The wireless body area networks (WBANs) is a practical application model of Internet of things. It can be used in many scenarios, especially for e-healthcare. The medical data of patients is collected by sensors and transmitted using wireless communication techniques. Different users can access the patient's data with different privileges. Access control is a crucial problem in WBANs. In this paper, we design a new security mechanism named combined public-key scheme in the case of attribute-based (CP-ABES) to address the user access control in WBANs. Our scheme combines encryption and digital signatures. It uses ciphertext-policy attribute-based encryption to achieve data confidentially, access control, and ciphertext-policy attribute-based signature to realize the identity authentication. The access policy used in our scheme is threshold. Based on this feature, the length of ciphertext and signature of our scheme is constant. Our scheme provides confidentiality, unforgeability, signer privacy and collusion resistance. We prove the efficiency of our scheme theoretically and analyze the security level and energy consumption of our scheme.
