摘　　要：电子健康档案云存储成为研究热点,但云端存储节点的不可控特性使得其存储数据的安全性得不到保障,从而制约了电子健康档案云存储的进一步发展。利用RS纠删码编码将文件信息割裂并分片存储来防止局部存储节点数据块泄露导致的整个文件信息被窃取,利用其纠删能力实现损坏数据的恢复,为电子健康档案云存储数据安全性保障提供了一种新的解决方案。Cloud storage has become highlight in the electronic health records.Due to the uncontrollable characteristics of cloud storage,security of electronic health records data stored in the cloud storage node could not be ensured.Hence,its further application is limited.In this paper,the technique of RS erasure encoding is introduced to prevent the whole electronic health records being stolen when the data in local cloud storage nodes leaked,through splitting the whole information and storing them in fragments.Meanwhile,the RS erasure code is used to recover the damaged data of electronic health records and provide a new data security protection in cloud storage of electronic health records.
