Abstract: A computer-implemented method for error-correction-encoding and encrypting of a file is provided. The file is split into at least two blocks. The first block is encrypted using a given encryption key. The encrypted first block is encoded twice using a first and second forward error correction code of the first block. Each subsequent block is encrypted by performing an algebraic operation. The encrypted block is encoded twice using a first and second forward error correction code for this block, wherein a cryptographic indexing function provides a set of indices used by the second forward error correction code to produce the second encoded chunk. The first encoded chunks of each encrypted block are outputted. The computer-implemented method enables secure transmission of a file content between low power devices.
