Explanation

A challenge/response authentication process is a method of verifying the identity of a user or device by sending a challenge, such as a random number, and expecting a valid response, such as a hash based on the user's password and the challenge. This prevents the password from being transmitted in clear text and reduces the risk of replay attacks. Using a password history blacklist, presenting distorted graphics of text for authentication, and requiring the use of non- consecutive numeric characters are not characteristics of a challenge/response authentication
