摘要: Widespread usage of mobile devices in conjunction with malicious software attacks calls for the development mobile-device-oriented mechanisms aiming to provide strong authentication and transaction security. This paper considers eBanking application scenario argues that concept using a trusted companion device can be ported realm. Trusted involve established proven techniques PC (personal computer) environment secure transactions. Various options communication between are discussed evaluated terms technical feasibility, usability, cost. Accordingly, audio across 3.5-mm jack--also known as tip-ring-ring-sleeve, or TRRS connector,--is determined quite appropriate. We present proof-of-concept implementing binary frequency shift keying this interface. Results from field study performed further confirm feasibility proposed solution.
