In this note, we show that a proposed secure broadcasting scheme is insecure. We also present a modified scheme to overcome this weakness. The modified scheme has the extra adva...
Due to limited energy capacity of batteries, the function lifetime of sensor networks in general is longer than the operational lifetime of single nodes. Therefore, to keep the ne...
Group management service plays a key role in wireless sensor networks (WSNs) as it provides support to high level middleware services such as object tracking, security, fault-tole...
—Multicasting has not been widely adopted until now, due to lack of access control over the group members. The Authentication, Authorization and Accounting (AAA) protocols are be...
Many existing pairwise key establishment in sensor networks were developed based on the polynomial-based method. However, this method cannot offer the basic authentication function...
