A confidential sort system comprises first to Mth apparatuses. The first to Mth apparatuses obtain inverse substitution [[σ0−1]] of L-bit stable sort of {→k0}. The first to Mth apparatuses perform, on i=1, . . . , N−1, a process of converting [[σi-1−1]] to hybrid substitution to obtain {σi-1−1}, a process of inversely substituting {→ki} with {σi-1−1} to obtain {σi-1→ki}, a process of obtaining inverse substitution [[σ′i−1]] of L-bit stable sort of [[σi-1→ki]], a process of synthesizing {σi-1−1} with [[σ′i−1]] to obtain [[σi−1]]:=[[σi-1−1σ′i−1]], and a process of converting [[σN-1−1]] to hybrid substitution to obtain {σN-1−1}.
