Certificateless Remote Anonymous Authentication
Schemes for Wireless Body Area Networks
ABSTRACT:
Wireless body
area network (WBAN) has been recognized as 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 a 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 is 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 betweendesirable
security properties and computational overhead, nicely meeting the needs of
WBANs.
EXISTING SYSTEM:
In WBAN, where
biological information of concerns like heartbeat rate and blood pressure are
gathered by the sensors around the body (in-body networks) and transmitted to
body area network (BAN) controller nodes (out-body networks), such as PDA and
smart phones, which serve as a gateway for anonymously accessing the services
provided by external networks and servers.
DISADVANTAGES
OF EXISTING SYSTEM:
·
leakage
of privacy information due to WBAN's unique characteristics, such as open
medium channel, signal noise, mobile terminals, flexible infrastructure, and so
on.
PROPOSED SYSTEM:
Ø We develop a new CLS scheme as the cryptographic
primitive, which is cost-effective, efficient, and provably secure against
existential forgery on adaptively chosen message attack in the random oracle
model by assuming that CDHP is intractable.
Ø The proposed CLS scheme then serves as a design basis
for two remote anonymous authentication protocols, which are particularly
suitable for resource-constrained mobile clients. In particular, the protocols
use an anonymous account index instead of a WBAN client’s real identity to
access WBAN service, thereby preventing the potential privacy leakage to
application providers (APs) and network managers (NMs).
Ø A formal security analysis on our proposed protocols
is conducted, laying a theoretic foundation for examining the soundness and
performance of the similar designs.
