There exists a need for sharing user health data, especially with institutes for research purposes, in a secure fashion. This is especially true in the case of a system that includes a third party storage service, such as cloud computing, which limits the control of the data owner. The use of encryption for secure data storage continues to evolve to meet the need for flexible and fine-grained access control. This evolution has led to the development of Attribute Based Encryption (ABE). The use of ABE to ensure the security and privacy of health data has been explored. This paper presents an ABE based framework which allows for the secure outsourcing of the more computationally intensive processes for data decryption to the cloud servers. This reduces the time needed for decryption to occur at the user end and reduces the amount of computational power needed by users to access data.
需要以安全的方式共享用户健康数据，尤其是与研究机构共享用于研究目的的数据。在包含第三方存储服务（如云计算）的系统中，情况尤其如此，因为这限制了数据所有者的控制权。用于安全数据存储的加密技术不断发展，以满足灵活且细粒度的访问控制需求。这种发展导致了基于属性的加密（ABE）的出现。人们已经探索了使用ABE来确保健康数据的安全性和隐私性。本文提出了一个基于ABE的框架，该框架允许将数据解密中计算量较大的过程安全地外包给云服务器。这减少了在用户端进行解密所需的时间，并减少了用户访问数据所需的计算能力。
