A7 B7 V. Description of the Invention (5.1 Field of the Invention The present invention relates to a method of encrypting communication between communication devices to prevent eavesdropping, and in particular to a method of closing a telephone The communication is encrypted to prevent eavesdropping. 25-2 BACKGROUND OF THE INVENTION Employees' cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs print general communication systems when communicating, because the transmission has not been specially processed. Anyone who receives this signal in the process can directly understand the message. Therefore, if an eavesdropper wants to eavesdrop on two communication devices, take the phone as an example, the eavesdropper only needs to pass between the two phones. To another communication device, you can receive the signal and use it to obtain the message transmitted between the two phones. The communication method is easy to be eavesdropped, especially wireless communication, and even to eavesdrop on its communication content. General eavesdropping of traditional communication systems Prevent the device and solve the problem that the communication system is too easy to be eavesdropped. Therefore, the traditional anti-eavesdropping device is to divide the communication signal between the two communication systems into several segments. After the frequency spectrum signal is shifted, the frequency of this number of bands is adjusted to return to its original frequency spectrum position, and the original information contained in the communication signal is demodulated. Therefore, even if it is a communication signal, it does not know that the communication signal is divided into numbers. How to adjust the position of these spectrums on the spectrum, so the transmitted signals are transmitted in parallel and the communication lines included in the signals are used to communicate between them. Therefore, the traditional system that is easy to be intercepted is the communication system required. The spectrum is divided into the receiving end, so that the eavesdropper at the receiving end cannot demodulate after receiving the spectrum {Please read the note on the back »before filling this page) 10 ^.

Description of the invention (the information contained in the communication signal. However, the technology used in traditional anti-eavesdropping devices is analog And its method has some disadvantages. For example, when adjusting the communication signal to its frequency position, it is used in traditional anti-eavesdropping devices. The frequency switching device is implemented, so the frequency switching method is fixed in the traditional anti-eavesdropping device. If the eavesdropper also has the same brand or the same frequency switching method device, the eavesdropper can still The received communication signal is processed to obtain the information in it. Even if the eavesdropper has a PBX terminal, the eavesdropper can still hear the call directly. Especially because of technical problems, there are not many methods for spectrum switching. Therefore, even if the eavesdroppers do not have the same brand of anti-eavesdropping device, they can eavesdrop and obtain the message transmitted between the two communication devices. In addition, for the traditional analog anti-eavesdropping device, it is still necessary to The calibration of the level can enable the traditional anti-eavesdropping device to operate. Another traditional anti-bugging device is digital, which is a kind of digital security device. Although it can prevent the call content from being heard directly by the PBX terminal. However, the disadvantage is that the password is fixed and cannot be changed, so the listener may still crack the password and eavesdrop. In addition, there is still a type that can be changed, but it must pass the password to the other party on the phone line so that the other party can extract the information in the communication signal based on this, so that the communication can be performed. But this method may still be cracked because it is received by eavesdroppers when transmitting the password to the other party, so that eavesdroppers can still eavesdrop. In addition, the signal transmission wheel in the middle of the communication system using such a digital security device must use a very high-quality communication line, otherwise the two correspondents cannot communicate into a private paper.

Description of the invention () Before the news, the connection between it and the communication system and the object to be communicated is shown in the connection situation in Figure 1. The difference is the first end 10 The telephone line socket 28 'of the encrypted digital security device 20 must be directly and electrically coupled with the telephone line socket of the encrypted digital security device 25 of the second end 15 to directly transmit the individual public key to the other party' and store it in the other party. The public key list (pub | jc key directory) is relative to the address of the communication partner β. The gold record generation method for the first exchange of gold coins is randomly generated by the RSA algorithm. If the first communication is performed later, That is, the information containing the other party's public Jing Jing is encrypted with its own private key and the encrypted message is transmitted to the other party. At the same time, the other party does the same action, sends an encrypted message to the party, and then uses the party's private key. Decrypt the received encrypted message. If you get your own public key, it means that this communication process needs to be confidential. In this communication, your own encrypted communication will be used by Pei Zhi. After the audio signal of the person has been digitized, the signal is extracted and combined with the password randomly generated by the RSA algorithm to generate another pair of his public key and private gold. Similarly, the other party also does the same. During the communication process, the two parties will exchange the public key generated later and store it in the public gold list. From the above, it can be known that the encrypted digital security system of the present invention can change the password each time, and through the structure of the RSA algorithm such as the public key and the private key, the password of the present invention is not leaked during transmission, so its communication is very secure. This case does not generate the password completely according to the traditional RSA algorithm. This case extracts a part of it and cooperates with the method used in this case to prevent the generated garbled code from appearing in order because the RSA algorithm is cryptography.
