The objective of the PKA encryption scheme is to complement, or replace, existing Public Key Infrastructures (PKI) [1]. In this scheme, the initialization step is based on the secure exchange of addressable cryptographic tables between the communicating parties. These tables are generated either with random numbers, or with arrays of addressable Physical Unclonable Function (PUFs). The subsequent...
Home Automation Systems have been continuously evolving in the past few years: some of the systems are focusing their attention on providing remote access and control of the system, while others are more focused on the interconnectivity of the devices and on integrating them into greater systems, like smart cities. In this paper we propose a hierarchical architecture for Home Automation Systems, which...
Remote access Trojans (RATs) are used by attackers to compromise and control the victim machine. In this work, a novel Network-based framework is introduced for detecting RAT bots based on data mining techniques. Several machine learning (ML) techniques are used to differentiate between benign and RAT infected machines. Various performance measurements are used to evaluate the performance of the proposed...
The paper proposes the solution of the actual scientific problem of load balancing and efficient use of distributed system resources. The proposed method is based on the calculation of the load of the central processor, memory and bandwidth fractal information streams of different classes of service for each server and the entire distributed system. The method allows calculating the imbalance of all...
In accordance with the resent advancement in Internet of Things (IoT), the needs for IoT experiment platform have been ever increasing. IoT system consists of various technologies such as networking, sensor controller, edge-side computing, server-side big data collections, analysis and their visualizations. An experimental environment that can handle the development and experiments of such an IoT...
Since computing infrastructure has intrinsically a redundant logic, budget saving practices or understaffing of IT departments lead to an “emergency room” service paradigm. However, a treasure of information that could facilitate preemptive maintenance is buried in the logs and messages that are automatically generated by regular processes. Such information is typically ignored because of the shear...
In recent years, many organizations, companies and government agencies have been suffering from brutality of targeted attacks. Especially, destructive targeted attacks such as Shamoon and Samas have been causing significant damages on the targets' cyber assets, disputing their critical business operations. Since such attacks tend to access many hosts simultaneously, a rapid incident response is essential...
It is well known that load balancing and low delivery communication cost are two critical issues in mapping requests to servers in Content Delivery Networks (CDNs). However, the trade-off between these two performance metrics has not been yet quantitatively investigated in designing efficient request mapping schemes. In this work, we formalize this trade-off through a stochastic optimization problem...
Named Data Networking (NDN) is a promising Future Internet architecture to support efficient content distribution. Specifically, P2P may gain benefits from NDN, as NDN inherently provides a flexible forwarding plane for multi-source and multi-path communications. Existing studies in this area have proposed solutions, but these are adversely affected by link latency. This leads to illogical resource...
To address the challenges raised by the Internet usage evolution over the last years, the Content-Centric Networking (CCN) has been proposed. One key feature provided by CCN to improve the efficiency of content delivery is the in-network caching, which has major impact on the system performance. In order to improve caching effectiveness in such systems, studying the functioning of CCN in-network storage...
Remote server vulnerability exploit is one of the most troublesome threat to the Internet security. An effective defense against the remote vulnerability exploit is code randomization, which randomizes the program code address to disrupt the malicious payload execution. Unfortunately, code randomization is particularly susceptible to address exposure vulnerabilities; the leak of a single code or data...
Data outsourcing has become quite popular in recent years. While the rapid development of cloud storage service, it brings about many new security challenges. One of the biggest concerns with cloud data storage is that of data integrity at untrusted cloud servers. For example, when individual users store important data files in cloud servers, the data files may be damaged or corrupted because of cloud...
Combining data analytics with homomorphic encryption is an interesting topic, which finds several applications in the healthcare domain because it enables clients with low computational and/or storage capacity to outsource the analysis of potentially large datasets to the cloud while protecting sensitive data from unwanted access. In this work, we propose a framework for evaluating k-means clustering...
Middleboxes (MBs) are ubiquitous in modern data centre (DC) due to their crucial role in implementing network security, management and optimisation. In order to meet network policy's requirement on correct traversal of an ordered sequence of MBs, network administrators rely on static policy based routing or VLAN stitching to steer traffic flows. However, dynamic virtual server migration in virtual...
Cloud storage is a service provided by cloud service provider (CSP). More and more individuals and organizations accept the scheme and outsource their data to CSP seeking to reduce local storage burden. Since the outsourced files are no longer under the data owners' direct control and CSP is not trustworthy, it is necessary for data owners to check the integrity of their files outsourced to CSP. To...
We have proposed a distributed storage system which dynamically makes storage tiers and optimizes location of data blocks autonomously. This aims to enhance the I/O performance of the storage system without remarkable network overhead. Our system dynamically organizes storage tiers considering device characteristics. And the data blocks will be placed in a suitable storage tier according to their...
Stateful programmable dataplanes are emerging as a disruptive technology and an enabler factor for network function virtualization in SDN environments. In this demo paper we show three real world use cases with stateful forwarding requirements to validate both the hardware and software implementations of the Open Packet Processor data plane.
Current network switches cannot be programmed and flexibly controlled. Then, developers of a data center application system, which is composed of software and computers connected with a network, are not able to optimize behavior of network switches on which the application is running. On the other hand, Deeply Programmable Network (DPN) switches can completely analyze packet payloads and be profoundly...
Nowadays high performance computers (HPC) are used to solve increasingly complex problems and process larger amounts of data. The growing computational requirements of applications can be met by utilizing more compute nodes. However, the average I/O performance a compute node can utilize is reduced with increased number of nodes. The performance gap between computation and I/O has long been a primary...
High Performance Computing (HPC) facilities serve as infrastructure for solving demanding computational problems met in various domains. HPC involves expensive resources both material and operational. Therefore, leveraging its operation at his peak capacity is very important from economic efficiency perspective. Nowadays, it is very difficult for a regular researcher that needs HPC services to have...
