We present a scheme based on the Blom scheme for resisting the Sybil type attacks. In this
scheme, the authority pre-distributes the combination of the secret used in the Blom scheme. The
attacker needs to compromise the specified number of nodes to compromise the whole systems.
Furthermore, our scheme which provides a stronger relationship between ID and key would make
authentication more reliable and resistant against the Sybil attacks.
