Preprint
Full-text available
Oblivious data processing has been an on and off topic for the last decade or so. It provides great opportunities for secure data management and processing, especially in the cloud. At the same time, modern computing resources seem to be affordable enough to allow for practical use of homomorphic cryptography. Yet, the availability of products that...
Conference Paper
Full-text available
ASEAN region is currently in a unique position from the perspective of air traffic management. It comprises a large amount of independent states with limited collaboration between air traffic regulators; large aquatic zones often make air travel the only viable option, creating high demand for denser air traffic; on the other hand, there is low vis...
Conference Paper
Full-text available
Unmanned air traffic management system (UTMS) and the ecosystem around it can be viewed as a large, complex, loosely-coupled cyber-physical system with flows of digital and analog data, sensors that collect data, and actuators that act upon data. As such, the ecosystem has a large cyber-attack surface, which, if penetrated, can cause serious damage...
Conference Paper
Full-text available
Unmanned aircraft are quickly gaining credibility as an efficient tool for a wide range of tasks. With the increase in the amount of UAVs in the sky, the need for the UAV traffic management arises. Unmanned air traffic management system (UTMS), especially in the urban airspace, could be considered as a critical infrastructure, which—if disrupted—ca...
Technical Report
Full-text available
Cyber security is a concern for any country's critical infrastructures, digital or physical. With the aspiration to valorize Singapore's controlled airspace by allowing unmanned aerial vehicles to engage in civilian and commercial activities, cyber security concerns must be extended to this new form of critical infrastructure. As UTM and UAS in an...
Thesis
Full-text available
Migration of data storage and processing appliances to the cloud is a stable trend in recent years. As many confirm, enterprises could gain various managerial and financial advantages from such change. However, at the same time, new security risks arise. In particular, certain risks of confidential data leaks. Using cloud platforms typically means...
Conference Paper
Full-text available
Oblivious data processing has a potential to make an extremely significant impact on the whole landscape of data processing, specifically in scenarios that could be classified as big data. Recent developments in the area of fully homomorphic cryptography make oblivious data processing much more realistic. However, performance implications could ren...
Conference Paper
Full-text available
Database-as-a-Service is offered by many cloud service providers and could significantly reduce the IT infrastructure maintenance bills for enterprises. However, many hesitate migrating their data storage and processing to the cloud, and one of the reasons are data security issues. Encryption could provide sound security guarantees, but existing ap...
Conference Paper
Full-text available
With high and growing supply of Database-as-a-Service solutions from cloud platform vendors, many enterprises still show moderate to low demand for them. Even though migration to a DaaS solution might result in a significantly reduced bill for IT maintenance, data security and privacy issues are among the reasons of low popularity of these services...
Conference Paper
Full-text available
Even though the concept of a Database-as-a-Service (DaaS) is becoming more popular and offers significant expenditure cuts, enterprises are still reluctant to migrate their data storing and processing to the cloud. One of the reasons to that is a lack of solid security guarantees. Encrypted database is one of the major approaches to address the sec...
Conference Paper
Full-text available
While DaaS is becoming more and more popular enterprises start considering it as an option to reduce IT maintenance costs. But data privacy and security issues keep most of them from moving to the cloud. Existing schemes of encrypting the database usually either provide a very basic search only (e.g., SELECT * FROM t WHERE t.a = 5) and nothing more...
