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.

In the description of the present invention, it is to be understood that the terms "opening," "upper," "lower," "thickness," "top," "middle," "length," "inner," "peripheral," and the like are used in an orientation or positional relationship that is merely for convenience in describing and simplifying the description, and do not indicate or imply that the referenced component or element must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be considered as limiting the present invention.

A data processing method for DNA calculation, comprising the steps of:

step 1: exporting the data of the DNA computer to an electronic computer, and decoding the data into data readable by the electronic computer;

step 2: dividing the data obtained in the step 1 into N sections of data segments; the encryptor generates N-1 random data segments to be inserted into two adjacent data segments, and the encryptor outputs the random data segments to the decryptor;

and step 3: according to the sensitivity and the importance preset by the user, the data segments are encrypted in a segmented manner, and a decryptor generates a secret key which is stored in the electronic computer;

and 4, step 4: and integrating a plurality of data segments into one data segment.

Further, in the step 3, the user selects the data segment which does not need to be encrypted and the invalid data segment according to the sensitivity and the importance degree preset by the user, abandons the encryption of the data segment which does not need to be encrypted, and deletes the invalid data segment.

Further, in the step 3, a corresponding key is generated by the key generator, corresponding key information is calculated according to the importance level degree, the data type and the number of the information, and the data is encrypted to obtain a data ciphertext; and the user side extracts the asymmetric public key corresponding to the database server of the received user data from the key database, and encrypts and transmits the key index information and the data ciphertext by an asymmetric encryption algorithm.

More specifically, a corresponding key is generated by a key generator, corresponding key information is calculated according to the importance level degree, the data type and the number of the information, and the data is encrypted to obtain a data ciphertext. And the user side extracts the asymmetric public key corresponding to the database server of the received user data from the key database, and encrypts and transmits the key index information and the data ciphertext by an asymmetric encryption algorithm. The main station receives the transmitted encrypted data, transmits the encrypted data to the terminal through the main station, screens the information of the transmission terminal again, and discards the screened invalid information or the information which is not encrypted reasonably. When the data is decrypted, the asymmetric decryption key is used for decrypting the symmetric key index, then the key is restored by using the key derivation algorithm, and then the symmetric key is used for decrypting the data packet to obtain the data original text. In the process of data encryption, decryption and transmission, user data with relatively large data volume is encrypted and decrypted by using a symmetric algorithm, and simultaneously, asymmetric encryption and decryption operation is performed on key index information with relatively small data volume, so that the problems of security, difficult key management and the like caused by only adopting the symmetric encryption algorithm can be effectively solved, and the problems of low operation efficiency and the like caused by data encryption by the asymmetric encryption algorithm are solved.

After acquiring an encryption request of a user for data, determining an encryption range of the data based on the encryption request. The encryption range of the data is determined by the user instead of encrypting all the data, so that the load of computer hardware is reduced, and the data encryption speed is increased. The user sends feedback information through the user side to determine that the encryption range of the data is correct, and then the hash value of the feedback information is generated by using a hash algorithm, wherein the hash algorithm has an irreversible characteristic, namely the feedback information cannot be obtained although the hash value of the feedback information is known. The security of data encryption is ensured; then, matching an encryption algorithm from a preset encryption algorithm library for the data block in the encryption range according to the hash value; and the encryption range data block is encrypted according to the matched encryption algorithm, so that the security of data encryption is further ensured, and the risk of data leakage on the data storage cloud platform is reduced.

In some examples of the present invention, before performing step 3, the sequence is randomly scrambled to generate an encryption mapping table, where the encryption mapping table records an original arrangement position, a data type, and a data size of each data block.

Further, the data segments which do not need to be encrypted are randomly disorderly and sequentially combined and transmitted to the data storage cloud platform for storage.
