Information security is a concern in integrated electronic health record systems (EHRs). This paper discusses the development of a mathematical model to secure the access of EHRs. In this paper, we incorporate the notion of a broadcast encryption scheme for securing EHRs. We present a novel solution to allow a secure access to the EHRs whilst minimising the number of the encrypted ciphertexts. In a nutshell, our proposed solution enjoys shorter ciphertexts compared to having multiple ciphertexts encrypted for several different participants. Our proposed solution is applicable in practice to solve an existing open problem in the effort of securing EHRs.
信息安全是集成电子健康记录系统（EHRs）中的一个关注点。本文讨论了一种用于保障电子健康记录访问安全的数学模型的开发。在本文中，我们纳入了用于保障电子健康记录安全的广播加密方案的概念。我们提出了一种新颖的解决方案，以实现对电子健康记录的安全访问，同时尽量减少加密密文的数量。简而言之，与为多个不同参与者加密多个密文相比，我们提出的解决方案的密文更短。我们提出的解决方案在实际中适用于解决保障电子健康记录安全方面现有的一个开放性问题。
