This article classifies common Internet banking authentication methods regarding potential threats and their level of security against common credential stealing and channel breaking attacks, respectively. The authors present two challenge/response Internet banking authentication solutions, one based on short-time passwords and one certificate-based, and relate them to the taxonomy above. There further outline how these solutions can be easily extended for nonrepudiation (that is, transaction signing), should more sophisticated content manipulation attacks become a real problem. Finally, they summarize their view on future requirements for secure Internet banking authentication and conclude by referencing real-live implementations.
Index Terms:
Internet banking, authentication, short-time passwords, short-lived passwords, public-key certificates, taxonomy of attacks
