Access control is a critical security service in sensor networks. Sensor networks provide the query service of the environmental monitoring data as the service provider to the users. The current access control scheme based on public key cryptography is high in expenses, and difficult to resist replay and DoS attacks. This paper proposes several effective access control schemes using the one-way key chain and the Merkle hash tree. Also this paper provides a revocation tree scheme to revoke the… CONTINUE READING
