Abstract
The invention provides a self-adapting data encrypting and decrypting method. A system comprises a data identification and configuration module, a DES (Data Encryption Standard) encrypting and decrypting module and an AES (Advanced Encryption Standard) encrypting and decrypting module. According to a regulated data transmission protocol, an encrypting and decrypting manner of data is identified through hardware, a control register is configured and an encrypting and decrypting algorithm meeting the protocol is gated. The encrypting and decrypting algorithm comprises a DES, a 3DES and an AES to meet different encrypting and decrypting requirements. According to the system disclosed by the invention, a data encrypting and decrypting manner can be identified in a self-adapting way according to a transmission protocol, so that the data transmission manner and the reliability are increased.
Description
Technical field
This patent relates to the communication security field, be specifically related to a kind of according to host-host protocol regulation, adaptive data encrypting and deciphering technology.
Background technology
The communication technology and development of internet technology are maked rapid progress, and all trades and professions all be unable to do without computer now.People are increasingly high for the security requirement of data in transmission course, so the information security technology important that seems.Encryption plays an important role as the strongest weapon in the information security.The DES algorithm is a kind of block encryption algorithm, carries out encryption and decryption with 64 grouped datas, and data encryption is conciliate the secret emissary with identical algorithm structure, and just the use of key order is different.3DES is a kind of pattern of des encryption algorithm, and it uses 3 64 key that data are encrypted 3 times.AES adopts symmetrical block cipher system, and the minimum support of key length is 128,192,256, and is stronger 1021 times than 56 keys of DES.
Though AES is better than the confidentiality of DES, also paid more hardware resource and encryption time simultaneously.
Summary of the invention
The method that the purpose of this invention is to provide a kind of adaptive data encrypting and deciphering.
The objective of the invention is to realize by following mode; System has comprised data identification configuration module, DES encryption and decryption module and AES encryption and decryption module; Data Transport Protocol according to the rules; Adaptive selection data encrypting and deciphering mode of operation; Comprise that des encryption, 3DES encrypt or AES encrypts, the data identification configuration module is analyzed all information that contain data encrypting and deciphering mode and encryption and decryption figure place in first byte in the data transmission procedure, and the information that remaining byte comprises according to first byte is placed among the buffer of required encryption and decryption module.
Concrete steps are following:
In the process of transfer of data; The data identification configuration module can dispose the needed pattern of encryption and decryption process according to the entrained information of first byte of transmission; Expressly, the length of ciphertext length and key; General's byte subsequently in the middle of the buffer of corresponding module, is carried out encryption and decryption to the transmission data, to the last EO according to the regular allocation of encryption and decryption at last then.
According to different encryption and decryption modes, DES, 3DES and AES encryption and decryption module all have the form of different separately plaintexts, ciphertext and key, accomplish the encryption and decryption of data at last through the different encryption and decryption cycles.
The invention has the beneficial effects as follows: DES and AES AES are merged, according to Data Transport Protocol, adaptive selection configuration data encryption and decryption mode.Also increased the alternative of communication mode when so not only having improved communication security.

Embodiment
Explanation at length below with reference to Figure of description method of the present invention being done.
System has comprised data identification configuration module, DES encryption and decryption module and AES encryption and decryption module; Data Transport Protocol according to the rules; Adaptive selection data encrypting and deciphering mode of operation; Comprise that des encryption, 3DES encrypt or AES encrypts, the data identification configuration module is analyzed all information that contain data encrypting and deciphering mode and encryption and decryption figure place in first byte in the data transmission procedure, and the information that remaining byte comprises according to first byte is placed among the buffer of required encryption and decryption module.Concrete steps are following:
In the process of transfer of data, the data identification configuration module can dispose the needed pattern of encryption and decryption process according to the entrained information of first byte of transmission, expressly, the length of ciphertext length and key.Byte that then will be subsequently according to the regular allocation of encryption and decryption in the middle of the buffer of corresponding module.At last the transmission data are carried out encryption and decryption, to the last EO.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
