摘要: 云存储安全一直是云安全研究的重点。Ghao等提出了一种云存储可信共享(TSCS)方案,但分析发现,该方 案不能抵抗恶意CSP攻击。根据云存储安全需求,构建了云存储可信共享模型。随后,依据云存储可信共享模型构 造了一个云存储可信共享方案。分析表明,新方案减弱了对随机数的依赖,不仅具有Zhao等的TSCS方案的安全性 能,还能抵御服务器端的恶意墓改。新"I'SCS方案具有一定的应用前景。

Abstract: Cloud storage security has always been emphasis in cloud security. Zhao et al. proposed a `I'SCS(Trusted Sha- ring over Cloud Storage) scheme, which is incapable of withstanding malicious CSP attacks, according to our analysis. This paper constructed the model of TSCS in terms of its requirements for security. Afterwards, a new TSCS scheme was proposed based on it, Analysis shows the new one relies less on random numbers,and not only retains the security properties of Zhao et al. 's scheme, but also resists tampering of the server, and could be put into application.
Key words: Cloud security, Cloud storage security, Trusted sharing
