A method for generating intelligent password protection

Abstract

The invention discloses a method for generating intelligent password protection, comprising the steps as follows: A, receiving a plaintext with a transmitting end, converting the plaintext to a first ciphertext via a transfer function, then decomposing the first ciphertext into a plurality of character fields; B, generating a random number via a random function, choosing one character field by using the random number, transmitting the character field to a receiving end, generating a transfer matrix at the receiving end via using the character field and transmitting the transfer matrix to the transmitting end; C, performing secondary encryption to the plaintext with the transmitting end by using the transfer matrix to form a second ciphertext and transmitting the second ciphertext to the receiving end; and D, deciphering the second ciphertext with the receiving end by using the transfer matrix. The method of the invention can overcome the shortcoming of the prior art and can be used for forming a comprehensive encryption means by combining the plaintext itself and an encryption method through using the manner that plaintext itself is encrypted, which greatly improves the safety of password protection.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a method for generating intelligent password protection. Background technique [0002] As people pay more attention to information security, there are more and more password protection methods. But most of the existing methods for password protection are limited to adopting some encryption method to encrypt the plaintext, and the difference is only that the specific encryption methods are different. In this way, the protection of passwords only depends on the encryption method itself, and the security cannot be guaranteed. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an intelligent password protection generation method, which can solve the deficiencies of the prior art. By using the plaintext itself to encrypt, the plaintext itself and the encryption method are combined to form a comprehensive encrypt...

Problems solved by technology

However, most of the existing methods for password protection are limited to encrypting the plaintext by a certain encryption method, and the difference is only in the specific encryption method.

In this way, the protection of passwords only depends on the encryption method itself, and the security cannot be guaranteed.
