CERTIFICATELESS REMOTE ANONYMOUS AUTHENTICATION SCHEMES FOR WIRELESS BODY AREA NETWORKS
Wireless body area network (WBAN) has been recognizedas one of the promising wireless sensor technologies for improving healthcare service thanks to its capability of seamlessly and continuously exchanging medical information in real time. However, the lack of an clear in-depth defense line in such a new networking paradigm would make its potential users worry about the leakage of their private information, especially to those unauthenticated or even malicious adversaries. In this paper, we present a pair of efficient and light-weight authentication protocols to enable remote WBAN users to anonymously enjoy healthcare service. In particular, our authentication protocols are rooted with a novel certificateless signature (CLS) scheme, which is computational efficient and provably secure against existential forgery on adaptively chosen message attack in the random oracle model. Also, our designs ensure that application or service providers have no privilege to disclose the real identities of users. Even the network manager, which serves as private key generator in the authentication protocols, is prevented from impersonating legitimate users. The performance of our designs are evaluated through both theoretic analysis and experimental simulations, and the comparative studies demonstrate that they outperform the existing schemes in terms of better trade-off between desirable security properties and computational overhead, nicely meeting the needs of WBANs.
By using wireless personal area network (WPAN) technologies for communications on, near and around the human body, T. G. Zimmerman firstly proposed Wireless body area network (WBAN) in 1996. The work then immediately drew much attention from both academia and industry. For instance, IEEE802.15 has developed a family of short distance communication standards. In particular, 802.15.6 was formally standardized in 2012 after five years effort of engineers from sixty companies. It is about the low power wireless sensor nodes used in WBAN to gather biomedical information for various applications in hospitals, residential and work environments. Basically there are two categories of WBAN applications, i.e., medical and non-medical ones. Medical applications need to collect vital information of a patient continuously and forward it to a remote monitoring station for further analysis. This huge amount of data can be used to prevent the occurrence of myocardial infarction and treat various diseases such as gastrointestinal tract, cancer, asthma, and neurological disorder. Non-medical applications include monitoring forgotten things data file transfer, gaming, and social networking applications.
DISADVANTAGES OF EXISTING SYSTEM:
vHuge amount of data to be stored.
vOnly session massage with non-negligible probability.
