Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Aiming at the defects of low randomness of key generation and low information transmission safety in the prior art, the invention provides a communication method, a communication device, electronic equipment and a storage medium, so that the randomness of key generation and the information transmission safety are increased. The noise source of the underwater acoustic channel is complex, and has the characteristics of high delay and low speed, compared with a land communication system, the underwater acoustic communication system is more complex, and the invention takes the complex underwater acoustic communication system as an example of an application environment. The invention is described below in connection with fig. 1-5.
Fig. 1 is a schematic flow chart of a communication method provided by the present invention, as shown in fig. 1, the communication method includes:
and 103, generating a private key corresponding to the encrypted sequence based on the injection position of the artificial noise signal, so that the receiving end equipment decodes the encrypted sequence according to the private key after passing the identity authentication.
In particular, in an underwater acoustic communication system, researchers mostly adopt underwater sound as a communication carrier, and although the propagation speed of an underwater acoustic signal is low, the attenuation of the acoustic wave under water is small, which is beneficial to the complete transmission of the signal. The artificial noise technology solves the problem that a transmitting base station and a legal receiving user cannot obtain the channel state of an eavesdropper, and the eavesdropper is interfered by injecting artificial noise into one or more transmitted signals, the signal-to-noise ratio of the eavesdropper is attenuated, the channel condition of the eavesdropper is damaged, and the signal reception of a legal receiving end is not greatly influenced. The artificial noise reduces the signal-to-noise ratio of the eavesdropping channel, destroys the channel condition of the eavesdropper, and ensures that the secret key is generated at a positive rate under the assistance of the artificial noise. Even if the accurate channel state of an eavesdropper cannot be obtained, the safe transmission of the information can be realized through the interference of artificial noise, and the information leakage rate is reduced.
Herein, artificial noise refers to audio segments such as: car horns, broadcasts, and any sound segments of an audio clip.
An eavesdropper generally has high computational power, and if the encryption sequence is directly transmitted in an underwater acoustic channel, the eavesdropper may reject the encrypted sequence or destroy the encrypted sequence by a legal receiving end. The invention therefore proposes to divide the total codebook of one or more encrypted sequences randomly and independently into a number of unequal non-empty clusters by random clustering, i.e. each non-empty cluster is composed of a number of sub-clusters. Each non-empty cluster is again randomly and independently divided into a plurality of sub-clusters.
Methods of random clustering are disclosed. In the invention, the random clustering mechanism is assumed to be jointly agreed by the transmitting party and the receiving party. The purpose of random clustering is to generate a sequence number for identity authentication and to protect the encryption sequence. And sending the serial number position information of the encryption sequence by a random clustering method, and receiving the encryption sequence only after a legal receiving end passes the identity authentication of the sending end.
And the legal sending end randomly encodes the serial number of the non-empty cluster where each encryption sequence is located to obtain a first serial number corresponding to each encryption sequence, and sends the first serial number and the encryption sequence to a receiving end device so that the receiving end device can perform identity authentication according to the first serial number. An eavesdropper may listen to the channel and receive the serial number.
And the legal sending end generates a private key corresponding to the encrypted sequence based on the injection position of the artificial noise signal, and the receiving end equipment decodes the encrypted sequence according to the private key after passing the identity authentication, namely, eliminates the artificial noise symbols in the received sequence bit by bit according to the key. After one-time communication is completed, the two parties of legal communication agree on the generation mode of the secret key. And when the identity authentication is completed, the receiving end determines the information of the legal transmitting end. The key is not transmitted publicly through a channel and is known only by an authenticated recipient.
In the embodiment, an artificial noise signal is injected into the transmission signal to generate interference on an eavesdropper, so that the signal-to-noise ratio of an eavesdropping channel is attenuated to destroy the channel condition of the eavesdropper, the safe transmission of information is realized, and the information leakage rate is reduced. Meanwhile, the injection position of the artificial noise signal is used as a random source, so that the randomness of the generated key is increased.
In some embodiments, the injecting artificial noise signals into the one or more signals to be transmitted to obtain one or more encryption sequences includes:
one or more signals to be transmitted are randomly coded to obtain one or more code word sequences;
and injecting an artificial noise signal into each code word sequence, and performing confusion processing on each code word sequence injected with the artificial noise signal to generate one or more encryption sequences.
Specifically, a legal transmitting end randomly encodes one or more signals to be transmitted into a codeword by using a shannon coding method, so as to obtain one or more codeword sequences.
The set of the code word sequences is a subcodebook, the code word sequences of artificial noise signals injected into each code word sequence in the subcodebook are subjected to confusion processing, and a new encryption sequence is generated by using a confusion function. The idea of the confusion function here is: randomly injecting part of data in an input sequence into another sequence to generate a new sequence in an obfuscated mode, and storing the injected position information in a specific array.
In the embodiment, the confusion processing of artificial noise is added in the encoding process, the information concealment is improved, and the stealing difficulty of an eavesdropper is increased.
In some embodiments, the generating a secret key corresponding to the encryption sequence based on the injection position of the artificial noise signal includes:
and taking the injection position of the artificial noise signal as a random source, and mapping the random source to be a private key corresponding to the encryption sequence through a consistent uniform hash function.
And the legal sending end takes the injection position of the artificial noise signal as a random source and maps the random source to a private key corresponding to the encryption sequence through a consistent uniform hash function. Therefore, the possibility that an eavesdropper will steal a message without knowing the private key is low.
And after the identity authentication is passed, the receiving end equipment decodes the encrypted sequence according to the private key, namely, the artificial noise symbols in the receiving sequence are removed bit by bit according to the key. The unidirectionality of the global hash function prevents an eavesdropper from obtaining any relevant information about the secret key during the key verification process of the two communication parties. After one communication is completed, both parties of legal communication agree on the generation mode of the secret key. And when the identity authentication is completed, the receiving end determines the information of the legal transmitting end. The key is not transmitted publicly through a channel and is known only by an authenticated recipient.
In this embodiment, a random source of a key is generated by using randomly injected position information of artificial noise as a key codebook for key generation, so as to improve the randomness of the key.
In some embodiments, the storing the injection location of the artificial noise signal comprises:
storing the injection position of the artificial noise signal in a first-in first-out queue;
before the injecting position of the artificial noise signal is used as a random source and is mapped to a private key corresponding to the encryption sequence through a consistent uniform hash function, the method further includes:
and reading the injection position of the artificial noise signal from the first-in first-out queue.
Specifically, the injection position of the artificial noise is stored in a first-in first-out queue as a random source for subsequent key generation. And the legal sending end reads the injection position of the artificial noise signal from the first-in first-out queue, takes the injection position as a random source, and maps the random source to a private key corresponding to the encryption sequence through a consistent uniform hash function.
In this embodiment, the injection position of the artificial noise signal is stored in a first-in first-out queue, the injection position of the artificial noise signal is read from the first-in first-out queue, and the injection position of the artificial noise signal is used as a random source and is mapped to a secret key corresponding to the encryption sequence through a uniform hash function, so that the randomness of key generation and the security of signal transmission are increased.
Fig. 2 is a second schematic flow chart of the communication method provided by the present invention, as shown in fig. 2, the communication method includes:
Specifically, the legal receiving end searches for a unique sequence which belongs to the same typical sequence as the received encrypted sequence in the observed sequence, and the unique sequence is the target sequence. And decoding the first sequence number to determine the non-empty cluster sequence number of the target sequence.
Methods of random clustering are disclosed. In the invention, the random clustering mechanism is assumed to be jointly agreed by the transmitting party and the receiving party. And the receiving terminal determines the sequence number of the sub-cluster of the target sequence according to the sequence number of the non-empty cluster of the target sequence and the random clustering process, and performs identity authentication between the receiving terminal and the transmitting terminal according to the sequence number of the sub-cluster of the target sequence.
And after the identity authentication is passed, decoding the target sequence according to the private key provided by the sending end equipment, namely, performing bit-by-bit elimination on the artificial noise symbols in the receiving sequence according to the private key to obtain a signal sent by the sending end equipment.
In this embodiment, the identity authentication between the sending end and the receiving end is effectively completed according to the sequence number of the sub-cluster where the target sequence is located. After the identity authentication is passed, the target sequence is decoded according to the private key provided by the sending end device to obtain a signal sent by the sending end device, an identity authentication module is added in the information transmission process, and in order to ensure the correct transmission of the information, the identity authentication module can prevent the sent information from being intentionally tampered by an eavesdropper.
In some embodiments, the performing identity authentication according to the sequence number of the sub-cluster in which the target sequence is located includes:
and if the serial number of the sub-cluster where the target sequence is located is consistent with the serial number of the sub-cluster of the sending end equipment as the identity authentication, determining that the identity authentication between the receiving end equipment and the sending end equipment is passed.
Specifically, the identity authentication between the sending end and the receiving end is performed by the following judgment, and under the condition that the serial number of the sub-cluster where the target sequence is located is consistent with the serial number of the sub-cluster used as the identity authentication by the sending end, the identity authentication between the sending end and the receiving end is completed.
For example, the legal sending end a determines that the serial number of the non-empty cluster where the encryption sequence is located is a1 and the serial number of the sub-cluster is b1, and then randomly encodes the serial number a1 of the non-empty cluster and sends the encoded serial number to the receiving end.
The sequence observed by the legal receiving end B is V, after the serial number a1 of the non-empty cluster sent by the legal sending end is received, a unique sequence X1 which belongs to the same typical sequence with the received encryption sequence is searched from the observed sequence, and then the legal receiving end B determines the serial number of a sub-cluster where the unique sequence is located according to the random clustering process as B2, namely the serial number of the non-empty cluster determined by the unique sequence X1 through the random clustering process is a1, and the serial number of the sub-cluster is B2. When b1= b2, both parties of the legal communication complete identity authentication.
In this embodiment, by determining whether the sequence number of the sub-cluster where the target sequence is located is consistent with the sequence number of the sub-cluster used by the sending end device for identity authentication, it is determined whether the identity authentication between the receiving end device and the sending end device passes. If the two parties are consistent, the identity authentication of the two parties passes, and the communication safety is improved.
In some embodiments, the decoding, according to the private key provided by the sending end device, the encrypted sequence to obtain a signal sent by the sending end device includes:
and according to the private key provided by the sending end equipment, removing the artificial noise signals in the target sequence bit by bit to obtain the signals sent by the sending end equipment.
Specifically, according to a private key provided by the sending terminal device, the private key includes a specific position where an artificial noise signal is injected into a signal sequence, and the sending terminal performs bit-by-bit elimination on the artificial noise signal in the target sequence according to the private key to obtain a signal sent by the sending terminal.
In this embodiment, according to the private key provided by the sending end device, the artificial noise signals in the target sequence are removed bit by bit to obtain the signal sent by the sending end device, so that the randomness of generating the key is increased, and meanwhile, the security of communication is improved.
