Abstract

The invention discloses a mobile terminal secrecy system and method based on a quantum true random number. The system comprises a quantum random number generating module, a key file storage module, an encryption module, a decryption module, a key information storage module and an external file storage module, wherein the quantum random number generating module is connected with the key file storage module and used for transmitting random number key information, the key file storage module is respectively connected with the encryption module and the decryption module and used for transmitting encrypted key information and decrypted key information; the decryption module is connected with the external file storage module and used for transmitting a to-be-decrypted file and a decrypted file; the encryption module is connected with the external file storage module and used for transmitting the to-be-encrypted file and the encrypted file; the encryption module is connected with the key information storage module and used for transmitting key use condition information. The feasibility of guaranteeing the absolute security of the data through the daily application of one-time padding is provided, and the encryption of the data can be easily realized.

Description

technical field [0001] The invention relates to a technology in the field of wireless encrypted communication, in particular to a mobile terminal security system and method based on quantum true random numbers. Background technique [0002] Wireless mobile communication devices face a greater risk of eavesdropping than traditional wired communication methods, but many messages are still sent in clear text. Even if traditional encryption methods are used, which are divided into symmetric encryption algorithms such as DES, AES, RC5, etc. and asymmetric encryption algorithms such as RSA, Elgamal, etc., these can be cracked in theory. Only the one-time pad encryption method can guarantee absolute security, and the one-time pad method has long been used by the military and the government to ensure the security of top secret encrypted files. The reason why this method of ensuring absolute security is not widely used in commercial and civilian use is that the one-time pad requires...
