As a result of modern progress, the usage of wireless sensor networks (WSNs) in the medical field has gotten considerable interest. WSNs are implemented to gather and transmit patient physiological data in healthcare management systems. Therefore, authentication and patient data privacy are two major challenges in the healthcare system. Thus, some cryptographic mechanisms are applied to secure the transmission of physiological data collected by the wearable sensors using bilinear pairing. However, the bilinear pairing is considered high computational. This paper provides a practical and efficient certificateless signcryption scheme with free pairing to secure communication between the sensors and the remote control system. Also, signcryption is employed to meet the main security requirements such as confidentiality, non-repudiation, integrity, and authentication. Besides, under the Computational Diffie-hellman assumption and the Discrete logarithm problem in the random oracle model, this protocol is shown to meet unforgeability and confidentiality. Finally, as shown in the security analysis, our protocol is secure and practical.
