Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, a heterogeneous encryption transmission method provided by the present invention includes the steps of:
s1, receiving a data synchronization request to form synchronization data;
specifically, one of the two pieces of information-interactive terminal equipment initiates a data synchronization request, and acquires synchronization data from the terminal initiating data synchronization according to the data synchronization request.
It is understood that the synchronization data includes field definition information and data field information, wherein the field definition information includes a field name, a field type and a field number, and the data field information includes a value of a field of the field definition information. For example, the field name is "dept", the field type is "1101", the number of fields is "4", and the field value of the field definition information is "unit code".
S2, compressing the synchronous data, encrypting the synchronous data by using a symmetric encryption technology to produce a key and adding an identity information label;
specifically, after the obtained synchronous data is compressed, a key is randomly generated by using a symmetric encryption technology and is used for encrypting the file, and then a public key in an asymmetric encryption algorithm is used for encrypting the encryption key. For example, after data compression, an AES symmetric encryption key is randomly generated, and the key is used for encrypting a file to be encrypted. Each encryption randomly generates a key, so that the keys are different every time, and the reliability of encryption is improved. A pair of public key and private key is generated by using RSA algorithm, public key file is published to network, private key is reserved for use and can not be transmitted, and generated random key is encrypted by using public key. And storing the file encrypted by the generated AES symmetric encryption key and the key content encrypted by the public key into the same file. The encrypted key occupies a fixed number of bytes and is stored at the head of the file, and the encrypted ciphertext is stored after the encrypted key to form a final encrypted file.
After the final encrypted file is formed, a unique identity tag is added to the final encrypted file, and the identity tag can be any identifier, such as an image or other identifier with unique identification, such as a fingerprint, a voiceprint, and the like.
S3, synchronizing the compressed encrypted file to the terminal, and performing identity tag authentication and file decryption on the encrypted file;
specifically, after the encryption process is completed, the compressed encrypted file is synchronized to the terminal device, the terminal device performs identity tag authentication on the received encrypted file, decrypts the file after the authentication is successful, and does not decrypt the file when the authentication is unsuccessful.
In this embodiment, after the identity standard authentication is successful, the encrypted file is first split, a fixed number of bytes is first read as an encrypted key portion, the remaining portion is a ciphertext portion, and then the ciphertext portion is decrypted using a private key.
S4, decompressing to form a plaintext file after the label is successfully authenticated and decrypted;
specifically, after the file is decrypted successfully, the decrypted file is decompressed to form a plaintext file, so that the transmission of file encryption is completed.
Referring to fig. 2, step S1 further includes the sub-steps of:
s11, initiating a synchronous data request;
specifically, one of the two terminals establishing information interaction initiates a synchronous data request.
S12, acquiring synchronous data;
specifically, after a synchronous data request is initiated, synchronous data is acquired.
Referring to fig. 3, step S2 further includes the sub-steps of:
s21, compressing the synchronous data;
specifically, the acquired synchronization data is compressed.
S22, encrypting the compressed file;
specifically, an AES symmetric encryption key is randomly generated, and the key is used to encrypt a file to be encrypted. Each encryption randomly generates a key, so that the keys are different every time, and the reliability of encryption is improved. A pair of public key and private key is generated by using RSA algorithm, public key file is published to network, private key is reserved for use and can not be transmitted, and generated random key is encrypted by using public key. And storing the file encrypted by the generated AES symmetric encryption key and the key content encrypted by the public key into the same file. The encrypted key occupies a fixed number of bytes and is stored at the head of the file, and the encrypted ciphertext is stored after the encrypted key to form a final encrypted file.
S23, adding an identity label to the encrypted file;
specifically, after encryption is completed, an identity tag is added to the encrypted file.
Referring to fig. 4, step S3 further includes the sub-steps of:
s31, transmitting the compressed and encrypted file to the terminal;
specifically, after the above steps are completed, the file which is compressed and encrypted and to which the identity tag is added is transmitted to another terminal.
S32, the terminal verifies the identity label;
specifically, the terminal verifies the identity information on the encrypted file after receiving the transmitted file.
S33, decrypting the encrypted file;
specifically, after the identity tag passes the verification, the encrypted file is decrypted.
Referring to fig. 5, step S33 further includes the sub-steps of:
s331, segmenting the encrypted file;
specifically, after the identity tag is successfully verified, the encrypted file is divided into a fixed byte number part and other parts.
S332, reading the fixed byte number as the encrypted key part;
specifically, the fixed byte number part is used as the key part.
S333, decrypting the ciphertext part by using a private key;
specifically, the private key is used for decrypting the other parts except the fixed byte number.
