Designing a chaotic system with a simple structure and complex dynamic behavior is one of the main tasks of chaotic cryptography. This paper designs a new 1D chaotic system called 1D two-parameters-sin-cos (1D-TPSC). Compared with high-dimensional chaotic systems. the 1D-TPSC has a simple structure and is easy to implement with software. https://trendingcustomes.shop/product-category/stainless-steel-tumbler-with-handle/
