Wireless body area networks (WBANs) are an emerging technology for the real-time monitoring of physiological signals. WBANs provide a mechanism for collecting, storing, and transmitting physiological data to healthcare providers. However, the open wireless channel and limited resources of sensors bring security challenges. To ensure physiological data security, this paper provides an efficient Certificateless Public Key Infrastructure Heterogeneous Ring Signcryption (CP-HRSC) scheme, in which sensors are in a certificateless cryptosystem (CLC) environment, and the server is in a public key infrastructure (PKI) environment. CLC could solve the limitations of key escrow in identity-based cryptography (IBC) and certificate management for public keys in PKI. While PKI is suited for the server because it is widely used on the Internet. Furthermore, this paper designs a ring signcryption method that allows the controller to anonymously encrypt physiological data on behalf of a set of sensors, but the server does not exactly know who the sensor is. The construction of this paper can achieve anonymity, confidentiality, authentication, non-repudiation, and integrity in a logically single step. Under the computational Diffie-Hellman (CDH) problem, the formal security proof is provided in the random oracle model (ROM). This paper demonstrates that this scheme has indistinguishability against adaptive chosen ciphertext attacks (IND-CCA2) and existential unforgeability against adaptive chosen message attacks (EUF-CMA). In terms of computational cost and energy usage, a comprehensive performance analysis demonstrates that the proposed scheme is the most effective. Compared to the three existing schemes, the computational cost of this paper’s scheme is reduced by about 49.5%, 4.1%, and 8.4%, and the energy usage of our scheme is reduced by about 49.4%, 3.7%, and 14.2%, respectively.
