Abstract: Considering code-based cryptography, quasi-cyclic low-density parity-check (QC-LDPC) codes are foreseen as one of the few solutions to design post-quantum cryptosystems. The bit-flipping ...
Abstract: The performance of a code under the maximum-likelihood (ML) decoder highly depends on the weight enumerating function (WEF). However, how to compute efficiently the WEF of a polar code or a ...
