Summary: | Wireless sensor networks are widely used in industrial process control, human health care, environmental
control, vehicular tracking and battlefield surveillance, etc. A wireless sensor network consists of lots of sensor nodes
and a gateway node. The sensor node usually communicates with the gateway node and users over an ad hoc wireless
network. However, due to the open environments, the wireless sensor networks are vulnerable to variety of security
threats. Thus, it is a critical issue to adopt a suitable authentication mechanism for wireless sensor networks to
enhance security. In 2009, Vaidya et al. proposed a robust user authentication schemes for wireless sensor networks.
In this article, we will show that their scheme is vulnerable to the guessing attack and the impersonation attack. Since
it needs a secure channel for communications in password changing phase, their scheme is also inconvenient and
expensive for users to update passwords. We also propose an improved scheme to remedy the flaws. The improved
scheme withstands the replay attack and off-line guessing attack, and the users can freely update their passwords via
public channels. |
