The existing instant messagingtechnology does not provide built-in support for security feature as proposed idea. And also in Battle FieldManagement System the most commonly used as means of communication is Walky-Talky, which we feel is muchunsecured. In this paper we propose a secured instant messaging system using identity-based cryptosystems whichprovide a strong authentication and secured communication for both IM client to IM server and IM client to IMclient. Identity-based cryptography is a type of public-key cryptography in which a publicly known stringrepresenting an individual or organization is used as public key.

IM worms and securecommunication are two safety issues of instantmessaging system. Most of the existing systemgive more scalability priority than that of securityservice. Instant messaging communication can bedone in following manner IM client to IM serverand IM client to IM client with the followingproperties of security areas: andconfidentiality. There are some existing IMsystems that only provide confidentiality service,for instance Kikuchi et al. some uses TLS/SSL toestablish a secure connection employing digitalcertificate. However it increases the privacyconcerns. And certificate management is complexand costly. In this paper we propose identity-Basedcryptosystem, a secure instant messaging systemfor Battle field Management system, which canprovide strong authentication and securecommunication for both instant messaging clientto instant messaging server and instant messagingclient to instant messaging client. Mostly usedcommunication for Battle field Management is thatof Walky-Talky which we prove it as moreunsecure. Propose a secure IM system by usingidentity-based cryptosystems. The system consistsof a group of private key generators (PKGs), whichgenerate the master key according to securedistributed key generation protocol to avoidkey agreement problem. In propose an identitybased cryptosystems, the public key of an entitycan be easily calculated from his identityinformation (e.g. e-mail address, IP address, IMaccount, etc.),and private key is generated by atrusted third party named as private key generator(PKG),which is transferred via a secure channelfrom the PKG to the client.1.2 Identity-Based CryptosystemIdentity-Based Cryptosystem is variouscryptography combinations of keys used bycryptographic group of community. Identity-basedcryptography is a type of public-key cryptographyin which a publicly known string representing anindividual or organization is used as public key.The public key string can be IP address, domainname or email address. Identity-Based systemallows any party to generate a public key from aknown identity value. Trusted third party, calledprivate key generator (PKG) generates the privatekey. To operate the PKG first publish a master keyand retain the master private key. A user submitshis identity ID to the PKG. The PKG computes theIJSER 2014http://www.ijser.org

Once the privatedecryption key from the PKG, the receiver uses ittogether with the element r p and bilinear map tocompute the secret message key, which is thenused to decrypt the original senders’ message.1.2.3 Identity-Based signatureIdentity-based signature depends on theassumption that secret keys are secured absolutely.If a secret key is exposed, secret key have to bereissued. Thus limiting the impact key exposure ofsecret key in Identity-Based signature is animportant task.1597secure and confidentiality proposed DeffieHellman protocol suitable for Instant Messagingsystem. Identity-Based public key cryptography(cryptosystem) was proposed which was firstintroduced by Shamir.In an identity-based cryptosystems, thepublic key of an entity can be easily computedfrom his identity information for e.g. e-mailaddress, IP address, IM account, etc., and thecorresponding private key is generated by a trustedthird party named as private key generator (PKG),the private key is transferred from the PKG to theuser through a secure channel. The system consistsof a group of private key generators (PKGs), whichgenerate the master key according to securedistributed key generation protocol to avoid keyescrow problem. IM service provider functions asa registration authority, answers for authenticatinguser information and signing authenticated users’information to PKGs.2.4 Advantage of Proposed SystemThe Main advantages of using theproposed IM system are as follows:i). Gives more priority on security than scalability.ii).IM system support security features likeIntegrity, Authentication, Non-repudiation andConfidentiality etc. by using Identity-BasedCryptosystem.iii). Generation of private key on request is verysecure.iv). In an identity-based cryptosystems, the publickey of an entity can be easily computed from hisidentity information for e.g. IP address, domainname or email address.IJSERII SYSTEM ANALYSIS2.1 Existing SystemThe existing IM technology does notprovide built-in support security features. Most ofthe existing IM services were design givingscalability priority over security. Some IMemploys TSL/SSL to establish a secure connectionbetween client and a server by digital certificate.However TLS/SSL will increase privacy concern.Some only provide confidentiality service e.g.Kikuchi. And in Battle field management systemmost commonly used is walky-Talky, which wefeel is very unsecure.2.2 Disadvantage of Existing SystemThere are various disadvantages in theexisting. Some of them are as follows:i) Giving more scalability priority over security.ii) There is no built in support (like confidentiality,integrity, authentication and non-repudiation).2.3 Proposed SystemWe propose a secure IM system by usingIdentity-Based Cryptosystem, which can providestrong authentication and secure communicationfor both IM client to IM client and IM client to IMserver. Secure communications includes theProperties of: Authentication, Integrity, NonRepudiation, Integrity and confidentiality.

International Journal of Scientific & Engineering Research, Volume 5, Issue 6, June-2014ISSN 2229-55181599participants in our secure IM model: IM clients,IM Server, PKGs.IM server is in charge givingauthentication to all users of the system and willallow only those users to use its resource. The IMserver keeps track of the status for instance onlineand off-line from computer of each user and storessufficient information about them to allow anotheruser to set up a peer-to-peer communicationchannel with them. IM server at the serviceprovider’s end know that the user is online andready to receive messages, and the current status ofeach of their contacts is also downloaded to hisclient.The IM client is a user that can use tosend message. Its basic function is to log in the IMserver and send message and manage contact list.When a user wishes to send a message to anotheruser, IM client first contacts the IM server toobtain the IP address of the user and the port onwhich he is listening for incoming messages. TheIM client then initiates a TCP connection to thatclient and sends the secure message by usingidentity-based cryptosystems. Once the one-to-onecommunication channel between users has beenestablished, the IM server plays no further part butjust to inform the IM clients of updates to thestatus of their contacts.The PKGs generate the master key. IMservice provider functions as a registrationauthority, answers for authenticating userinformation and signing authenticated users’information to PKGs. User can get his private keycorresponding to his IM account by performing ablind key issuing protocol with any PKGs.Finally, secure connection between IM client andIM client, IM client and IM Server, which can beproposed using identity-based encryption scheme,identity-based signature scheme, identity-basedsigncryption or identity-based authenticated keyagreement scheme. A user, with an identity IDperforms required steps to get his private keyaccording to anonymous key issuing protocol foridentity-based cryptosystems. The password isuser’s chosen password during authentication andthe tuple i.e ID,password is stored in IM serviceprovider database corresponding to his public key.User can obtain his private key from PKG by typehis ID and password at client side.5.2.1 Authentication ModuleUser will be permitted to give theusername and password in the login page. If theuser name and password is correct means user willallow to accessed the application. If the user nameand password is not valid, user will not allowaccessing the application.A user with valid user ID which IMservice provider provides will be able to access theservice and perform various chat according tohis/her preference.5.2 Module DescriptionIn software, a module is a part ofprograms. Programs are composed of one or moreindependently developed modules that are notcombined until the linked in program. A modulecan contain one or several routines. In hardware, amodule is a self-contained component.5.2.4 IM Text ModuleAfter successfully login to the Textmodule, the use of life Text chat can start. It willdisplay user mood in the chat. Sending textmessages and receiving is performed in thismodule.

However IM which has veryless usage in Battle Field Management System.Most of these existing instant messaging serviceswere designed giving scalability priority oversecurity. We proposed a secured instant messagingsystem by using identity-based Cryptosystem,which can further provides secured strongauthentication and secured communication forboth instant messaging. The proposed instantmessaging for usage in Battle Field Managementsystem will help secured the communication to alarge extent rather the used of Walky-Talky.VIII FUTURE ENHANCEMENTFuture is the stage of the project when thetheoretical design is turned out into a systemworking principal. And also further the applicationcan be integrated with features like the combatvehicles sensors and detectors.
