Internet was designed for network services without any intention for secure communication. Exponential growth of internet and its users have developed an era of global competition and rivalry. Denial of service attack by multiple nodes is capable of disturbing the services of rival servers. The attack can be for multiple reasons e. g. extortion or to beat the rivals. Peer

This paper discusses the concept of a virtual digital forensic laboratory, which incorporates networked examination and storage machines, secure communications, multi-factor authentication, role-based access control, and case management and digital asset management systems. Laboratory activities such as the examination, storage and presentation of digital evidence can be geographically distributed and accessed over a network by users with the appropriate credentials. The advantages of such a facility include reduced costs through shared resources and the availability of advanced expertise for specialized cases.

Presently, mobile handheld device has successfully replaced traditional telephone to become the most popular wireless communication tools. Mobile Short Message Service (SMS) and Multimedia Message Service (MMS) fulfill almost all the user requirements as an effective communication and information delivering service. Since SMS/MMS become so popular on daily communication, there is a demand to communicate or exchange confidential information in a secure environment. Public Key Infrastructure (PKI) is a proven solution, which using pairing of key, for secure communication encryption. In this paper, m–PKI is introduced to provide PKI encryption to the mobile SMS and MMS. This new approach allows the end-user to send private and classified message via SMS. The key pair generation and distribution are performed by the Certificate Authority (CA). The size of the key pair are studied and decided by the tradeoff between performance and security.

Auf den letzten Seiten ihrer Studie Political Community and the North Atlantic Area (1969) geben die Autoren um Karl W. Deutsch ihrer Hoffnung Ausdruck, die NATO werde in Zukunft mehr sein als ein rein militärisches Bündnis. Über die wechselseitige politische und militärische Unterstützung hinaus sollten die Mitgliedsländer zu einer nordatlantischen politischen Gemeinschaft heranwachsen, auf deren Gebiet Konflikte und Kriege aufgrund gemeinsamer Erfahrungen, Werte und Erwartungen zunehmend unwahrscheinlich werden. Dieser Transformationsprozess beruhe weniger auf den militärischen Kapazitäten des Verteidigungsbündnisses als vielmehr auf der Entwicklung einer „gesellschaftlichen Gemeinschaft“ (Talcott Parsons). „This indicates that opportunities to integrate the North Atlantic area do not necessarily depend upon the continuation of a Soviet military threat, although that threat does seem to have helped toward greater unity“ (Deutsch u.a. 1957: 202).

Two-way identity authentication is the basis of secure communication in a distributed application environment. A trusted third party (TTP) is needed while PKI is not applicable, and the design of authentication protocols with TTP is a complicate and challenging task. This paper examines the characteristics of the security of authentication protocols with TTP, summarizes the essential factors of session key

Security has become paramount in modern software services as more and more security breaches emerge, impacting final users and organizations alike. Trends like the Microservice Architecture bring new security challenges related to communication, system design, development, and operation. The literature presents a plethora of security-related solutions for microservices-based systems, but the spread of information difficult practitioners' adoption of novel security related solutions. In this study, we aim to present a catalogue and discussion of security solutions based on algorithms, protocols, standards, or implementations; supporting principles or characteristics of information security, considering the three possible states of data, according to the McCumber Cube. Our research follows a Systematic Literature Review, synthesizing the results with a meta-aggregation process. We identified a total of 30 primary studies, yielding 75 security solutions for the communication of microservices.

It has been recently investigated that the jerk dynamical systems are the simplest ever systems, which possess variety of dynamical behaviors including chaotic motion. Interestingly, the jerk dynamical systems also describe various phenomena in physics and engineering such as electrical circuits, mechanical oscillators, laser physics, solar wind driven magnetosphere ionosphere (WINDMI) model, damped harmonic oscillator driven by nonlinear memory term, biological systems etc. In many practical situations chaos is undesirable phenomenon, which may lead to irregular operations in physical systems. Thus from a practical point of view, one would like to convert chaotic solutions into periodic limit cycle or fixed point solutions. On the other hand, there has been growing interest to use chaos profitably by synchronizing chaotic systems due to its potential applications in secure communication. In this paper, we have made a thorough investigation of synchronization of identical chaotic jerk dynamical systems by implementing three well-known techniques: (i) Pecora-Carroll (PC) technique, (ii) Feedback (FB) technique and (iii) Active Passive decomposition (APD). We have given a detailed review of these techniques followed by the results of our investigations of identical synchronization of chaos in jerk dynamical systems. The stability of identical synchronization in all the aforesaid methods has also been discussed through the transversal stability analysis. Our extensive numerical calculation results reveal that in PC and FB techniques the x-drive configuration is able to produce the stable identical synchronization in all the chaotic jerk dynamical systems considered by us (except for a few cases), however y-drive and z-drive configurations do not lead to the stable identical synchronization. For the APD approach, we have suggested a generalized active passive decomposition, which leads to the stable identical synchronization without being bothered about the specific form of the jerk dynamical system. Several other active passive decompositions have also been listed with their corresponding conditional Lyapunov exponents to achieve the stable identical synchronization in various chaotic jerk dynamical systems.

There is a need to quantify system properties methodically. Dependability and security models have evolved nearly independently. Therefore, it is crucial to develop a classification of dependability and security models which can meet the requirement of professionals in both fault-tolerant computing and security community. In this paper, we present a new classification of dependability and security models. First we present

South America’s security agenda demands the simultaneous management of domestic crises, interstate conflicts and transnational threats. Though located at different systemic levels (national, international, transnational), the three conflict clusters are often interrelated and tend to overlap in the region’s border areas. The region’s policy makers, aware of this highly complex agenda and in spite of their striking differences, have tended

Visible Light Communication (VLC) is a blooming research area which uses visible light spectrum as the communication channel. Exponential growth of Light Emitting Diodes (LEDs) deployment as a light source is encouraged to use for communication purposes as well. With the introduction of VLC, LED can be used for communication while providing the primary function of illumination. Since location-based network access protocols have not been implemented for Wi-Fi devices, this research has been conducted with the intention of using VLC to perform location-based authentication. In our location authentication protocol, VLC technology is used for authentication purpose and Wi-Fi is used for data transfer once the device has been authenticated. The proposed protocol provides location-based connectivity to Wi-Fi devices with minimum changes to Remote Authentication Dial-In User Service (RADIUS) and Wi-Fi Protected Access 2 (WPA2) protocol by using VLC.
