Abstract: In current scenario we present our approach regarding the implementation of new wireless security shaped with noisy symbols, using a software-development driven approach. Communication security is critical and increasingly challenging issue in wireless networks. We propose a multiple inter-symbol obfuscation (MIO) scheme, which utilizes a set of artificial noisy symbols (symbols key) to obfuscate the original data symbols in the physical layer. MIO can effectively enhance the wireless communications security. On the one hand, an eavesdropper, without knowing the artificial noisy symbols, cannot correctly decrypt the obfuscated symbols from the Eavesdropped packets. On the other hand, a legitimate receiver can easily check the integrity of the symbols key and then reject the fake packets from the received packets. The security analysis reveals that, without considering the initial key, the MIO scheme can achieve information-theoretic secrecy against the passive eavesdropping attack and computational secrecy against the fake packet injection attack.
Keywords: artificial noisy symbols (symbols key), Multiple inter-symbol obfuscation (MIO).
