The invention discloses a gateway access control method based on a fuzzy analytic hierarchy process and an entropy weight method. The method comprises the following steps: establishing an equipment credibility index system according to related parameter indexes when equipment accesses a gateway; performing calculation on the equipment access related data to obtain a dimensionless basic index value; calculating the subjective weight of each index through a fuzzy analytic hierarchy process; calculating the objective weight of each index through an entropy weight method; constructing an optimization model by adopting a least square method through a Lagrange multiplier and the total trust value of the access in combination with the subjective weight and the objective weight, and finally calculating to obtain the comprehensive weight of each basic index; and calculating an overall credibility evaluation value of the access of the equipment by using the comprehensive weight and the dimensionless basic index; and ge
