Criminal activity in the Internet is becoming more sophisticated. Traditional information security techniques hardly cope with recent trends. Honeypots proved to be a valuable source of threat intelligence. In this work several Honeypots are combined into a Honeynet and observed exploitation attempts. The Honeynet consists of six Honeypots and was operated for 222 days. 12 million exploitation attempts...
Research into the security of the Internet of things is increasingly attracting the attention of the scientific community. This study examines three key security requirements, with an emphasis on Internet systems of things: authentication, privacy and access control. Attention is focused on security issues that have not been resolved to date, and also addresses the problems and future trends in the...
Once a company is located on several sites, the communication between these sites would be critical for its activity, regardless of its size. VPN technology allows the connection between these different sites, while giving the user the benefit of the security. New Generation VPN technologies allow to create multiple virtual tunnels between various devices in a fast, automatic and dynamic manner. However,...
This paper presents a secure protocol for authenticating Electronic Control Units (ECUs) in the Controller Area Network (CAN) bus and establishing session keys between them. These keys are used to introduce message source authentication for the CAN network. Our method is based on the elliptic curve cryptography (ECC) which is more suitable for embedded systems where computational power and memory...
Due to massive advantages of short range communication technologies such as NFC and RFID, they are ubiquitously utilized in many fancy and sensitive applications. During last decade, there have been impressive endeavors to design efficient authentication protocols which can provide secure and anonymous communication for end-users. In this research, we formally analyze a recently improved authentication...
Recently, several protocols have been proposed to accomplish user authenticity with proper session key establishment in Global Mobility Network. Unfortunately, some of them still suffer from various security threats and high computational complexity. This article demonstrates a new enhanced two-factor authentication scheme for secure anonymous communication to mutually authenticate the communicating...
Many-core architectures are similar to a computer network, where it is necessary to ensure the security during the execution of sensitive applications. This article discusses two security-related issues: the secure admission of applications and the prevention of resource sharing during their execution. The safe application admission is an open research subject for many-core systems. Although several...
Electric vehicles are becoming parts of our daily lives with the increasing investment from auto industry. However, their charging is an issue as this requires frequent charging and longer waiting times compared to traditional gasoline-based vehicles. The charging is typically done at residential or public charging stations. With the increased dominance of electric vehicles, one potential solution...
In this paper, we investigate multi-message authentication to combat adversaries with infinite computational capacity. An authentication framework over a wiretap channel (W_1, W_2) is proposed to achieve information-theoretic security with the same key. The proposed framework bridges the two research areas in physical (PHY) layer security: secure transmission and message authentication. Specifically,...
In order to ensure that the message is fresh, both the identity of the communication and the shared key in the session are reliable, while avoiding the defects of the old message retransmission attack and identity posing in the native NS protocol, the optimized protocol adopts the means by which the receiver communicates with the key distribution center, and add the sender's identity and the temporary...
By applying power usage statistics from smart meters, users are able to save energy in their homes or control smart appliances via home automation systems. However, owing to security and privacy concerns, it is recommended that smart meters (SM) should not have direct communication with smart appliances. In this paper, we propose a design for a smart meter gateway (SMGW) associated with a two-phase...
Location-based queries have brought challenging privacy issues for mobile users. Having access to data, anytime from anywhere, raises many security concerns. One of these concerns is user's location privacy, where a user must reveal her location to get the desired result. The question is how to benefit from such queries without endangering user's location privacy. This paper presents a new method...
Often considered as the brain of an industrial process, Industrial control systems are presented as the vital part of today's critical infrastructure due to their crucial role in process control and monitoring. Any failure or error in the system will have a considerable damage. Their openness to the internet world raises the risk related to cyber-attacks. Therefore, it's necessary to consider cyber...
The IoT is a technology that enables the inter-connection of smart physical and virtual objects and provides advanced services. Objects or things are generally constrained devices which are limited by their energy, computing and storage capacity. A Wireless Sensor Networks (WSN) is a network composed of devices managed by a CPAN (Personal Area Network Coordinator). The network is used in order to...
Internet of Things (IoT) is slowly but steadily becoming part of different aspects of our lives, with its applications ranging from smart homes, to wearable devices, to healthcare, etc. This wide spectrum of applications results in shared data containing large amount of users' private information. The security of such information becomes a paramount concern. The IoT security requirements include data...
Radio frequency identification is a modern technology for item identification that has widely spread over the recent years. In order to securely identify the items and transfer their ownership from one entity to another, several authentication and ownership management protocols have been proposed. One of the recent protocols is Niu et al.'s EPC Class 1 Generation 2 RFID Standard Authentication and...
Wireless Sensor Networks (WSNs), deployed in distributed Internet of Things (IoT) applications, measure data, process, exchange information, and function collaboratively with other sensor nodes and end-users, which can be internal or external to the network. To maintain the reliable connectivity and the accessibility of distributed IoT, it is vital to establish secure links for end-to-end communication...
The Internet of Things(IoT) has been developing rapidly since the past decade. It is becoming a crucial part of everyday life. It is becoming a way of living in which machines perform activities on their own by communicating with each other, without the need for human beings to instruct them. In such a scenario, which concerns daily life, privacy, and secrecy should be of at most priority. Since in...
Mobile e-health is one of the Internet of Things application that assists the healthcare organization in providing better healthcare services. Development of wireless sensor networking area has greatly increased the feasibility of a mobile e-health system since it provides wireless communication technology with promising sensor network applications. However, mobile e-health is subjected to a lot of...
Despite the considerable benefits of cloud computing as an emerging technology, there are some reliability and privacy concerns such as generating and managing access policies according to sensitivity of stored data in cloud storages. The most challenging issue in current information policy models is managing security levels, mapping between access requests and defined policies and considering the...
