Abstract

With the increasing popularity of security and privacy sensitive systems on mobile devices, such as mobile banking, mobile credit cards, mobile ticketing, or mobile digital identities, challenges for the protection of personal and security sensitive data of these use cases emerged. A common approach for the protection of sensitive data is to use additional hardware such as smart cards or secure elements. The communication between such dedicated hardware and back-end management systems uses strong cryptography. However, the data transfer between applications on the mobile device and so-called applets on the dedicated hardware is often either unencrypted (and interceptable by malicious software) or encrypted with static keys stored in applications. To address this issue we present a solution for fine-grained secure application-to-applet communication based on Secure Remote Password (SRP-6a), an authenticated key agreement protocol, with a user-provided password at run-time. By exploiting the Java Card cryptographic API and minor adaptations to the protocol, which do not affect the security, we were able to implement this scheme on Java Cards with reasonable computation time.
