Design and Implementation of Hybrid Broadcast Authentication Protocols in Wireless Sensor Networks

The proposed broadcast authentication protocols for wireless sensor networks can be divided into two categories: protocols based on digital signature and protocols based on improved message authentication code. This paper implements and evaluates the performance of two broadcast authentication: TinyECC, which is based on ECDSA, and GBA, which is based on improved MAC. Through analysis of the performance difference of the two protocols, this paper proposes a hybrid broadcast authentication protocol (HBA). HBA achieves an appropriate compromise of security and performance according to packet value. The analysis and experiments show that HBA is efficient and practical.
