Abstract-Non-malleability is an important property in commitment schemes. It can resist to the person-in-the-middle (PIM) attacks within the interaction. In this paper, we focus on the non-malleability in ID-based trapdoor commitments. We first give two constructions of (full) ID-based trapdoor commitment schemes based on RSA and Factoring assumptions respectively and then extend them to non-malleable schemes. The formal proofs show that our proposed schemes satisfy all the desired security properties.
