Wireless Communication Security Through Symbol Obfuscation in Physical Layer

Secure communication is a critical and challenging issue in wireless networks. To achieve the information theoretic secrecy the leading approach is artificial noisy symbol. The basic idea in this paper is enhancing the security in wireless communication. Multiple Inter-symbol Obfuscation(MIO) method will be deployed in the physical layer. MIO is a method for transferring the data and it provides security in wireless network. The possibility of symbol obfuscation is to eliminate the eavesdropper participation and the fake packet injection. The original data symbols are obfuscated by using set of symbol keys. The information theoretic secrecy will be achieved and the other hand an eavesdropper cannot able to decrypt the original data symbols. The legitimate receiver can easily check the original data symbols and reject the fake packet injection during the data transmission.
