摘要

•We propose an ITDCCML, which has better kinetic properties than CCML and TDCCML.•The positions and values of pixels are altered through DNA strand exchange.•According to Watson-Crick base pairing property, DNA strand diffusion is implemented as conditional diffusion, which can enhance the security of encryption algorithm effectively.
