The paper presents an idea of providing a high degree of security against crypto attack in the switchable data-dependent operations (SDDOs). SDDOs is a cryptographic primitive focused on the development of ciphers appropriate for applications in limited environments. SDDO architecture is based on the block transform binary data based on the substitution-permutation networks with a control binary vector. The new design of the SDDOs is proposed using bent functions. Bent functions provide maximum non-linearity of functions and system resistance to cryptanalysis. Using a new SDDOs can be constructed the new block ciphers.
