摘要：
Password authentication schemes are used for networks to protect resources from unauthorized access. The ad hoc networks, due to dynamic nature and vulnerable-to-attack structure, require authentication mechanisms to ensure security. In 2007, Chai et al. proposed a threshold password authentication scheme that servers could efficiently obtain mutual authentication with users in ad hoc networks. However, their scheme suffers from insiders impersonate attack. In this article, we will propose an improved threshold password authentication scheme to fix the flaw. Our scheme is efficient to be implemented in mobile devices.
