Cryptography Based Method for Preventing Jamming Attacks In Wireless Network

Nowadays, wireless networks became more affordable. As a consequence of this, they're being deployed virtually all over in numerous forms, starting from cellular networks to sensor and wireless local area networks. As these networks are gaining popularity, providing security and trustiness is additionally changing into a key issue. We address the problem of selective jamming attacks in wireless networks. In these attacks, the attacker selectively targets specific packets of “high� importance by exploiting his knowledge on the implementation details of network protocols at varied layers of the protocol stack. We have a tendency to illustrate the impact of selective jamming on the network performance by illustrating varied selective attacks against the TCP protocol. We have a tendency to show that such attacks may be launched by performing real-time packet classification at the physical layer. We examine combination of cryptographic primitives with physical layer attributes for preventing real-time packet classification and neutralizing inside knowledge of the attacker.
