“…Hadamard codes, which are generated using Hadamard matrices, are of the type 2 n , n + 1, 2 n+1 , which means bitstreams of length n + 1 are mapped to codewords of length 2 n and the whole code consists of a total number of 2 n+1 codewords. Further details about Hadamard codes can be found in [2]. A randomly chosen codeword of a Hardamard code is XORed with the cryptographic key where both bitstreams are of the same length.…”
