A Forgery Attack on A Low Computation Cost User Authentication Scheme.
Eun‐Jun Yoon, Kee-Young Yoo · International journal of network security · 2006
In 2005, Lee-Lin-Chang proposed a low computation cost user authentication scheme for mobile communication. However, the current paper demonstrates the vulnerability of Lee-Lin-Chang’s scheme to a forgery attack, where an attacker can easily masquerade other legal users to access the resources at a remote system and then presents an simple solution to isolate such a problem.
