摘要

移动健康护理作为一种新兴的技术给个人健康档案的分享提供了极大的便利，也给其隐私带来了极大的风险。基于属性的加密体制能够对加密数据实现细粒度的访问控制，有效地保护了个人健康档案的隐私。然而，目前基于属性的访问控制方案要么缺乏有效的恶意用户追踪机制，要么只支持单个授权机构。针对该问题，提出了一个移动健康护理环境下适应性安全的可追踪多授权机构基于属性的访问控制方案，该方案在合数群上构造，支持任意单调的线性秘密共享机制的访问策略，基于子群判定假设证明了该方案在标准模型下是适应性安全的，基于k-SDH假设证明了该方案的可追踪性，性能分析表明了该方案的实用性。

Abstract

Mobile healthcare (mHealth) is an emerging technology which facilitates the share of personal health records (PHR)

however

it also brings the risk of the security and privacy of PHR.Attribute-based encryption (ABE) is regarded as a new cryptology to enhance fine-grained access control over encrypted data.However

existing attribute-based mHealth systems either lack of efficient traceable approach

or support only single authority.A traceable multi-authority attribute-based access control mHealth scheme was proposed

which was constructed over composite order groups and supports any monotonic access structures described by linear secret sharing scheme (LSSS).The adaptive security was proved under subgroup decisional assumptions.The traceability was proved under k-strong Diffie-Hellman (k-SDH) assumption.The performance analysis indicates that the proposed scheme is efficient and available.
