The invention concerns a method and a system for encoding digital data (DATA) represented by source symbols, with an error correcting code generating parity symbols from, for each parity symbol, a plurality of source symbols and at least one parity symbol of preceding rank, including at least encrypting once () at least one first value (P) into several encrypted values and integrating at least one combination (P) of said encrypted values to compute () at least one part (P. . . P) of said parity symbols.

Secure transmission with error correcting code

A method and a system for coding digital data represented by source symbols (Si) with an error-correction code. The error-correction code generates parity symbols (Pj) based on, for each parity symbol, several source symbols and at least one parity symbol of preceding rank. At least a part of the source symbols is submitted to at least a first ciphering. The obtained ciphered symbols and the rest of the unciphered source symbols are submitted to the error-correction code.
