Wireless sensor networks are usually installed in a rough environments. Sometimes when the traditional network fails to deploy on that environments. The nodes in the network collect data and information from its environment. These data are moves from one node to another. All the data are not publicly accessible, some of them contain confidential and valuable information which only be accessible through a proper secure mechanism between two communicating parties. A secure authentication scheme can solve this problem to access the confidential data and protect the unauthorized access. In this research paper, we propose a secure sensor node authentication protocol. The protocol uses an identity-based signature (IBS) algorithm where Elliptic Curve Cryptography (ECC) based the digital signature algorithm (DSA) is used to generate a signature on a message and verify a signature on the message within the network. The successful authentication process in this protocol consists a new node registration, node authentication and finally a session key establish between two parties that make their future communication secure. In the WSN, the sensor nodes are installed in a place where the intruder may easily get access on the node. So a compromised node revocation also an important issue which is handled in this protocol. To provide the proper security metric, the protocol also analyzed through some conventional security solutions. The protocol ensures the confidentiality and the integrity of the data, provides improved communicational and computational performance and also achieves the energy efficiency due to the usage of more efficient ECC based DSA algorithm than RSA.
