Detailed explanation-1: -The RADIUS sever use a symmetric encryption method. This means that private keys are used during authentication to the server.
Detailed explanation-2: -RADIUS uses symmetric encryption.
Detailed explanation-3: -RADIUS provides for PAP authentication, in which the RADIUS client sends a clear-text password to the RADIUS server. This clear-text password is encrypted in transit. Despite nearly three decades of analysis, there have been no vulnerabilities found with this encryption.
Detailed explanation-4: -Symmetric encryption is a type of encryption where only one key (a secret key) is used to both encrypt and decrypt electronic data.
Detailed explanation-5: -Symmetric encryption is a two-way algorithm because the mathematical procedure is turned back when decrypting the message, along with using the same private key. Symmetric encryption is also referred to as private-key encryption and secure-key encryption.
