摘要：Preventing malicious code from reading an authenticator and being falselyauthenticated using the read authenticator. Authenticator accepting period detectionmeans detects an authenticator accepting period during which inoperativeness of all

unauthenticated programs is guaranteed. Program executing means transmits its

authenticator only during the authenticator accepting period. After authentication meansis authenticated as genuine, the authentication means computes a one-way function valueof the authenticator received from the program executing means and compares the one-way function value X with a stored value Y for the program executing means. If X=Y, thenthe authentication means authenticates the program executing means.
