E-Commerce Authentication: An Effective Countermeasures Design Model.
Victor D. Sawma, Robert L. Probert · 2003
Abstract: Existing authentication models for e-commerce systems take into account satisfying legitimate user requirements described in security standards. Yet, the process of introducing countermeasures to block malicious user requirements is ad hoc and relies completely on the security designer expertise. This leads to expensive implementation life cycles if defects related to the design model were discovered during the system-testing phase. In this paper, we describe an authentication countermeasures design model for ecommerce systems. This model includes effective countermeasures against all known malicious user requirements and attacks. The described model is preventive in nature and can be used with other authentication models or can be implemented as a stand-alone module for e-commerce systems. 1
