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 application.
Referring to fig. 1, fig. 1 is a first flowchart of a method for peer-to-peer short message transmission according to an embodiment of the present disclosure.
The non-peer-to-peer short message transmission method provided by the embodiment of the application is applied to a software client in a sending terminal, and can comprise the following steps:
step S101: and acquiring a target short message to be sent.
In practical application, a software client in the sending terminal may first obtain a target short message to be sent, specifically, the short message information input by the user may be used as the target short message under the operation of the user, and the type and content of the target short message may be determined according to actual needs. In addition, the terminal may be a mobile phone of the user or the like.
Step S102: and acquiring the identification information of the receiver corresponding to the target short message.
In practical application, after acquiring a target short message to be sent, a software client in a sending terminal may acquire identification information of a receiver corresponding to the target short message, for example, after a user clicks on storage information of the receiver stored in the sending terminal, identification information of the receiver and the like may be determined according to the storage information of the receiver clicked by the user, so as to encrypt the target short message based on the identification information of the receiver in the following.
It should be noted that the type of the identification information of the receiving party may be determined according to actual needs, for example, the identification information of the receiving party may be a mobile phone number of the receiving party, a user ID of the receiving party, and the like, and the application is not specifically limited herein.
Step S103: and determining a user public key of the receiver, wherein the user public key of the receiver is generated based on the identification information of the receiver and a preset public key base.
In practical application, after acquiring the identification information of the receiver corresponding to the target short message, the software client in the sending terminal can determine the user public key of the receiver, and in the application, the user public key of the receiver is generated based on the identification information of the receiver and a preset public key base.
It should be noted that, in the process of generating the user public key of the receiver based on the identification information of the receiver and the preset public key base, the identification information of the receiver and the user public key of the receiver generated by the preset public key base may be called by combining a public key identification algorithm, and the like; in addition, the user public key of the receiver is generated based on the identification information of the receiver, so that the user public key of the receiver only belongs to the receiver, and the uniqueness of the user public key of the receiver is ensured.
Step S104: and encrypting the target short message based on the user public key of the receiver to obtain the target encrypted short message.
Step S105: and transmitting the target encrypted short message to a receiving terminal of a receiving party.
In practical application, after determining the user public key of the receiver, the software client in the sending terminal can encrypt the target short message based on the user public key of the receiver to obtain the target encrypted short message, and transmit the target encrypted short message to the receiving terminal of the receiver.
It should be noted that, after the receiving terminal of the receiving party receives the target encrypted short message, the software client in the receiving terminal needs to determine the user private key of the receiving party corresponding to the receiving terminal after detecting that the receiving terminal receives the encrypted short message, and the user private key of the receiving party is generated based on the identification information of the receiving party and the preset private key base; and the target encrypted short message is decrypted based on the user private key of the receiver to obtain the target short message, and then the target short message can be directly displayed, or the target short message can be displayed by means of the short message function of the terminal. That is, in the present application, the user keys (the user private key and the user public key) are generated by the corresponding user identification information and the key bases (the public key base and the private key base). In addition, in a specific embodiment, the key base in the present application may include an 8 × 8 key generation matrix, such as a public key generation matrix with a public key base of 8 × 8, and the like, so that the user key may be generated quickly by using the 8 × 8 key generation matrix.
The application provides a non-peer-to-peer short message transmission method, which is applied to a software client in a sending terminal to obtain a target short message to be sent; acquiring identification information of a receiver corresponding to the target short message; determining a user public key of a receiver, wherein the user public key of the receiver is generated based on the identification information of the receiver and a preset public key base; encrypting the target short message based on the user public key of the receiver to obtain a target encrypted short message; and transmitting the target encrypted short message to a receiving terminal of a receiving party. In the application, the software client in the sending terminal can encrypt the target short message based on the user public key of the receiver to obtain and transmit the target encrypted short message, so that the safety of short message transmission is ensured; in addition, the user public key of the receiver is generated based on the identification information of the receiver and the preset public key base, the whole public key generation process is simple and convenient, the safety is high, and the safety of short message transmission is further ensured.
In the method for transmitting the non-peer short message, the software client in the sending terminal can directly generate the user public key of the receiving party based on the preset public key base and the identification information of the receiving party, which are acquired from the software server in advance, in the process of determining the user public key of the receiving party. That is, in the present application, the preset public key base may be provided by the software server, and correspondingly, the preset private key base may also be provided by the software server.
In a specific application scenario, before a software client in a sending terminal generates a user public key of a receiver based on a preset public key base and identification information of the receiver acquired from a software server in advance, whether the identification information of the software server and the preset public key base are stored can be judged; and if the identification information and the preset public key base of the software server are not stored, registering an account with the software server, and storing the identification information and the preset public key base of the software server after successful registration and login.
That is, in this embodiment, since the software client in the sending terminal needs to obtain the preset public key base from the software server, the software client in the sending terminal needs to perform information interaction with the software server, and in this process, the software client in the sending terminal needs to perform registration, login, and the like on the software server; the user public key of the receiver is generated by the identification information of the receiver and a preset public key base, so that the identification information of the receiver can be directly generated only after the identification information of the receiver is acquired, and in the process, a receiving terminal is not required to install a software client and carry out information interaction with a software server, so that the software client of the sender and the software client of the receiver are not equivalent. However, when the receiving terminal needs to decrypt the target encrypted short message, the receiving terminal needs to obtain the user private key of the corresponding receiving party, and the user private key of the receiving party is provided by the software server, so that the software client of the receiving terminal needs to perform information interaction with the software server in the process of decrypting the target encrypted short message, for example, the software client performs registration and login on the software server, and obtains the user private key generated by the software server for itself, and the like.
It should be understood that, in this embodiment, the software client generates the corresponding user public key based on the public key base acquired from the software server, and in some specific application scenarios, the software server may also directly generate the user public key and send the user public key to the software client for use, and the like, and the present application is not limited specifically herein. It should be noted that, for the user private key, in order to avoid security risk caused by leakage of the private key base, the software client may send the user identifier to the software server, and then the software server generates a corresponding user private key based on the user identifier and the private key base, and finally the software server sends the generated user private key to the software client for use, and so on.
Referring to fig. 2, fig. 2 is a second flowchart of a method for peer-to-peer message transmission according to an embodiment of the present disclosure.
The non-peer-to-peer short message transmission method provided by the embodiment of the application is applied to a software client in a receiving terminal, and can comprise the following steps:
step S201: and acquiring the target encrypted short message.
Step S202: and determining a user private key of a receiving party corresponding to the receiving terminal, wherein the user private key of the receiving party is generated based on the identification private key of the receiving party and the expanded private key of the receiving party, and the user private key of the receiving party is generated based on the identification information of the receiving party and a preset private key base.
In a specific application scenario, after acquiring a user private key of a receiving party, for example, after receiving the user private key of the receiving party generated by a software server, a software client in a receiving terminal may encrypt and store the user private key of the receiving party in advance, for example, an input target secret password may be received first, a key derivation algorithm is used to generate a target symmetric key based on the target secret password, the user private key of the receiving party is decrypted based on the target symmetric key to obtain and store the encrypted user private key of the receiving party, and accordingly, the input target secret password may be received in a process of determining the user private key of the receiving party corresponding to the receiving terminal; generating a target symmetric key based on the target key password through a key derivation algorithm; and decrypting the pre-encrypted user private key of the receiver based on the target symmetric key to obtain the user private key of the receiver. It is understood that when the secret password input by the user in the decryption stage is different from the secret password input in the encryption stage, the generated target symmetric key is different, so that the encrypted user private key of the receiver cannot be decrypted to obtain the user private key of the receiver, that is, the security of the user private key can be protected by means of the secret password.
In addition, in the process that the software client acquires the user private key from the software server, in order to protect the security of the user private key, the software client can generate a first symmetric key, encrypt the first symmetric key by using a system public key of the software server to obtain a first encryption key, and transmit the first encryption key to the software server; after receiving the first encryption key, the software server decrypts the first encryption key by using a system private key of the software server to obtain a first symmetric key, then encrypts a generated user private key by using the first symmetric key to obtain a private key encryption result and transmits the private key encryption result to the software client; the software client side decrypts the encrypted result of the private key by using the first symmetric key to obtain a corresponding user private key, so that the user private key is safely received from the software server.
In a specific application scenario, under the condition that a software client in a receiving terminal needs to acquire a user private key of a receiving party from a software server, the software client needs to establish connection with the software server, so that whether identification information of the software server is stored can be judged before determining the user private key of the receiving party corresponding to the receiving terminal; if the identification information of the software server is not stored, account registration is carried out on the software server, and after the registration is successful and login is carried out, the identification information of the software server is stored; sending the identification information of the receiver to a software server; and receiving and storing a user private key of the receiving party, which is generated based on the identification information of the receiving party and sent by the software server.
Step S203: and decrypting the target encrypted short message based on the user private key of the receiver to obtain the target short message.
