Abstract
A code generation apparatus () generates a plurality of spreading code sequences, using block encryption processing of outputting a plurality of blocks as a spreading code sequence (D). A parameter selection unit () acquires a sequence parameter (KP) uniquely corresponding to each spreading code sequence (D) of the of the plurality of spreading code sequences. A secret key acquisition unit () acquires a secret key (K). A code sequence generation unit () changes output data that is output from each of process elements, using the sequence parameter (KP), when the code sequence generation unit () generates each spreading code sequence (D) of the plurality of spreading code sequences by the block encryption processing using the sequence parameter (KP) and the secret key (K).
