Mobile Ad-hoc networks (MANETs) are the collection of two or more nodes can communicate with each other without the help of network infrastructures. Mobile nodes are free from moving any direction. Hence, there may be frequently link break happened. The difficult task in MANET is periodically maintains its routing information. Cross-Layer Design is suitable approach for providing QoS in MANETS, but traditional layered approach is designed for wired networks. It is difficult to provide QoS guarantee in ad-hoc networks with limited bandwidth and dynamic topology. But in Cross-Layer monitor is a logical entity to collect network state information like end-to-end throughput, application layer QoS requirements, latency, node throughput of link layer and remaining bandwidth in real-time applications. The main moto of this book is to learn to increase packet delivery ratio, reduce end-to-end delay in multimedia packet sharing.

Confidentiality is a major concern for cloud computing users who must ensure that their sensitive data is protected from unauthorized access or exposure, while still allowing for efficient sharing and collaboration among authorized parties. To address this challenge, a variety of encryption and access control techniques have been proposed and deployed, with varying levels of success.One promising approach to ensuring confidentiality in cloud computing is through the use of proxy re-encryption(PRE), which allows for the secure delegation of decryption rights from one party to another without compromising the privacy of the underlying data. PRE offers a number of advantages over traditional encryption techniques, including the ability to support fine-grained access control,efficient key management, and secure collaboration in multi-party environments.This book provides a comprehensive overview of PRE and its applications in cloud computing security. It covers the theoretical foundations of PRE, including its mathematical underpinnings and security properties, as well as practical aspects such as key management, performance optimization, and integration with other security mechanisms.

Studienarbeit aus dem Jahr 2022 im Fachbereich Informatik - Künstliche Intelligenz, Note: 1,3, Universität Hamburg, Veranstaltung: Komplexe Methoden qualitativer empirischer Untersuchungen, Sprache: Deutsch, Abstract: In einer Gegenüberstellung des Iconic und Pictorial Turns, die beide einen Paradigmenwechsel in den Bildwissenschaften beschreiben, wird sich dem Verhältnis von Bild und Sprache genähert. Am Beispiel einer Bildanalyse eines Artificial Intelligence-Bildes wird der Widerspruch zwischen Text als Befehl für die Erstellung eines AI-Bildes und den gleichzeitigen Eigensinn von Bildern herausgearbeitet.In der Auseinandersetzung mit dem Iconic und Pictorial Turn wird herausgearbeitet, welche theoretischen Annahmen von Boehm und Mitchell mithilfe der AI bestätigt oder hinterfragt werden können. Für dieses Vorhaben wurde eine Gliederung in insgesamt sieben Teilbereiche gewählt. Das erste inhaltliche Kapitel (2.) führt in die wissenschaftstheoretischen Erläuterungen des Iconic und Pictorial Turns (2.1. & 2.2.) ein. Die Kürze der vorliegenden Arbeit erlaubt keine allumfassende Darlegung der Überlegungen von Boehm und Mitchell. Es wird jedoch in der Kürze umrissen, welche Hauptargumente angebracht werden und zu welchem Schluss die beiden Theoretiker gelangen. Anschließend verschafft das Kapitel drei einen Überblick über die Definition von Artificial Intelligence und über die technischen sowie interaktiven Möglichkeiten, die sich durch DALL-E mini eröffnen. Es wird darauf hingewiesen, dass die Quellen dieses Kapitels aufgrund der Aktualität des Themas nicht wissenschaftlichen Charakters sind. Wie ein AI-generiertes Bild in der Interaktion entsteht und aussieht, wird in Kapitel vier dargestellt. An dieser Stelle wird auch eine kurze Bildbeschreibung vorgenommen, um der Eigenart eines AI-Bildes näher zu kommen.

This book presents Double Guard, an IDS system that models the network behavior of user sessions across both the front-end web server and the back-end database. By monitoring both web and subsequent database requests, it is possible to ferret out attacks that independent IDS would not be able to identify. Furthermore, it is possible to quantify the limitations of any multi-tier IDS in terms of training sessions and functionality coverage. This work implemented Double Guard using an Apache web server with MySQL and lightweight virtualization.
