abstract = {This paper proposes the trinion Hartley Transform (THT) and presents its commonly used properties, such as linearity, cyclic shift property, convolution theorem, and so on. In addition, the relationship between THT and Fourier Transform is derived, and a fast computation for THT based on FFT is proposed. Finally, based on the proposed THT and its fast computation, encryption and decryption methods suitable for color images are proposed, and the effectiveness of the proposed methods are verified by simulation results.}
