Abstract :
This paper presents a dynamic fuzzy commitment scheme. In the scheme, multiple commitments are stored and one of them is replaced in each successful authentication. The process of calculation of the new commitment and the replacement is explained in three variants of the scheme. The adjacency matrix is applied to some variants of the scheme to increase their efficiencies.
