We present a combination of a free propagation scheme and a classical 4f encrypting architecture to design a technique to simultaneously encrypt multiple input objects. To our knowledge, this is the first reported technique for multiplexing encrypted data in one-step. Unlike existing multiplexing methods, encryption can be performed without setup modiffcations. A brief mathematical description and digital simulations support our proposal.
