摘　　要：针对移动互联网海量移动终端用户的可信接入问题提出了一种芯片加密的可信接入系统的设计方案。首先将移动终端的可信接入过程划分为硬件预处理和可信接入两个子系统;在硬件预处理部分将有限状态机的思想用于模逆运算电路控制子系统的状态描述;而在可信接入部分基于Verilog语言将模拟运算电路抽象为控制系统状态转移图,再运用Verilog语言中的always模块将其转换为Moore型有限状态机,同时采用寄存器同步稳定输出控制信号,有效地实现了移动互联网终端设备的可信接入问题。仿真实验表明文中方法不仅能实现控制信号的输出与状态同步,还能避免组合输出产生的延迟及竞争与冒险现象,使终端设备的接入过程更加高效、稳定和可靠。Aimed at how to access about mobile terminal device in the mobile Intemet environment, a novel design scheme based on modular inversion circuits is presented. The trusted terminal control system includes hardware preprocessing sub-system and trusted access sub-system. FSM （finite state machine） is used in control sub-system design of modular inversion circuits. State transition diagram is created according to the function of modular inversion circuit, and it is converted into Moore FSM by three-always in Verilog language, control signals are steadily output by SYN register, accomPlish control sequencing and state transition of modular inversion circuit. The simulation experiment shows that the method not only can realize the control signal output and state synchronization, still can avoid the delay and the phenomenon of competition and adventure produced by combination output, make terminal access process is more highly ef ficient, stable and reliable.
