Explanation

TLS (Transport Layer Security) is the protocol designed specifically to provide secure authentication, encryption, and data integrity over non-secure networks such as the internet. It uses a handshake process to negotiate encryption algorithms and authenticate one or both parties via digital certificates, then encrypts the session data. RADIUS is an AAA (Authentication, Authorization, Accounting) protocol but does not itself provide general-purpose transport encryption. PPTP is a VPN tunneling protocol that is considered weak and outdated due to known security vulnerabilities. HTTP is an unencrypted, plaintext web protocol with no built-in security.
