Web Desk Authentication (Synopsis)

WEB DESK AUTHENTICATION
ABSTRACT
The Project –WEB DESK is a remote display system which
allows you to view a computing ‘destop! environment" #t also now to $e
White Board %pplication"
&'( Server wors according to the client –server architecture"
To connect to a &'( server) you need to give the machine name" (lient
can then connect to the server" *nce clients are connected to the server
machine this user can see everything you do)just lie i+ his machine was
woring alone"
NOTE:
,sing -.B Protocol data transmission should $e done"
This Project has some $asic modules lie/
• Socet #mplementation
• %uthentication
• (lient and Server #nitiali0ation
• .rame Bu++er ,pdate
Socket Implementation:
#n this module client server architecture using socets"
(onnection oriented 1T(P2 implementation
Authentication:
This module completely depends upon the server" #+ server as
+or authentication client should provide authentication 1password2 through
D3DES algorithm"
Client and Se!e Initiali"ation:
The module deals with #nitiali0ation o+ client machine and server
machine"
#ame Bu$$e Update:
This module is main part o+ the application" (lient is going to
receive pi4el values and server in+ormation then client should paint on the
screen"
R#B %ROTOCO&:
-.B 1-emote .rame Bu++er2 protocol ena$les remote users to
share the destop o+ the server either e4clusively or on a sharing $asis"
-.B 15remote +rame $u++er62 is a simple protocol +or remote access to
graphical user inter+aces" Because it wors at the +rame $u++er level it is
applica$le to all windowing systems systems and applications) including
788) Windows 3"89:;9'T and <acintosh"
The remote endpoint where the user sits 1i"e" the display plus
ey$oard and9or pointer2 is called the &irtual Pad" The endpoint where
changes to the +rame $u++er originate 1i"e" the windowing system and
applications2 is nown as the -.B server"
&irtual Pad truly a 5thin client6 protocol" The emphasis in the
design o+ the -.B protocol is to mae very +ew re=uirements o+ the client"
#n this way) clients can run on the widest range o+ hardware) and the tas
o+ implementing a client is made as simple as possi$le"
%ROB&E' S%ESI#ICATION:
A. Existing System and their Limitations:
*ne must now what the pro$lem is $e+ore it can $e solved"
The $asis +or a candidate system is recognition o+ the need +or improving
communication" Be+ore solving a pro$lem prepare a statement) a
statement speci+ying scope and o$jectives o+ the pro$lem"
#n the present scenario o+ distri$uting in+ormation using a (lient
– Server environment there e4ist communication mechanisms such as
TE>'ET etc" These are only character $ased in nature and do not provide
an easy way +or 5communication across networ6" %lso the communication
may not always $e plat+orm independent"
B. Proposed System
The limitations that are discussed under the e4isting system can
$e countered $y adapting a -.B Protocol) which is easy to handle
communication" By using the -.B Protocol we can support ?,#@$ased
client@server interaction and allows multiple clients to share the destop o+
the server"
The -.B 1-emote .rame Bu++er2 protocol was proposed $y
Tristan -ichardson and Kenneth -" Wood ) *-> )(am$ridge in Aanuary
8::B"
The protocol is $ased around a single graphics primitive/ “put a
rectangle of pixel data at a given x, y position”"
The -.B relies on sending encoded pi4els to the client that
contains the in+ormation o+ the Server Destop" The client then decodes
the pi4els and draws them on a graphical application running on its
machine" Events occurring at the client side are trapped and sent to the
Server where the changes are re+lected"
.or this purpose the -.B protocol suggests the use o+ a .rame
Bu++er" The .rame Bu++er actually contains the destop in+ormation which is
updated when the client generates an event" This updated $u++er must $e
sent to the Server which updates its own destop accordingly" Similarly
when the Server generates events that a++ect the destop) the updated
$u++er is redrawn at the (lient" This provides a synchroni0ed destop
sharing +acility"
%ROB&E' ANA&(SIS
The $asic aim o+ the pro$lem analysis is to o$tain a clear
understanding client@server interaction and allows multiple clients to share
the destop o+ the server" %nalysis leads to the actual speci+ication" .irst
tas is to prepare a statement speci+ying the scope and o$jective and the
pro$lem"
%ccording to the present system the pro$lem is character@$ased
communication across networ" This type o+ communication is not
su++icient to the present woring environment"
