ABSTRACT:
Preventing malicious code from reading an authenticator and being falsely authenticated using the read authenticator. Authenticator accepting period detection means 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 means is authenticated as genuine, the authentication means computes a one-way function value of 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, then the authentication means authenticates the program executing means.
