摘　　要：文章针对可公开发布的组合文档(Publicly Posted Composite Documents,PPCD)在用户设定的有效期后的安全删除问题,将基于身份加密系统(Identity-Based Encryption,IBE)、云存储系统(Cloud Storage System,CSS)、随机对称加密密钥以及对象存储系统(Object Storage System,OSS)进行结合,同时引入分安全等级思想,提出基于身份加密的组合文档安全删除方案(ICDSS);通过对该方案的综合性分析,证明方案的安全性和可行性。A composite document(Publicly Posted Composite Documents)for public release PPCD the issue of secure deletion after the expiration date set by the user,an identity encryption system(Identity-Based Encryption)is used in this article IBE,cloud storage system(Cloud Storage System);and CSS,random symmetric encryption keys and object storage systems(Object Storage System);and OSS)combination,meanwhile,introduction of security hierarchy,a secure deletion scheme of composite documents based on identity encryption is proposed(ICDSS).Then,Through a comprehensive analysis of the programme,to prove the safety and feasibility of the scheme.
