In distribution energy systems (DESs), the information security plays an essential role. Real-time encryption techniques can guarantee the transmission rate and confidentiality simultaneously. We propose a novel real-time encryption algorithm for DESs. First, we construct a 13D chaotic system based on quaternion, Chua’s circuit and complex variables, and discuss the existence of the attractors and other chaotic characteristics. Secondly, based on the proposed complex chaotic system, a simple encryption algorithm is proposed to ensure the confidentiality of DESs. Finally, our algorithm is verified by the standard test image and monitoring pictures in DESs. The execution time of the proposed algorithm is 0.0035s and 0.0021s respectively. It is only one percent of other algorithms. At the same time, our other security performances are competitive with other algorithms. And it has the ability to resist the malicious attack and avoid unnecessary equipment shutdown in DESs.
