摘　　要：As an emerging technology,cloud-assisted wireless body area networks(WBANs)provide more convenient services to users.Recently,many remote data auditing protocols have been proposed to ensure the data integrity and authenticity when data owners outsourced their data to the cloud.However,most of them cannot check data integrity periodically according to the pay-as-you-go business model.These protocols also need high tag generation computation overhead,which brings a heavy burden for data owners.Therefore,we construct a lightweight remote data auditing protocol to overcome all above drawbacks.Our work can be deployed in the public environment without secret channels.It makes use of certificate-based cryptography which gets rid of certificate management problems,key escrow problems,and secret channels.The security analysis illustrates that the proposed protocol is secure.Moreover,the performance evaluation implies that our work is available in cutting down computation and communication overheads.
