一个电子健康协议的形式化分析

Formal Analysis of an E-Health Protocol

Naipeng Dong, Hugo Jonker, Jun Pang

摘要:

鉴于健康数据的敏感性,电子保健系统的安全和隐私至关重要。至关重要的是,电子保健系统必须确保用户保持隐私-即使他们被贿赂或强迫透露自己或他人的信息:例如,制药公司可能贿赂药剂师透露侵犯医生隐私的信息。在本文中,我们首先确定和正式几个新的,但重要的隐私属性对执行医生的隐私。然后分析了一个复杂而实用的电子健康协议DLV 08的安全性和隐私性。我们的分析揭示了协议中的歧义,并显示在何种程度上这些新的隐私属性以及其他安全属性(如保密性和认证)和隐私属性(如匿名性和不可追溯性)的协议得到满足。最后,我们解决了发现的模糊性,导致安全和隐私缺陷,并提出了修复它们的建议。

英文摘要:

Given the sensitive nature of health data, security and privacy in e-health systems is of prime importance. It is crucial that an e-health system must ensure that users remain private - even if they are bribed or coerced to reveal themselves, or others: a pharmaceutical company could, for example, bribe a pharmacist to reveal information which breaks a doctor's privacy. In this paper, we first identify and formalise several new but important privacy properties on enforcing doctor privacy. Then we analyse the security and privacy of a complicated and practical e-health protocol (DLV08). Our analysis uncovers ambiguities in the protocol, and shows to what extent these new privacy properties as well as other security properties (such as secrecy and authentication) and privacy properties (such as anonymity and untraceability) are satisfied by the protocol. Finally, we address the found ambiguities which result in both security and privacy flaws, and propose suggestions for fixing them.
