%X In this paper,a commitment scheme against selective decommitment attacking was named as a selective decommitment scheme which was composition of general bit commitment schemes. In the secure two party computation-model,we proposed a new definition for selective decommitment scheme which was shown equivalent to the original one. Another main result was composition of bit equivocable commitment scheme satisfied with our new definition and could be composed to a secure selective decommitment scheme.
