Query: Secure Data Access for Wireless Body Sensor Networks   Recently, with the support of mobile cloud computing, a large number of
health related data collected from various body sensor networks can be managed
efficiently. However, to ensure data security and data privacy in
cloud-integrated body sensor networks is an important and challenging issue. In
this paper, we present a novel secure access control mechanism Mask Certificate
Attribute Based Encryption for cloud integrated body sensor networks. A
specific signature is designed to mask the plaintext, then the masked data can
be securely outsourced to cloud severs. An authorization certificate composing
of the signature and related privilege items is constructed that is used to
grant privileges to data receivers. To ensure security, a unique value is
chosen to mask the certificate for each data receiver. The analysis shows that
the proposed scheme has less computational cost and storage cost compared with
other popular models.
