Recently, Wireless Body Area Networks (WBANs) have been an attractive platform for pervasive computing and communication. Since the patient-related data is significance for medical diagnosis and patients' health-care, the security of distributed data storage is critical need for applications. However, the distributed architecture makes it challenging to build a secure and efficient data storage system due to the resource-constrained nature of sensor node. Besides, due to the lack of physical protection, WBANs are vulnerable to attacks when deployed in hostile environments. In order to address the challenges, we propose a novel secure and efficient data storage scheme with dynamic integrity checking in this paper. Based on the policies of multiple secret sharing, we first propose a secure and efficient patient-related data storage and access scheme for WBANs. Furthermore, to dynamically check the integrity of the distributed data shares, we then propose an efficient data integrity verification scheme based on orthonormal vectors. Finally, the security and performance analysis shows that the proposed scheme is secure and practical for WBANs.
