What will be an ideal response?
Remote Authentication Dial In User Service (RADIUS) is often used in IEEE 802.1X for authentication. RADIUS consists of a client and a server. A RADIUS client is not the device requesting authentication, such as a wireless laptop. Instead, a RADIUS client is typically a device such as an AP that is responsible for sending user credentials and connection parameters in the form of a RADIUS message to a RADIUS server. The RADIUS server authenticates and authorizes the RADIUS client request, and sends back a RADIUS message response. The strength of RADIUS is that messages are never directly sent between the wireless device and the RADIUS server. This prevents an attacker from penetrating the RADIUS server and compromising security.

(Recursive Greatest Common Divisor) The greatest common divisor of integers x and y is the largest integer that evenly divides both x and y. Write a recursive function gcd that returns the greatest common divisor of x and y, defined recursively as follows: If y is equal to 0, then gcd(x, y) is x; otherwise, gcd(x, y) is gcd(y, x % y), where % is the modulus operator. [Note: For this algo- rithm, x must be larger than y.]
