Abstract Chaotic systems play an indispensable role in the fields of cryptography and information security. Sine-Transform-Based Chaotic System (STBCS) can address the shortcomings of low complexity and limited chaotic behaviour of classical chaos systems. In this paper, a compact hardware STBCS is proposed and developed on the FPGA device by using the Stochastic Computation (SC) technique. The traditional arithmetic operations are replaced by the SC and finite state machines design. The structure of STBCS is opti…
