Abstract
From smart watch to remote healthcare system, wireless body sensor networks (WBSNs) play an important role in modern healthcare system. However, the weak capacity of devices has limited WBSNs development. Considering the huge processing and storage capacity of the cloud, it can be merged with WBSNs to make up for the deficiencies of weak capacity. Based on this consideration, the concept of cloud-assisted WBSNs has been proposed recently. In contrast to generic data, the data in cloud-assisted WBSNs will be used for providing medical diagnosis, so the integrity of data is very important because any modification will result in severe consequences such as misdiagnosis. The public auditing scheme could provide an efficient solution to check the data integrity remotely without downloading them. However, the traditional public auditing scheme for cloud cannot be used directly due to the high data density and weak processing capacity in WBSNs. So, in this paper, we proposed a lightweight and efficient public auditing scheme, LEPA, for cloud-assisted WBSNs. Compared with similar schemes, the WBSNs’ client only needs to do one symmetrical encryption with low computational cost in LEPA. Security proof shows that LEPA can resist two types of adversaries in random oracle model. The efficiency evaluation also shows that LEPA outperforms previous proposals.

With the technological advances in various fields, the people’s life expectancy increased all over the world
Based on the lightweight designing concept, we reduced the cryptographic operation of client in our protocol; besides, by transferring the authenticator generation work to service provider, the client (WBSNs devices) in our scheme only needs to do one symmetric encryption
Considering that there has been no good solution for public auditing in cloud-assisted wireless body sensor networks (WBSNs), we propose a lightweight and efficient public auditing scheme, LEPA, for cloud-assisted WBSNs in this paper
Summary
With the technological advances in various fields, the people’s life expectancy increased all over the world. It is noteworthy that the data stored in cloud-assisted WBSNs are the basis of all clinical diagnoses, so the integrity of storing data is a very important issue because any modification on data will result in severe consequences such as misdiagnosis To solve this problem, the public auditing technique is proposed. (2) We proposed a new public auditing scheme LEPA for cloud-assisted WBSNs. Based on the designing concept of lightweight cryptographic protocols, we reduced the operations with expensive time cost such as bilinear mapping and hash to point and improved the efficiency of the system; besides, we translated the tag generation work from client to service provider so as to reduce the computational burden on client kind.
