The anti-diversity concept for secure communication on a two-link compound channel provides secure communication over two parallel communication channels. The message is split into two separate bit sequences by a source splitter. An error correction encoder (110) is applied to the two bit sequences to provide two code words for two channels (122, 124), such that left and right halves of an error correction code matrix respectively corresponds to the two parallel signal channels (122, 124). For the left half of the error correction code matrix, an upper left matrix block is a random permutation matrix, an upper right block is the identity matrix, and the bottom right matrix block is a random matrix of column and row weight greater than or equal to one. The bottom left matrix block is a column permutation of the bottom right, random matrix block. The right half error correction code matrix is a similar, symmetric structure.
