4) unknown flag explanation:
The unknown data that server end sends over has two kinds, does not know its meaning at present, and client is changed to the 0x0000 value with it when sending data.
5) digital signature explanation:
All enciphered datas are placed 8 byte number word signatures at this.Its value is obtained through SHA computing and MD5 computing by RC4 session key assignments and performance data.
The connection procedure explanation:
1) client Connection Service device;
2) the ISO data Layer connects;
3) send the initiation protocol relevant information, receive encryption, decruption key;
4) tunnel application;
5) encrypted form sends FTP client FTP information, simultaneous verification cryptographic protocol;
6) platform software certification authentication;
7) each function connects, each performance data transmission.
5, performance data layer:
Performance data is that client and server carry out mutual authentic data.
Like this, use the RDP agreement, made up a virtual remote desktop server, allow the remote desktop client of standard to login this module.
RDP and RFB protocol-compliant module:
The effect of this module is that the RDP request with the remote desktop client converts the RFB agreement request to, and send to the RFB server, simultaneously, RFB protocol responses bag with the RFB server acknowledge, convert the RDP respond packet to, send to the remote desktop client, finish a complete agency by agreement process;
In this module, the realization of RDP is with reference to the RDP proxy module, and by research, it is as follows to understand RFB agreement fundamental norms:
The RFB agreement: be " thin passenger plane " agreement truly, the RFB design of protocol focus on reducing hsrdware requirements to client.Client just may operate on many different hardware like this, and it is simple that the task of client computer will be tried one's best on realizing.The RFB agreement is stateless for client.That is to say: if client disconnects from server end, if it reconnects identical server so, the state of client can be saved.Even a different client can be used for connecting identical RFB server.And can obtain the User Status identical with previous client in new client.What therefore, user's application interface became is very convenient.Need only suitable network and connect existence, the user just can use the application program of oneself so, and these application preservation always, even also can not change at different access points.So no matter at which, system all can provide familiar, a unique computing environment to the user.
Display protocol: display protocol is to be based upon on " pixel data being placed on one by x, in the square frame of y location " this single circular foundation.At first sight get on, it is unusual inefficient methodology that so many user's interface units are drawn out.But, allow different pixel data coded systems, make us flexibility significantly arranged in the different parameter (as: network bandwidth, the render speed of client, server process speed) of processing.Finish the renewal of frame buffer by the sequence of rectangle.Once upgrade representing being transformed into from an available frame buffer status that another is available, therefore a bit and the hardwood of video similar.Although the renewal of rectangle generally separates, be not necessary.The more new portion of display protocol passes through command driven by client.That is to say that renewal just takes place when the request of server end customer in response end.So just allow the protocol update quality be variable.Client/network is slow more, and renewal speed is also just slow more.Use for some, the renewal of same area is continuously.If with a slow client, the buffer status of frame buffer is can be uncared-for so.So also can reduce requirement to client network speed and render speed.
The input agreement: the input agreement is based on the connection protocol of equipment such as the keyboard at standard operation station and mouse.Incoming event is exactly to send to server end by the input client.These incoming events also can come comprehensive by off-gauge I/O equipment.For example, the writing pen engine may produce a KeyEvent.
Protocol message: the RFB agreement can be transmitted reliably, as byte stream or message based.The same with most of agreements, it also is by ICP/IP protocol bunch connection.Agreement is finished connection by three steps.At first be handshake message, purpose is that protocol version and cipher mode are held consultation.Second step was an Initial message, was mainly used in the initial message of client and server.Be exactly the mutual of normal protocol at last, client can send message as required, can obtain the answer of server then.All message begin with type of message, next are specific message data.The fundamental type that protocol message is described has: U8, U16, U32, S8, S16, S32.U represents signless integer, and S represents signed integer.All byte integer (except pixel value itself) are deferred to the Endian order.PIXEL represents a pixel value bytesPerPixel byte, 8XbytesPerPixel=bi t s-per-pixel, and this equation is in client/server, ServerIni t message (with reference to the 6.3.2 joint), SetPixelFormat message.

RDP and XDMCP protocol-compliant module:
The effect of this module is that the RDP request with the remote desktop client converts the XDMCP agreement request to, and send to the XDMCP server, simultaneously, XDMCP protocol responses bag with the XDMCP server acknowledge, convert the RDP respond packet to, send to the remote desktop client, finish a complete XDMCP agency by agreement process.
In this module, the realization of RDP is with reference to the RDP proxy module, and by research, it is as follows to understand XDMCP agreement fundamental norms:
The XDMCP agreement is used UDP 177 ports.When needs when the XDMCP server is initiated a session, this module need be sent Query bag to it.If the XDMCP server allows the visit of this module, it can return the Willing bag as replying to this module.(this module also can send BroadcastQuery or IndirectQuery and wrap and begin a session, and this mechanism is similar to uses DHCP to obtain the IP address.)
The XDMCP server will inevitably require to authenticate to this module.For accomplishing this point, this module sends Request and wraps the server to XDMCP, and the XDMCP server returns an Accept bag.If Accept has comprised the response of this module expectation, then the XDMCP server is by authentication.For instance, may need key of XDMCP server access for generating correct response.If authentication success, this module can send Manage and wrap and tell XDMCP server.Then, the XDMCP server can show login interface to this module that connects as the X client of a routine.
During session, this module can send the KeepAlive bag to the XDMCP server at interval.If the XDMCP server is not responded the Alive bag in a period of time, this module can suppose that the XDMCP server is out of service, and stops this connection.
The present invention can also have other execution mode, and the technical scheme that equal replacement of all employings or equivalent transformation form all drops within the scope of protection of present invention.
