We propose four dimensions (4D) Hyper-Chen chaos to achieve a better security performance of physical-layer in Universal Filtered Multi-Carriers (UFMC) systems. Four dimensions are related to XOR operation, frequency domain chaotic constellation mapping and subcarriers scrambling respectively. In our proposed multifold encryption scheme, quadrature amplitude modulation 16 (QAM16) symbols are scrambled and distributed onto the noisy-like complex plane independently. An encrypted UFMC data transmission is successfully emulated demonstrated over wireless multipath channel. The proposed encryption scheme has key space of \(5. 2 5\times 10^{ 3 5 4}\) and can combat exhaustive attacks effectively.
