Abstract

The invention discloses an information double-secret-key encryption method. The method includes the following steps that 1, each number of 0 to 9 and each letter of A to Z are converted into 4-bit or 6-bit binary digits respectively, and the 4-bit or 6-bit binary digits are two binary digits with the same digit sequentially; 2, to-be-encrypted information is converted into corresponding two sets of binary digits to serve as a first binary password and a second binary password; 3, a magnetic metal ion modified rare earth up-conversion luminescence nano-material reacts with a compound, a reactant is obtained, optical, thermal and magnetic signal changes of the reactant are measured, if the signal changes are forward changes, it is recorded as 1, otherwise, it is recorded as 0; 4, corresponding relationships are established between the first binary password and the second binary password and the light, heat and magnetism signal changes and the compound, and a first secret key and a second secret key are obtained respectively. The adopted material is simple, and the encryption effect can be achieved simultaneously through multiple signals. Due to the existence of the two sets of secret keys, double-secret-key encryption can be achieved, and confidentiality of information is promoted.

Description

technical field [0001] The invention belongs to the technical field of information encryption and storage, and in particular relates to a double-key encryption method based on nanomaterials with composite signals and binary. Background technique [0002] The encryption of information is a means of processing the original information data with a special algorithm, so that even if an unauthorized user obtains the encrypted information, he still cannot understand the content of the information because he does not know the decryption method. There are applications in other fields. Where the method of decryption is a parameter is called a key. It is a parameter entered in an algorithm that converts plaintext to ciphertext or ciphertext to plaintext. The double-key encryption technology has a pair of keys, and only obtaining one of the keys cannot decipher the hidden information, which has better confidentiality than single-key encryption. Therefore, establishing a new type of ...
