fgiga [73]

Authentication protocols are usually designed and configured to create a number that will be used only once, so as to prevent replay attacks in a computer network. Thus, this number is called a <u>nonce</u>.

Authentication work based on the principle of strategically matching an incoming request from an end user or electronic device to a set of uniquely defined credentials.

In an access control list (ACL), authentication and authorization is used to ensure an end user is truly who he or she claims to be, as well as confirming that an electronic device is valid through the process of verification.
