Abstract
Upon receiving a request to clear or reset a terminal, the terminal displays a random number, the random number is placed in a regular file and signed by a private key to created a signed clear file, the clear file is authenticated, and the original random number is replaced by a new random number, thereby ensuring the authenticity of the clear or reset request while protecting the terminal from replay attacks.
