Network security protocol with cryptography and RFID system

Wireless communication is very common and widely applicable technique in communication field. In these field new techniques invented that is called RFID technique, in which object having RFID tags on them are being accessed in radio frequency region. Cryptography (method involves the both process “encryption” and “decryption”) is widely used in network system’s security. It is also the ancient method of encoding the original messages for transmission.On the other side The RFID technology recently has gained enormous attention in various field like in database maintenances(in the library management system), media, industry and as well as in network security. In the Radio frequency identification (RFID) use of an object (typically referred to as RFID tag) applied to or incorporated into a product, animal, or person (user) for the purpose of identification and tracking using radio waves. Each member has its unique id or RFID tag. However security and privacy pose significant challenges on the system.This paper will describe about the brief introduction of the old and dynamic method employed for network security that is cryptography. Cryptographic technique is widely applicable in network security field but still we are suffering from hacking and unauthorized access. Hence we have introduced a new idea for being applicable in security field that is RFID technique. Here we will describe its various applications in various fields and how it can be implemented in network security. The security and privacy issues of RFID and their solutions will also be discussed. And the future possible ideas for the new technologies will also be discussed.
