Abstract
The present invention discloses a secret key distribution device based on chaos synchronization. The device comprises a chaotic signal generation module, an analog-to-digital conversion module, and an error correction module. The chaotic signal generation module inputs an excitation signal, and outputs a random chaotic analog signal; the analog-to-digital conversion module inputs the random chaotic analog and outputs a random chaotic digital signal; the error correction module inputs a random chaotic digital signal, namely a secret key, in accordance with the random chaotic digital signal; and the chaotic signal generation module, the analog-to-digital conversion module, and the error correction module are successively connected. In the device, the sender and the receiver enable secret key spread and distribution without information sharing before a ciphertext is sent and received. The confidential capacity is unrelated to computing power. The sender and receiver only need this device to enable secret key distribution.
Description
Technical field
The present invention relates to a kind of secret key dispensing device based on Chaotic Synchronous, belong to private communication technology field.
Background technology
Secret key safety and the distribution of secret key are the most important links of secure communication, once secret key dissemination system is destroyed, whole secrecy system will become meaningless.At present, a kind of secret key distribution technology is mainly RSA cryptographic algorithms, it is a kind of technology based on large number factorization difficulty, the benefit of this technology is that the transmission of ciphertext and recipient only need a shared PKI and do not need to propagate the propagation that other information just can realize password, and the shared approach of PKI can disclose arbitrarily, weak point is that its secret is the difficulty of factorization, once computing capability promotes, will have no secret can say.
Summary of the invention
Object: in order to overcome the deficiencies in the prior art, the invention provides a kind of secret key dispensing device based on Chaotic Synchronous.
Technical scheme: for solving the problems of the technologies described above, the technical solution used in the present invention is:
Based on a secret key dispensing device for Chaotic Synchronous, comprise chaotic signal generation module, analog-to-digital conversion module, correction module, described chaotic signal generation module input signal, export Stochastic Chaos analog signal; Described analog-to-digital conversion module input Stochastic Chaos analog signal output Stochastic Chaos digital signal; Described correction module input Stochastic Chaos digital signal exports consistent Stochastic Chaos digital signal, is secret key; Described chaotic signal generation module, analog-to-digital conversion module, correction module connect successively.

Beneficial effect: the secret key dispensing device based on Chaotic Synchronous provided by the invention, the chaotic signal generation module of the design can produce chaotic signal under a certain bias, and the device of similarity condition manufacture can produce the chaotic signal of height correlation under identical excitation, utilize these relevant chaotic signals, realize the distribution of secret key flexibly recipient and transmit leg, upgrade, store.The design is fixed against the non-reproduction of device, solves the shortcoming premised on computing capability deficiency of existing secret key dissemination system.Meanwhile, the design, based on conventional semiconductor processing, can realize low cost, reliable, compatible good secret key dissemination system.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
As shown in Figure 1, a kind of secret key dispensing device based on Chaotic Synchronous, comprises chaotic signal generation module 1, analog-to-digital conversion module 2, correction module 3, described chaotic signal generation module 1 input signal, exports Stochastic Chaos analog signal; Described analog-to-digital conversion module 2 inputs Stochastic Chaos analog signal output Stochastic Chaos digital signal; Described correction module 3 inputs Stochastic Chaos digital signal and exports consistent Stochastic Chaos digital signal, is secret key; Described chaotic signal generation module 1, analog-to-digital conversion module 2, correction module 3 connect successively.
Described chaotic signal generation module 1 adopts superlattice material.
Preferably, also comprise data encryption and synchronization module 4, described data encryption and synchronization module 4 input consistent Stochastic Chaos digital signal and clear data, export synchronous ciphertext signal.
Concrete occupation mode is as follows:
The equipment of signalling and receiving side signal is provided with the secret key dispensing device based on Chaotic Synchronous, transmit leg device start power supply, chaotic signal generation module starts to produce chaotic signal under incentive action, and chaotic signal is sent into analog-to-digital conversion module, analog-to-digital conversion module becomes digital signal chaotic signal and digital signal is outputted to correction module, and correction module adopts block code mode to carry out digital signal to process the data after exporting error correction.Subsequently, the data after error correction outwards send as secret key is synchronous together with clear data with synchronization module by data encryption.
Receiver equipment receives the ciphertext that transmit leg equipment sends, and utilizes the secret key dispensing device based on Chaotic Synchronous, starts same secret key under same incentive action, and recipient utilizes same secret key to complete the deciphering of ciphertext.
Transmit leg and recipient do not need shared information just can realize secret key propagation distribution before ciphertext sends and receives, and secret ability and computer computation ability have nothing to do.Transmit leg and recipient only need to arrange the distribution that this device just can realize secret key.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
