This paper proposes a key management protocol based on transitory initial key in wireless sensor networks to solve the security problems in Pairwise communications,Local broadcast communications and Authentication of the newly joined sensor nodes in such networks,PLA for short.When deploying a wireless sensor network,each node is assigned a unique identifier and a transitory initial key.Each node computes a pairwise key,a local broadcast key and an authentication key based on the transitory initial key and some related information.Theoretical analysis shows that the proposed PLA protocol is more secure and more energy efficient than existing protocols such as LEAP and OTMK.
