Key based Authentication for Servers and Applications
Personal Authentication Protocol (PAP) is a secure authentication protocol for accessing protected resources in a server including files, directory and accounts. It works by exchanging tokens to generate unique key that will only work within a session under a limited permission. Server, applications or any connected nodes must use the same algorithm to validate and generate hashes.
It is essential for authenticating server-server and application-server which nodes require a strict access from outbound connection. It is best suitable for personal and enterprise in which closed authentication is required.
