Embodiment 1

[0048] see figure 1 , figure 2 , image 3 with Figure 4 , this end-to-end handheld device encryption method based on quantum cryptography comprises the following steps:

[0049] Quantum key storage: when the handheld device communicates, the handheld device that initiates the call is the calling terminal, and the called handheld device is the called terminal; the quantum communication key is stored in the handheld device through the key storage module;

[0050] Initiate a call: When encrypted communication is required, the calling end initiates an encrypted communication request to the called end;

[0051] Quantum key synchronization: After receiving the encrypted communication request and confirming the answer, the called terminal sends a key synchronization request message to the calling terminal;

[0052] Synchronization confirmation: After receiving the key synchronization request message, the calling terminal reads the quantum communication key Ksa from its key pool...

Abstract

The invention discloses an end-to-end hand-held device encryption method based on quantum cryptography and a system. The encryption method comprises following steps of storing quantum keys; initiating a call; synchronizing the quantum keys; performing synchronous confirmation; answering the call; and performing encryption communication. In the encryption communication, an MCU of a main calling end injects quantum communication keys Ksa into an encryption and decryption model; an MCU of a called end injects the quantum communication keys Ksa into the encryption and decryption model; the MCU of the called end using the quantum communication keys to encrypt the data; the encrypted data is sent out via a radio frequency module of the called end; a radio frequency module of the main calling end injects the received encrypted data into the encryption and decryption model for decryption; and after being decrypted, the data is played by a loudspeaker of the main calling end or displayed via a touch type display. The invention also discloses an end-to-end hand-held device encryption system based on quantum cryptography. The encryption method and system are highly safe, independent and easy, quick and simple to deploy.

Description

technical field [0001] The invention relates to an end-to-end quantum key synchronization method, in particular to an end-to-end handheld device encryption method and system based on quantum cryptography. Background technique [0002] While mobile calls bring convenience, they also bring security risks, and there is a possibility that voice calls may be illegally intercepted. The data transmission block diagram of the encryption and decryption of the handheld device is as follows: figure 1 shown. At present, an end-to-end handheld device encryption method and device based on quantum cryptography does not yet exist. Known encryption schemes for handheld mobile devices use a public-key system to distribute session keys through public-private key pairs. However, the security of the public-key system depends on computational complexity and cannot resist attacks from super-computing capabilities. is an attack by a quantum computer. The one-time pad encryption method using qua...
