Abstract

Provided is an information encryption method of high security. The method includes that a message to be encrypted and sent is chosen, after data to be sent is encrypted, a digital secret key is mutually discussed according to a respective secret key password; a fake message chart is stored in a terminal device. The chosen message is combined with the inputted password to generate encrypted data. A symmetrical encryption technology is used for carrying out encryption over textual contents of the message so that the text contents are displayed an inner section of one message inside the fake message chart, at least a first encrypted data to be decrypted is chosen from the encrypted data. The encrypted message is forged into a normal message through the fake message chart; the secret key of the encrypted data is changed from the secret key of a mobile terminal of senders to the secret key of the objective mobile terminal, and then is sent to the objective mobile terminal and the security if the message communication is increased.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an information encryption method with high security. Background technique [0002] Confidential communication, computer keys, anti-copy floppy disks, etc. all belong to information encryption technology. Encryption in the communication process mainly uses passwords. In digital communication, computers can use encryption methods to change the digital structure of the load information. Computer information protection is mainly based on software encryption. At present, the most popular encryption systems and encryption algorithms in the world are: RSA algorithm and CCEP algorithm. [0003] In order to prevent cracking, encryption software often uses hardware encryption and encrypted floppy disks. Some software products often have a small hard card, which is the hardware encryption method. Use laser perforation on the floppy disk to make the software storage area have some ...
