The present invention provides a method of the information secure, which includes the following steps: 1 reading a cipher and a cryptographic key 2 calculating with the cipher and the cryptographic key 3 utilizing the calculating result as the parameter for the follow-up procedure. The present invention relates to the method of utilizing the calculating result as the parameter for the follow-up procedure, and the cryptographic key and the cipher are the necessary and sufficient condition for the follow-up procedure, i.e. they are indispensable parts of the procedure, and can not "jumped" and "bypassed" and so on. The present invention takes full advantage of characteristic of computer, it charged the method of information secure guard fundamentally, and improved the reliability of safe guard.
