Lightweight Security for JXME-Proxied Relay Authentication

Mobile devices have become ubiquitous, allowing the integration of new information from a big range of objects. But the development of new applications requires a powerful framework which simplifies their construction. JXME is the JXTA protocols implementation for mobile devices using J2ME. The main value of JXME is its simplicity when creating peer-to-peer (P2P) applications on limited devices. However, providing a minimum security baseline to such applications is becoming a key issue, which is specially challenging when constrained devices are concerned. This paper proposes a simple security mechanisms in order to protect applications against a broad range of vulnerabilities. The protocol overhead has been experimentally tested in order to assess its low impact on device performance, an important requisite on limited devices.
