文摘

Wireless body area network (WBAN) has emerged as one of the most promising technologies for e-healthcare. In recent years, cloud-assisted WBANs have attracted intensive attention from the academic and industrial communities. How to ensure data confidentiality, integrity, non-repudiation, and access control is an important and challenging issue for widespread deployment of cloud-assisted WBANs. In this paper, we introduce a new cryptographic primitive named key-policy attribute/identity-based signcryption (KP-AIBSC) scheme to address above challenge problem, which can fulfill the functionality of identity-based signature and key-policy attribute-based encryption in a logical step. We first give formal syntax and formulate security model of KP-AIBSC scheme. Next, we present a concrete KP-AIBSC construction from bilinear pairings. The proposed construction is proved to be indistinguishable against adaptive chosen plaintext attacks under the DBDH assumption and existentially unforgeable against adaptive chosen message and identity attacks under the CDH assumption in the random oracle model. Finally, we exhibit an efficient fine-grained cryptographic access framework for cloud-assisted WBANs by exploiting our proposed KP-AIBSC scheme.
