What Authentication Protocol Sends Authentication Information in Cleartext Without Encryption?

Answer:

The Password Authentication Protocol sends authentication information in clear text without encryption.

Authentication protocol:

It is a kind of computer communication protocol or cryptographic protocol. It is particularly planned to transmit data authentication between two entities. It allows to receiving entity to verify the connecting entity means the client connects to a server. It also verifies itself to the connecting entity (server connect to client) by announcing the needed type of information for verification. To secure communication in computer networks this is the most important layer of protection.

Authentication Protocol Purpose:

To secure the information from an unauthorized person this protocol is needed. In the computing world, it’s very easy to steal someone’s information or identity. To avoid this special verification is invented to verify the personal data who really, he is. The main postulate of this protocol is.

• It includes two or more than two parties and everyone knows that protocol is advanced.
• All the parties must follow the protocol.
• The protocol should be simple every step is precisely defined.
• It must be complete it includes a particular action for every situation.

Very basic threats to protocols are eavesdropping, dictionary attacks, replay tracks, and force attacks. Most of the authentication protocols are complicated to protect from attacks.

Password authentication protocol (PAP):

Password authentication protocol is a weak authentication protocol. It does not encode any data and it transfers clear authentication credentials. It is the oldest verification protocol. In authentication, the client sends the package with username and password at the start of connection until the request is accepted the client repeats the authentication request. This is highly insecure because it is repeatedly clear making it vulnerable to attacks like eavesdropping attacks. It is widely supported if execution offers a strong authentication method is applied before password authentication protocol. Mixed authentication is not expected for example same clients use both PAP and CHAP.

Challenge- handshake authentication protocol is come terms by password authentication protocol by sending the password in Cleartext.
