Secure Excel Data With Authentication Protocols

An authentication protocol transfers authentication data between network entities. Discover the different types of authentication protocols with Okta.

An authentication protocol is designed to transfer authentication data between two entities.Considering the security of authentication, CHAP is more secure than PAP. Therefore, if someone uses PAP, it is recommended to use CHAP for other steps in the PPP sessions.

For each authentication protocol, well cover what the protocol is, give a detailed example, and talk through some of the weaknesses. Remember: these protocols are a baseline, so many act as jumping-off points for more advanced protocols later on.

As we can see from the illustration, Secure Excel Data With Authentication Protocols has many fascinating aspects to explore.

Kerberos is a network authentication protocol. It is designed to provide strong authentication for client/server applications by using secret-key cryptography. A free implementation of this protocol is available from the Massachusetts Institute of Technology.

Password Authentication Protocol (PAP) requires the user to provide a username and password, which are then compared to data recorded in a table to check if they match. PAP is quite similar to the traditional Unix login. It uses a two-way handshake.
