A security infrastructure for massive mobile data distribution

Abstract

Many modern mobile applications have to address the challenge of enabling communication and managing a very large amount of mobile nodes. Examples of those applications include fleet management, workforce coordination, Intelligent Transportation Systems, cooperative mobile robots, rescue and emergency management, and environmental surveillance. Data distribution is an essential part of those systems, and the data traffic often contains sensitive information - thus enforcing the need of the CIA triad (confidentiality, integrity and availability). This work presents a data distribution layer based on the OMG DDS standard, developed to enforce CIA for data distribution through the usage of PKI and symmetric cryptography. This layer provides all required PKI-related functionality and symmetric key management, offering mobile devices an affordable data distribution solution.
