| 摘要： | As an important part of Internet of Things (IoTs),body area networks (BAN) have been developed for providing medical diagnostics. A large number of wearable or embedded body sensors are used to sense and collect patient’s personal physiological information and transmit it to the backend of the medical systems for healthcare monitoring. However, due to its
openness, protecting sensitive data from unauthorized access is a vital issue in medical-related system. Recently, Deng et al.
proposed a secure and lightweight network admission and communication scheme based on Internet of Things for body area network healthcare system. However, after a detailed
inspection of their scheme, we found Deng et al.’s scheme is not secure enough as they claimed and then demonstrated that their
scheme is vulnerable to various attacks, such as data replaying attack and user traceability attack. To eliminate the vulnerabilities of Deng et al.’s scheme, in this paper, we proposed an enhanced network admission and communication scheme for IoT-based body area network healthcare system while also providing mutual authentication, data confidentiality
and data integrity. |
