随着移动的应用的不断增多和云计算的普及，将这两种技术结合起来的移动的云计算（MCC）近年来受到了广泛关注。然而，由于与安全和隐私相关的风险，MCC中的移动性安全保护已成为一个重要问题。本文提出了一种基于MCC的可追踪访问控制方案KD-TABE。首先，我们提出了一个可追溯的CP-ABE系统，并实现了密钥委托而不丢失可追溯性。其次，提出了一种新的重加密方法，它是基于一种直观的方法，支持任何单调的访问树，而不是重加密密钥。最后，为了减少对权威机构的信任，我们将权威机构分为三个部分，每个权威机构负责生成密钥的不同组成部分。分析表明，该方案能够满足MCC的安全需求。此外，与其他流行的型号相比，它的成本更低。
With the increasing number of mobile applications and the popularity of cloud computing, the combination of these two techniques that named mobile cloud computing (MCC) attracts great attention in recent years. However, due to the risks associated with security and privacy, mobility security protection in MCC has become an important issue. In this paper, we propose an efficient traceable access control scheme with reliable key delegation named KD-TABE in MCC. Firstly, we present a traceable CP-ABE system and realize key delegation without loss of traceability. Secondly, a new type of re-encryption method is proposed, which is based on an intuitive method that supports any monotonic access tree instead of the re-encryption key. Lastly, to reduce trust on authority, we separate the authority into three parts, and each authority is responsible for generating different components of the key. The analysis shows that the proposed scheme can meet the security requirement of MCC. In addition, it cost less compared with the other popular models.
