Authentication Schemes

Existing security authentication schemes are mostly concentrated on the key management and cryptographic algorithms. However, there are few authentication schemes designed according to the application needs. To solve this problem, considering the limited resource of wireless sensor networks and the practical application, a partially distributed authentication scheme is proposed. We use hierarchical network structure. Centralized authentication is used between the base station and cluster head nodes, while cluster head node and ordinary nodes use a distributed authentication. Analysis shows that this method has some advantages in the overhead of the storage, computing and communication, while network security can be guaranteed.

Broadcast Authentication

In Wireless Sensor Networks, Broadcast communication is the most fundamental and prevailing communication pattern. Securing the broadcast messages from the adversary is critical issue. To defend the WSNs against the adversary attacks of impersonation of a broadcast source or receiver, modification/fabrication of the broadcast message, attacker injecting malicious traffic to deplete the energy from the sensors, broadcast authentication of source and receivers becomes extremely inevitable. In this paper, we propose a novel ECC based public key distribution protocol and broadcast authentication scheme. The proposed method provides high security and has low overhead.
