalent Privacy (WEP) protocol. With SKA, a computer equipped with a wireless modem can fully access any WEP network and exchange encrypted or unencrypted data.
Q. How is multi factor authentication implemented in OpenSSH?
Multi-factor authentication may be implemented with key pairs by entering a passphrase when the key pair is generated (see user key generation below). During authentication the user is prompted for the passphrase, which is used along with the presence of the private key on the SSH client to authenticate the user.
Q. Can a public key be shared with a private key?
The public key is what is placed on the SSH server, and may be shared without compromising the private key. When using key authentication with an SSH server, the SSH server and client compare the public keys for username provided against the private key. If the server-side public key cannot be validated against the client-side private key,
Q. What do you need to know about OpenSSH key management?
OpenSSH key management 1 About key pairs. Key pairs refer to the public and private key files that are used by certain authentication protocols. 2 Host key generation. Public keys have specific ACL requirements that, on Windows, equate to only allowing access to administrators and System. 3 User key generation. 4 Deploying the public key.
Q. How does an open system affect the surrounding system?
Due to the capability of exchanging matter between open system and surrounding, the internal mass of an open system varies with time. If matter is added, the mass will increase and if matter is removed, the mass will decrease. Figure 1: Since the mug is not covered, both energy and matter can be exchanged with the surrounding.
