This paper studies the secure communication over Blackwell's binary multiplying channel (BMC) in the presence of an external eavesdropper, who has the same observation as the legitimate users. Based on the idea of Schalkwijk's coding scheme, we propose a secrecy coding scheme, aiming for both high efficiency (measured by the transmission sum-rate) and high secrecy (measured by the normalized equivocation...
The use of an error-correcting code is essential in communication systems where the channel is noisy. We present a new technique to reconstruct RM (Reed-Muller) codes from a noisy intercepted bit stream. RM codes have several decoding methods, including a method that uses the FHT (Fast Hadamard Transform). The FHT algorithm is composed of several butterfly operations. To verify whether or not a received...
