Secure AIS with Identity-Based Authentication and Encryption

The Automatic Identification System (AIS) offers automatic traffic control and collision avoidance services to the maritime transportation sector worldwide. Because AIS lacks security mechanisms, it is vulnerable to misuse and exploitation by unlawful adversaries (e.g. sea-pirates, terrorists, smugglers). To address the security issues of the AIS, in an earlier paper [1], we proposed the deployment of a Maritime Certificate-less Identity-Based (mIBC) public-key cryptography infrastructure that enhances AIS with on-demand anonymity, authentication, and encryption capabilities. In this paper we address implementation aspects of that infrastructure. In particular, we propose to use the Sakai-Kasahara Identity-Based Encryption (IBE) approach to implement the mIBC infrastructure, following the IEEE 1363.3-2013 standard for Identity-Based Cryptography.
