Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - The current textbook is about the security in mobile ad-hoc networks by using cryptographic secrete key. Now-a-days security is a major challenging problem in mobile ad-hoc networks because the nodes in mobile ad-hoc networks are moving from one place to another due to this the structure of the network changes frequently. The topology changes may cause 'routing modification attack' problem that can easily be exploited against the MANETs. The main goal of routing attacks is to disrupt normal functioning of network by advertising false routing updates. On the other hand data communication attacks include modification or dropping of data packet that does not disrupt routing protocol. In this work, this could be achieved by adding some extensions for secure routing. These extensions include integrity which means the message modification is not allowed and authentication which means the node validation (identification) is done. This protection is provided by a hashed message authentication code function that provides fast message verification and information about sender as well as intermediate node authentication.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The old ink and paper method of a biometric system is at risk to a variety of attacks. These attacks are intended to either avoid the security afforded by the system or to put off the normal functioning of the system. The old ink and paper method which is grossly susceptible to wear and tear makes it very vulnerable. Proper use of cryptography hash functions greatly reduces the risks in automated biometric systems as hackers have to find both secret key and template. It is evidenced that still fraud goes on to some extent. Here in this paper a new idea is presented to make system more secure by use of encryption and its HMAC code. Here the secret key (which is in the form of pixel intensities) will be merged in the picture itself while encoding and its unique corresponding HMAC code generated, and at decoding end only the authentic user will be allowed to decode and digitally encrypted hashed image is stored in the database for future references and usages. 204 pp. Englisch.

Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - El presente libro de texto trata de la seguridad en las redes móviles ad-hoc mediante el uso de claves secretas criptográficas. Hoy en día, la seguridad es un problema importante en las redes móviles ad-hoc porque los nodos de las redes móviles ad-hoc se desplazan de un lugar a otro, por lo que la estructura de la red cambia con frecuencia. Los cambios de topología pueden provocar un problema de 'ataque de modificación de enrutamiento' que puede explotarse fácilmente contra las MANET. El objetivo principal de los ataques de enrutamiento es interrumpir el funcionamiento normal de la red anunciando falsas actualizaciones de enrutamiento. Por otro lado, los ataques a la comunicación de datos incluyen la modificación o la caída de paquetes de datos que no interrumpen el protocolo de enrutamiento. En este trabajo, esto podría lograrse añadiendo algunas extensiones para un enrutamiento seguro. Estas extensiones incluyen la integridad, que significa que no se permite la modificación del mensaje, y la autenticación, que significa que se realiza la validación del nodo (identificación). Esta protección se proporciona mediante una función de código de autenticación de mensajes con hash que proporciona una rápida verificación de los mensajes e información sobre el remitente, así como la autenticación del nodo intermedio.El presente libro de texto trata de la seguridad en las redes móviles ad-hoc mediante el uso de claves secretas criptográficas.
