Current key management schemes only consider the security of newly deployed nodes in wireless sensor networks, whereas the security of mobile nodes is ignored. In order to ensure data transfer secure in node mobility scenarios, we propose a composite security mechanism based on the elliptic curve digital signature algorithm to help nodes in the mobile scenarios to authenticate their identities and establish the pairwise keys. Analysis shows that this scheme is very low in storage, computation, and communication overhead.
