Abstract
The invention belongs to character encryption and decryption technology field, a kind of Chinese character encipher-decipher method is disclosed, Chinese character string to be encrypted is subjected to unicode codings first；The Chinese character string after the coding is encrypted followed by AES, encrypted characters string is generated；The encrypted characters string is decrypted using AES after carrying out the transmission of data to the encrypted characters string, generation decryption character string；The decryption character string is finally subjected to unicode transcodings, the Chinese character string before being encrypted；The mess code rate in encryption process can be effectively reduced using the method, making the security of data transfer increases.
Description
Technical field
The present invention relates to a kind of encipher-decipher method, particularly a kind of Chinese character encipher-decipher method, for Chinese character
It is encrypted.
Background technology
Data transfer is at every moment all occurring, and its security needs to be guaranteed, and character string is entered frequently with AES at present
Row encryption.AES is as the Advanced Encryption Standard in cryptography, and also known as Advanced Encryption Standard Rijndael enciphered methods are U.S.'s connection
A kind of block encryption standard that government of nation uses.This standard is used for substituting original DES, has been analyzed in many ways and widely complete
The world is used.By the selection flow of 5 years, Advanced Encryption Standard by National Institute of Standards and Technology (NIST) in
It is published on FIPS PUB 197 on November 26th, 2001, and turns into effective standard on May 26th, 2002.It is 2006, senior
Encryption standard already turns into one of most popular algorithm in symmetric key encryption.
Due to the diversity and complexity of Chinese character, when carrying out encryption and decryption to Chinese character using AES, often occur
Mess code, this is totally unfavorable for the transmission of data.
The content of the invention
Based on above technical problem, the invention provides a kind of Chinese character encipher-decipher method, so as to solve existing AES
The technical problem of mess code can be produced when carrying out encryption and decryption to Chinese character.
The technical solution adopted by the present invention is as follows：
A kind of Chinese character encipher-decipher method, comprises the following steps：
Step 1：Chinese character string to be encrypted is subjected to unicode codings；
Step 2：The Chinese character string after the coding is encrypted using AES, encrypted characters string is generated；
Step 3：The transmission of data is carried out to the encrypted characters string；
Step 4：The encrypted characters string is decrypted using AES, generation decryption character string；
Step 5：The decryption character string is subjected to unicode transcodings, the Chinese character string before being encrypted.
Further, in the step 1, the Chinese character in Chinese character string to be encrypted is taken out, by each Chinese character
Corresponding unicode codes are changed into respectively.
Further, in the step 2, Chinese character string after coding is utilized to be divided into some Plaintext blocks by described, according to
AES Advanced Encryption Standards create scrambler, and the Plaintext block is encrypted using the scrambler, generate encrypted characters string.
Further, in the step 4, the encrypted characters string is divided into some ciphertext blocks, according to AES superencipherments
The ciphertext blocks are decrypted by rule creation scrambler using the scrambler, generation decryption character string.
Further, in the step 5, the decryption character string is divided into multiple unicode codes by Li Yong u marks,
The unicode codes are converted into corresponding Chinese character, each Chinese character is combined to the Chinese to be formed after decryption
Character string.
In summary, by adopting the above-described technical solution, the beneficial effects of the invention are as follows：
Chinese character can be converted into unique code by Unicode codings, recycle AES to carry out encryption and decryption, can be effective
The mistake for preventing the generation of mess code in encryption and decryption, reducing data transfer.
Brief description of the drawings
Fig. 1 is the flow chart of the present invention.
Embodiment
All features disclosed in this specification, can be with any in addition to mutually exclusive feature and/or step
Mode is combined.
The present invention is elaborated below in conjunction with the accompanying drawings.
A kind of Chinese character encipher-decipher method, comprises the following steps：
Step 1：Chinese character string to be encrypted is subjected to unicode codings, the Chinese in Chinese character string to be encrypted is taken out
Character, corresponding unicode codes are changed into by each Chinese character respectively.
Step 2：The Chinese character string after the coding is encrypted using AES, encrypted characters string is generated；
Utilize Chinese character string after coding to be divided into some Plaintext blocks by described, create close according to AES Advanced Encryption Standards
Code device, the Plaintext block is encrypted using the scrambler, generates encrypted characters string.
Step 3：The transmission of data is carried out to the encrypted characters string；
Step 4：The encrypted characters string is decrypted using AES, generation decryption character string；
The encrypted characters string is divided into some ciphertext blocks, according to AES superencipherment rule creation scramblers, institute is utilized
State scrambler the ciphertext blocks are decrypted, generation decryption character string.
Step 5：The decryption character string is subjected to unicode transcodings, the Chinese character string before being encrypted.
The decryption character string is divided into multiple unicode codes by Li Yong u marks, by the unicode code conversions
Into corresponding Chinese character, each Chinese character is combined to the Chinese character string to be formed after decryption.
After the Chinese character string is encrypted using AES, the transmission of data is carried out using encrypted characters string.
It is embodiments of the invention as described above.The present invention is not limited to the above-described embodiments, anyone should learn that
The structure change made under the enlightenment of the present invention, the technical schemes that are same or similar to the present invention each fall within this
Within the protection domain of invention.
