Special Issue Information

Dear Colleagues,

Internet of Things (IoT) and mobile networks are two of the key technologies that simultaneously advance the industry progress and boom the potential growth of economics. With the integration of the two technology areas, the communications not only reach much wider areas, but also boom new applications and business opportunities; however, it also incurs more security threats and the infected potentials of the connected systems.

IoT technologies have been widely applied in agriculture areas, vehicles, factories, communications, transportation, armies, critical intra-structures, etc. The advancement of mobile systems (such as 4G, 5G, 6G, Starlink, etc.) cover much wider areas and the transmissions are much more efficient. However, the integration of these systems involves more diversities in technologies and in devices. Some of them are powerful systems with some enforced protections while others being weaker components with obvious vulnerabilities. To enhance the security protection of the system and deter possible threats, it needs diverse security mechanisms and the orchestration of the various security mechanisms. Therefore, this Special Issue aims at inviting all security solutions that could tackle some security issues in the integrated systems.

Some security mechanisms and topics are listed as follows. IoT authentication, intrusion detection, machine learning, block chains, mobile system infra-structures and integration, inverse engineering, Over-the-Air activation, etc.

In this regard, we need both the specific security solutions for each specific application/sub-system and the integration/framework that federate the various security functions.

Original contributions, not currently under review to another journal or conference, are solicited for this Special Issue. We hope to attract a diverse group of researchers, academics, designers, and others to discuss these issues from a broad range of perspectives. Potential topics include, but are not limited to:

  • Mobile systems with security and privacy considerations;
  • IoT systems with security and privacy considerations;
  • Big data analytics tools and techniques in mobile systems/5G/IoT security;
  • Big data analytics for mobile systems/5G/IoT security;
  • Lightweight cryptographic algorithms and protocols;
  • Wireless virtualization and slicing security;
  • Authentication, authorization, and accounting (AAA) for mobile system security;
  • Secure integration of IoT/mobile systems/5G;
  • Security and privacy in cloud/fog/edge computing;
  • Secure device-to-device communications;
  • Over-the-Air activation;
  • Intrusion detection/prevention techniques for mobile systems/5G/IoT;
  • Cross-layer/cross-domain/cross-service security in mobile systems/5G/IoT;
  • Blockchain-based service and applications for mobile systems/5G/IoT;
  • Secure data storage, communications, and computing;
  • Heterogeneous system modeling for 5G security;
  • Secure sensing and computing techniques in 5G;
  • Machine learning applied in IoT systems or mobile systems;
  • Trust models and trust handling for federating 5G-IoT security.

It is common to implement challenge-response entity authentication with a MAC function. In such an entity authentication scheme, aggregate MAC is effective when a server needs to authenticate many entities. Aggregate MAC aggregates multiple tags (responses to a challenge) generated by entities into one short aggregate tag so that the entities can be authenticated simultaneously regarding only the aggregate tag. Then, all associated entities are valid if the pair of a challenge and the aggregate tag is valid. However, a drawback of this approach is that invalid entities cannot be identified when they exist. To resolve the drawback, we propose group-testing aggregate entity authentication by incorporating group testing into entity authentication using aggregate MAC. We first formalize the security requirements and present a generic construction. Then, we reduce the security of the generic construction to that of aggregate MAC and group testing. We also enhance the generic construction to instantiate a secure scheme from a simple and practical but weaker aggregate MAC scheme. Finally, we show some results on performance evaluation.

Over-the-air (OTA) updating is a critical mechanism for secure internet of things (IoT) systems for remotely updating the firmware (or keys) of IoT devices. Message queue telemetry transport (MQTT) is a very popular internet of things (IoT) communication protocol globally. Therefore, MQTT also becomes popular in facilitating the OTA mechanism in many IoT platforms, such as the Amazon IoT platform. In these IoT platforms, the MQTT broker acts as the message broker and as an OTA server simultaneously; in these broker-based OTA architectures, it is quite common that an IoT application manager not only uploads the new firmware/software to the broker but also delegates his signing authority on the firmware/software to the same broker. If the broker is secure and trusted, this OTA model works well; however, it incurs lots of security concerns if the broker is not fully trusted or if it is curious. Many MQTT deployments do not own their own brokers, but rely on a third-party broker, which sometimes is a freeware program or is maintained by a curious third party. Therefore, a secure OTA process should protect privacy against these brokers. This paper designs a novel MQTT-based OTA model in which an IoT application manager can fully control the OTA process through an end-to-end (E2E) channel. We design the model using MQTT 5.0’s new features and functions. The analysis shows that the new model greatly enhances security and privacy properties while maintaining high efficiency. Full article
