Prevent Jamming Attacks in Wireless Networks using Cryptographic Primitives
Gujula . Neha, Dhanekula Sai Kiran, Malla Reddy · 2014
Jamming is typically referred as an intentional interference attack which is left due to the open nature of u medium. Due to their nature, wireless sensor network are probably the category of wireless networks most vulnerable to radio channel jamming. This intentional interference with wireless transmission launch pad for mounting Denial-Of-Service attack on wireless networks. Adversaries with knowledge of protocol specification and network secrets can launch jamming attacks which are difficult to detect. The adversary targets the messages of high priority and huge information when he is active for short period of time. This real time packet classification is done at physical layer. To protect our text from jamming and also to prevent real time packet classification we combine cryptographic primitives with physical layer attributes. There are five schemes for preventing this packet classification. They are Real time packet classification, Strong Hiding Commitment Schemes (SHCS), Cryptographic Puzzles Hiding Schemes (CPHS, All-Or-Nothing Transformation Hiding Schemes (AONTSHS), Channel aware detection algorithm. For providing more secured packet transmission in wireless networks along with the three schemes we use the random key distribution.
