Deniable authentication is an important security aspect for achieving authentication and privacy. The goal is to allow an intended receiver to identify the origin of a given message without being able to prove sender's identity to a third party. In this paper, we propose a pairing-free identity based non-interactive deniable authentication (IB-NIDA) scheme whose security is based on the difficulty of solving elliptic curve computational Diffie-Hellman problem (ECDH). The proposed scheme undergoes a formal security analysis with random oracle model and standard symbolic model (AVISPA). In addition, the performance analysis shows that our proposed scheme achieves efficiency. Furthermore, such design is applicable for resource constrained mobile devices.
