In an unprotected environment of wireless sensor network, the authentication scheme for multicast secure communication has to be designed with limited usage of resources and computation. In Multicast Authentication based on Batch Signature-Enhanced (MABS-E) scheme, a tree construction to counteract the Denial of Service (DoS) attack requires latency at the sender. This authentication latency leads to the jitter effect on real-time applications at the receiver. In few applications, user mobility is considered for authentication process. And also, due to user mobility, the sensor node is compromised.
