The invention provides a 0.7-order hybrid and chained fractional integral switching method and circuit. A hybrid 0.7-order fractional integral and a 0.7-order chained fractional integral are selectively controlled and output by use of a one-out-of-two analogue switch; when the control signal of the analogue switch is at a high level, the hybrid 0.7-order fractional integral is selected and output, and when the control signal of the analogue switch is at a low level, the chained fractional integral is selected and output; or when the control signal of the analogue switch is at the low level, the hybrid 0.7-order fractional integral is selected and output, and when the control signal of the analogue switch is at the high level, the chained fractional integral is selected and output. According to the 0.7-order hybrid and chained fractional integral switching method and circuit, the one-out-of-two analogue switch is adopted to realize automatic switching of a 0.7-order hybrid fractional integral circuit and a 0.7-order chained fractional integral circuit, and therefore, when the 0.7-order fractional integral circuits are applied to secret communication, the complexity of the 0.7-order fractional integrals is improved and the difficulty of deciphering is increased, which are advantageous for the security of communications.
