Abstract

A kind of method of data transfer encryption, belongs to encryption technology field, is realized by following steps：Server receives and detects the login message from client, includes user name, password, timestamp and the RSA public keys of client；Server dynamic generation DEA DES keys, and encrypted with the RSA public keys from client dynamic generation for the DES keys, generate rsa encryption ciphertext；Client decrypts the rsa encryption ciphertext received, obtains the DES keys；Client empties RSA key pair；The message encryption after compression is handled using the message transmitted between RLE compression algorithm server and client sides, and with the DES keys；The message received is decrypted with the DES keys for client/server, and the message after decryption is decompressed with RLE algorithms.The AES that the present invention is provided compresses certain types of data in ciphering process using compression algorithm, and compression efficiency and performance are preferably improved.

Description

A kind of method of data transfer encryption
Technical field
The present invention relates to encryption technology field, and in particular to a kind of method of data transfer encryption.
Background technology
With the high speed development of computer communication technology, increasing important information can select to carry out by network How transmission, therefore, ensure that the security that communication data is transmitted in a network has become the network that people pay close attention to One of safety problem, and become the core research point of network security to be encrypted as the information security technology of means.
The content of the invention
It is an object of the invention to provide a kind of method of data transfer encryption.
To realize the purpose of the present invention, the technical solution adopted in the present invention is：
A kind of method of data transfer encryption, comprises the following steps：（1）Server receives and detects the login report from client Text, includes user name, password, timestamp and the RSA public keys of client；（2）Server dynamic generation DEA DES is close Key, and encrypted with the RSA public keys from client dynamic generation for the DES keys, generate rsa encryption ciphertext；（3）Client Hold and decrypt the rsa encryption ciphertext received, obtain the DES keys；（4）Client empties RSA key pair；（5）Profit With the message transmitted between RLE compression algorithm server and client sides, and with the DES keys to the message encryption after compression at Reason；（6）The message received is decrypted with the DES keys for client/server, and with RLE algorithms to decryption after Message is decompressed.
The step（1）Concrete methods of realizing be：Server receives and detects the user name from client, password, Timestamp and RSA public keys；When correct and timestamp is denoted as current time to username and password, then step is performed（2）.
The AES that the present invention is provided compresses certain types of data, compression effect in ciphering process using compression algorithm Rate and performance are preferably improved.
Embodiment
The following implementation to the present invention is further described, so that those skilled in the art can be better understood from simultaneously Implement.
Embodiment 1
A kind of method of data transfer encryption, comprises the following steps：（1）Server receives and detects the login report from client Text, includes user name, password, timestamp and the RSA public keys of client；（2）Server dynamic generation DEA DES is close Key, and encrypted with the RSA public keys from client dynamic generation for the DES keys, generate rsa encryption ciphertext；（3）Client Hold and decrypt the rsa encryption ciphertext received, obtain the DES keys；（4）Client empties RSA key pair；（5）Profit With the message transmitted between RLE compression algorithm server and client sides, and with the DES keys to the message encryption after compression at Reason；（6）The message received is decrypted with the DES keys for client/server, and with RLE algorithms to decryption after Message is decompressed.
Described above is only embodiments of the present invention, it is noted that come for those skilled in the art Say, without departing from the technical principles of the invention, some improvement and modification can also be made, these improvement and modification also should It is considered as protection scope of the present invention.
