Accompanying drawing explanation
Fig. 1 is Data Encryption Transmission basic flow sheet.
Detailed description of the invention
Below in conjunction with concrete accompanying drawing, scheme of the invention is described in detail:
As it is shown in figure 1, acquisition terminal comprises the following steps to data center's transmission data in the present invention:
A. data are tentatively arranged by acquisition terminal according to Land Information host-host protocol；
B. preliminary arrangement data are encrypted by acquisition terminal according to AES；
C. the data after encryption are sent to data center by acquisition terminal；
D. data center receives data and deciphers；
E. data center carries out filtering acquisition valid data according to Land Information host-host protocol to solving ciphertext data.
In the present invention, Land Information host-host protocol is from creating non-common protocol, is stateless protocol based on TCP/IP, uses
First arrangement before data send and the data filtering after reception.Including logging request message and data message.
(1) acquisition terminal sends logging request message to data center, including user name, password:
$ILLTS,<user>,<password>*hh\r\n
$ILLTS,<result>*hh\r\n
Wherein $ ILLTS represents the information that is logged on or logging status information sent,<user>for user name,<password>
For password,<result>is that data center returns to login authentication result, and hh is check code, r n be new line knot
Bundle symbol；After data center receives acquisition terminal logging request, first verify that user and password in message, if checking is logical
Cross, then returning result<result>is true；Acquisition terminal system starts after receiving response message to send to data center
Land Information data stream.
(2) acquisition terminal system sends datagram to data center:
$ILPIN,<1>,<2>,……,<n-1>,<n>*hh\r\n
$ILBPI,<1>,<2>,……,<n-1>,<n>*hh\r\n
$ILBLI,<1>,<2>,……,<n-1>,<n>*hh\r\n
$ILPLI,<1>,<2>,……,<n-1>,<n>*hh\r\n
