Abstract:This project is designed to improve the security of the Military network. In this project the position of missile navigates as per the user’s requirement. This is done by entering the position, an angle of missile and giving directions in forward/ reverse, left/ right directions of missile onto user interface. The user sends the co-ordinates through PC based server on the base station. For security purpose encryption is done with RC4 algorithm. The microcontroller reads the encoded frame and decodes the frame by applying the RC4 decoding algorithm. The RC4 algorithm can encrypt and decrypt the information in many kinds of memorizers, such as SD cards.

Keywords: RC4; VNC; GOT; AES;

Navigation is a field of study that focuses on the process of monitoring and controlling the movement of a craft or vehicle from one place to another. All navigational techniques involve locating the navigator's position compared to known locations or patterns. Guidance systems are divided into different categories according to what type of target they are designed for - either fixed targets or moving targets. The weapons can be divided into two broad categories, Go-Onto-Target (GOT) and Go-Onto-Location-in-Space (GOLIS) guidance systems. A GOT missile can target either a moving or fixed target, whereas a GOLIS weapon is limited to a stationary or near-stationary target.

Navigation is a field of study that focuses on the process of monitoring and controlling the movement of a craft or vehicle from one place to another. Navigation is very important in defence system. The field of navigation includes four general categories: land navigation, marine navigation, aeronautic navigation, and space navigation .All navigational techniques involve locating the navigator's position compared to known locations or patterns. Guidance systems are divided into different categories according to what type of target they are designed for - either fixed targets o-r moving targets. The weapons can be divided into two broad categories, Go-Onto-Target (GOT) and Go-Onto-Location-in-Space (GOLIS) guidance systems. A GOT missile can target either a moving or fixed target, whereas a GOLIS weapon is limited to a stationary or near-stationary target. The trajectory that a missile takes while attacking a moving target is dependent upon the movement of the target. Also, a moving target can be an immediate threat to the sender of the missile. The target needs to be eliminated in a timely fashion in order to preserve the integrity of the sender. In GOLIS systems the problem is simpler because the target is not moving.

GOT Systems:

In every GOT system there are three subsystems:  Target tracker

 Missile tracker

 Guidance computer

The main application of the project is to navigate the Missile position to the user’s requirement. The user sends the co-ordinates through PC based server on the base station. At base station PC send these coordinates through memory devices to the field station. After the connection has been made the user first has to enter the Password. Then the user can enter the co-ordinate of Missile Navigation. After enter the X and Y co-co-ordinates the user can send the codes to the Missile unit. After receiving the co-ordinates the field, then compares the coordinates to the on board DC motor. It drives the DC motors of the tires of buggy until the received co-ordinates and the received co-ordinates match. After which the buggy indicate the linear coordinates sent by user. In this way the missile can be navigated to destination.

Cryptography plays very important role in security system it keeps any data Confidential between sender and receiver so no one can hack this data easily. Encryption is done with the use of an encryption key. This encryption key specifies how the message is to be encoded. An authorized party is able to decode the cipher text using a decryption algorithm, which usually requires a secret decryption key that adversaries do not have access to. The main factors in RC4’s success over such wide range applications are its speed and simplicity which efficiently implemented in both software and hardware. RC4 is fast, and it is applicable in real time processing.

 Enter the Linear direction of Tank (Forward ,Reverse, Right, Left)

 Encrypt the Data using RC4 algorithm

MEMORY DEVICES PC

 Frame: 256 Bytes

 Key: 4 Bytes

 XOR the data with the Encrypted Frame to get Encrypted Data)

 Create a Log.txt file in Pen drive. Store the data on Pen drive using USB interface in Log. txt.

Decoder Unit:

 Read the Encrypted frame from Log.txt file in pen drive using VNC1 IC.

 The frame has to be searched in the pen drive. If found the µC will read the file from memory devices using DOS commands. The VNC1 IC is connected to µC via RS232.

 Store in µC RAM.

 Decrypt the RC4 frame using the same algorithm as mentioned above.

 ADVANTAGES OF SECURED MISSILE NAVIGATION

 Efficient way for radar and GPS navigation

 Less time delays

 Quick response time

 Fully automate system

 Robust system

 Low power requirement

 CONCLUSION

The goal of this paper is to form secured communication for missile navigation. In military application security of data is the most important factor. Here we have tried to illustrate a secured communication with the help of encryption method and VNC which is useful for interfacing of pen drive with which missile can be navigated as per the instructed directions. It is done by entering the position, an angle of missile and giving directions in forward/ reverse, left/ right directions of missile onto user interface.

 FUTURE SCOPE

 Future teams can develop some more advanced algorithms with sensors that can detect when there is an attack.

missile and artillery.

 We can launch this missile through Launchpad or silo.
