Embodiment Construction
[0044] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.
[0045] Such as figure 1 As shown, this embodiment describes a lightweight batch audit method for cloud storage medical big data oriented to wireless body area network, including:
[0046] S1. Audit system initialization: the audit system generates a public-private key pair of the elliptic curve signature algorithm, a lightweight symmetric encryption algorithm and its symmetric key, a hash function, and a lightweight pseudonym for constructing homomorphic message authentication codes. Random number generators and pseudo-random functions, as well as outsourced multiple-sum algorithms for elliptic-curve collections of precomputed data. The elliptic curve signature algorithm is a linear homomorphic aggregation signature algorithm.

The present invention discloses a cloud storage medical big data light-weight batch audit method facing a wireless body area network. The method comprises: initialization of an audit system; generation of medical big data signature; generation of medical data audit certificate; and medical big data audit certificate verification. A medical big data file is compressed to message authentication codes, the elliptic curve signature algorithm is employed to perform digital signature of the message authentication codes of medical data, the medical big data file is subjected to light-weight stream password encryption, and finally, signature and cryptograph of the medical data are stored into a cloud server based on the wireless body area network. The cloud storage medical big data light-weight batch audit method facing a wireless body area network ensures confidentiality of cloud user medical big data, is helpful for medical cloud users to authorize a third-party auditor to perform batch audit of a medical big data file and effectively detects whether cloud medical data is tampered or not so as to avoid doctors' clinic misdiagnosis.
Description
technical field [0001] The invention relates to the technical field of network space security, in particular to a lightweight batch audit method for cloud storage medical big data oriented to wireless body area networks. Background technique [0002] Today, the leapfrog development of human beings in electronic sensor technology and wireless communication technology has made wireless sensor networks widely used in various fields such as medical health and sanitation, environmental monitoring, military investigation and industrial engineering control, which contains broad commercial prospects. and research value. Therefore, wireless sensor networks have received more and more attention and investment from academia and industry. As an important application of wireless sensor network, wireless body area network has also received corresponding attention. First of all, wireless body area network (WBAN) is a miniaturized electronic device composed of a series of low-power, light...
