Chapter3 3 3. Confidentiality and Integrity for IoT/Mobile Networks

Abstract This chapter discusses how to ensure confidentiality and integrity for data flow in IoT applications. While confidentiality could be assessed by access control, cryptography, or information flow analysis, integrity is still an open challenge. This chapter proposes to use error-correcting codes to guarantee integrity, i.e., to maintain and assure the errorless state of data. Besides errors, many communication channels also cause erasures, i.e., the receiver cannot decide which symbol the received waveform represents. The chapter proposes a method that might correct both errors and erasures together. Our method is efficient in reducing memory storage as well as decoding complexity.
