The invention relates to an iterative method by message passing for decoding of an error correction code that can be displayed in a bipartite graph comprising a plurality of variable nodes and a plurality of check nodes. For each iteration in a plurality of decoding iterations of said method: variable nodes or check nodes are classified (720) as a function of the corresponding degrees of reliability of decoding information available in the neighbourhoods (Vn(d),Vm(d)) of these nodes, a node with a high degree of reliability being classified before a node with a low degree of reliability; each node thus classified (725) passes at least one message (alphamn,betamn) to an adjacent node, in the order defined by said classification. The invention also relates to a computer program designed to implement said decoding method.
