Recent initiatives known as Future Internet Architectures (FIAs) seek to redesign the Internet to improve performance, scalability, and security. However, some governments perceive Internet access as a threat to their political standing and engage in widespread network surveillance and censorship. In this paper, we provide an in-depth analysis of the design principles of prominent FIAs in terms of their packet structure, addressing and naming schemes, and routing protocols to foster discussion on how these new systems interact with censorship and surveillance apparatuses. Further, we assess the extent to which existing surveillance and censorship mechanisms can successfully target FIA users while discussing privacy enhancing technologies to counter these mechanisms. We conclude by providing guidelines for future research into novel FIA-based privacy-enhancing technologies, and recommendations to guide the evaluation of these technologies.

MIL-STD-1553 is a communication bus that has been used by many military avionics platforms, such as the F-15 and F-35 fighter jets, for almost 50 years. Recently, it has become clear that the lack of security on MIL-STD-1553 and the requirement for internet communication between planes has revealed numerous potential attack vectors for malicious parties. Prevention of these attacks by modernizing the MIL-STD-1553 is not practical due to the military applications and existing far-reaching installations of the bus. We present a software system that can simulate bus transmissions to create easy, replicable, and large datasets of MIL-STD-1553 communications. We also propose an intrusion detection system (IDS) that can identify anomalies and the precise type of attack using recurrent neural networks with a reinforcement learning true-skip data selection algorithm. Our IDS outperforms existing algorithms designed for MIL-STD-1553 in binary anomaly detection tasks while also performing attack classification and minimizing computational resource cost. Our simulator can generate more data with higher fidelity than existing methods and integrate attack scenarios with greater detail. Furthermore, the simulator and IDS can be combined to form a web-based attack-defense game.

Aerospace and defense industries are particularly vulnerable to cyber threats given their sensitive nature, significantly extending the consequences of security breaches to the national level. Aerospace vehicles are augmented by cooperative control, intelligent, connected, and autonomous systems. The risk against such systems is further amplified due to commonly relying on the MIL-STD-1553 communication bus developed with a high focus on reliability and fault tolerance, albeit with security as a second priority. MIL-STD-1553 (a.k.a., STANAG 3838 by NATO) is a standard that describes a serial data communication bus primarily used in aerospace vehicles for military and civilian applications, including avionics, aircraft, and spacecraft data handling. In the absence of core security measures such as authentication, authorization, and encryption, the bus connecting sensitive functions, including autopilot, GPS, fuel valve switches, and other avionics equipment, is easily vulnerable to a wide range of attacks. This paper proposes, AdaptIDS, a novel adaptive intrusion detection system as a security analytics framework for the MIL-STD-1553 communication bus. AdaptIDS mainly adopts data science principles and leverages advanced deep learning techniques (i.e., the stacking ensemble) to boost its generalization capabilities for detecting unseen patterns of attacks in the dynamic changing environment of aerospace vehicles. Extensive experiments are conducted using two datasets generated from an open-source simulation system, reflecting dynamic real-life scenarios. The evaluation results demonstrate that our solution outperforms existing solutions with high detection effectiveness of 0.99 F1-measure and computational time efficiency.
