Abstract:
The role of cryptograph is important for data
security. Many cryptographic techniques can be used to keep
security of sensitive data. Information is an arm of Military as
well as the security of information is it’s life. In addition, this
paper is preferred to protect information from physical theft and
hacking of enemies and intruders. This paper will be developed
the data security system for a local network using symmetric key
encryption and message digest. It is reliably applied Military’s
Monthly Commissioned Reporting System (MMCRS) and other
paper-based System in the Military network by using file
Encryption and Decryption techniques. The system will provide
a symmetric-key algorithm, AES(secure hash algorithm) is also
used to ensure the authenticity of message. Key Distribution
Center (KDC) is used for secret key sharing between sender
and receiver.
