Cryptanalysis of Threshold Password Authentication Against Guessing Attacks in Ad Hoc Networks
Chun‐Ta Li, Yen‐Ping Chu · International journal of network security · 2009
Recently, Chai et al. proposed a threshold password authentication scheme that t out of n server nodes could efficiently carry out mutual authentication with a user while preserving strong security requirements in the mobile ad hoc networks. In this article, we will show that their scheme suffers from a number of security vulnerabilities by passive attacks.
