In emergency care, fast and efficient treatment is vital. The availability of Electronic Medical Records (EMR) allows healthcare professionals to access a patient’s data promptly, which facilitates the decision-making process and saves time by not repeating medical procedures. Unfortunately, the complete EMR of a patient is often not available during an emergency situation to all treatment teams. Cloud services emerge as a promising solution to this problem by allowing ubiquitous access to information. However, EMR storage and sharing through clouds raise several concerns about security and privacy. To this end, we propose a protocol through which all treatment teams involved in the emergency care can securely decrypt relevant data from the patient’s EMR and add new information about the patient’s status. Furthermore, our protocol ensures that treatment teams will only access the patient’s EMR for the period during which the patient is under their care. Finally, we present a formal security analysis of our protocol and some initial experimental results.

一种基于基于密文策略的加密技术的碎玻璃协议，用于访问云中的病历

在紧急护理中，快速有效的治疗至关重要。电子病历（EMR）的可用性使医疗保健专业人员能够迅速访问患者的数据，从而简化了决策过程并通过不重复医疗程序节省了时间。不幸的是，在紧急情况下，所有治疗团队通常都无法获得患者的完整EMR。通过允许无所不在的信息访问，云服务作为解决此问题的有希望的解决方案而出现。但是，通过云进行的EMR存储和共享引发了对安全性和隐私性的一些担忧。为此，我们提出了一种协议，通过该协议，参与急诊服务的所有治疗团队都可以安全地解密患者EMR中的相关数据，并添加有关患者状态的新信息。此外，我们的协议可确保治疗团队仅在患者护理期间访问患者的EMR。最后，我们对协议进行了正式的安全性分析，并提供了一些初步的实验结果。
