As a fundamental requirement for providing security in sensor networks,key management plays an essential role in authentication and encryption.A new hybrid key-management scheme for wireless sensor networks is proposed.Base on the Blom matrix and chaos,this scheme can pre-load some key information to sensors to insure the establishment of secure link.The analysis shows that the scheme can cost lesser key storage overhead and delete and update key information with the network topology changes to avoid key information to be revealed.
