    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.…

TOTP - Time-basedOne-time Password Algorithm is an extension of the HMAC-based One TimePassword algorithm HOTP to support time based moving factor. TOTP waspublished as an Information IETF RFC in May 2009 (Draft 03). it is acornerstone of Initiative For Open Authentication (OATH).TOTP can beused to authenticate a user in a system via an authentication server.Also, if some more steps are carried out, the user can also authenticatethe validation server. The TOTP draft was developed through thecollaboration of several OATH members in order to create anindustry-backed standard. It complements the event-based one-timestandard HOTP, and offers end user organizations and enterprises morechoice in selecting technologies that best fit their applicationrequirements and security guidelines. In addition, OATH also submittedthe final version of the OCRA (OATH Challenge-Response Algorithms)specification to the IETF. This version incorporates all the feedbackand commentary that the authors received from the technical communitybased on the prior versions submitted to the IETF.…

HOTP is anHMAC-based One Time Password algorithm. It is a cornerstone ofInitiative For Open Authentication (OATH). HOTP was published as anInformation IETF RFC 4226 in December 2005, documenting the algorithmalong with a Java implementation. Since then, the algorithms was adoptedby many companies worldwide and became the world's leading standard forevent-based OTP authentication. The HOTP algorithm is a freely availableopen standard.…

    Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - L'attuale libro di testo riguarda la sicurezza nelle reti mobili ad-hoc utilizzando la chiave segreta crittografica. Oggigiorno la sicurezza è un problema importante nelle reti ad-hoc mobili perché i nodi nelle reti ad-hoc mobili si spostano da un posto all'altro a causa di questo la struttura della rete cambia frequentemente. I cambiamenti di topologia possono causare un problema di 'attacco di modifica del routing' che può essere facilmente sfruttato contro le MANET. L'obiettivo principale degli attacchi di routing è quello di interrompere il normale funzionamento della rete pubblicizzando falsi aggiornamenti di routing. D'altra parte gli attacchi alla comunicazione dei dati includono la modifica o l'abbandono di pacchetti di dati che non interrompono il protocollo di routing. In questo lavoro, questo potrebbe essere ottenuto aggiungendo alcune estensioni per il routing sicuro. Queste estensioni includono l'integrità che significa che la modifica del messaggio non è consentita e l'autenticazione che significa che la convalida del nodo (identificazione) è fatta. Questa protezione è fornita da una funzione hashed message authentication code che fornisce una verifica veloce del messaggio e informazioni sul mittente così come l'autenticazione del nodo intermedio.L'attuale libro di testo riguarda la sicurezza nelle reti mobili ad-hoc utilizzando la chiave segreta crittografica.

    Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - O livro de texto atual é sobre a segurança em redes ad-hoc móveis usando chave criptográfica de segredo. A segurança now-a-days é um grande desafio nas redes ad-hoc móveis porque os nós nas redes ad-hoc móveis estão se movendo de um lugar para outro devido a isso a estrutura da rede muda frequentemente. As mudanças na topologia podem causar problemas de 'ataque de modificação de rotas' que podem ser facilmente explorados contra os MANETs. O principal objetivo dos ataques de roteamento é interromper o funcionamento normal da rede através da publicidade de falsas atualizações de roteamento. Por outro lado, os ataques de comunicação de dados incluem modificações ou descargas de pacotes de dados que não interrompem o protocolo de roteamento. Neste trabalho, isto poderia ser alcançado adicionando algumas extensões para o roteamento seguro. Essas extensões incluem integridade, o que significa que a modificação da mensagem não é permitida e autenticação, o que significa que a validação do nó (identificação) é feita. Esta proteção é fornecida por uma função de código de autenticação de mensagem em hash que fornece verificação rápida da mensagem e informações sobre o remetente, bem como a autenticação do nó intermediário.O livro de texto atual é sobre a segurança em redes ad-hoc móveis usando chave criptográfica de segredo.
