Il-Gon Kim, Hyunseok Kim, Ji‐Yeon Lee, Jin‐Young Choi · 2006
Generally, security protocols have been designed and verified using informal techniques. In the result, it is now well recognized that many security protocols which were previously proposed have found to be vulnerable later on. In this paper, we model and verify of the ASK protocol, which is a complicated mobile security protocol. After showing the vulnerability of the ASK protocol using formal verification approach, we propose a modification, and then show that the new protocol is secure against replay attack
