Signal method with the open key which designates the group of the braid as subject. According to this invention, the fact that it is utilized with the aforementioned method, the braid T which is converted from braid S with the secret key which is stipulated by the expression sign s where specified braid S in braid group G is chosen and, especially, operator T (S) the open key and two braids which are stipulated with expression sign v being equal, in other words, at least is operation of the one time which verifies the equivalent characteristic of the expression sign of that kind of two braids. It is applied to the signal method with the open key whose effective speed is fast.
