SECURE TRANSMISSION WITH ERROR CORRECTING CODE

摘要

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 (54) at least one first value (P₁) into several encrypted values and integrating at least one combination (P₁,_j) of said encrypted values to compute (55) at least one part (P₂... P_n-k) of said parity symbols.
