En la societat actual, s'utilitza Internet diàriament per a dur a terme qualsevol tasca com consultar el correu electrònic o realitzar una transferència bancària. La majoria de serveis utilitzen noms per a ser identificats: els famosos dominis d'Internet. Els dominis s'han de convertir en un format numèric per ser utilitzats, una adreça IP. Aquest sistema de traducció s'anomena DNS. Actualment les consultes a servidors DNS s'envien en text clar, el que representa l'absència de privacitat i, per tant, són susceptibles per ser utilitzades per qualsevol que tingui interès. El propòsit d'aquest treball és analitzar la seguretat del sistema DNS i proposar una solució tecnològica a un problema de seguretat o privacitat existent. El resultat obtingut és una investigació sobre la seguretat i privacitat del protocol DNS i una proposta d¿un protocol de seguretat UDP Segur sense negociació en la capa de transport. The Internet is used daily nowadays to perform any task, for instance to check your email or to make a money transfer. Most services use names in order to be identified: the so-called Internet domains. These domains have to turn into numbers to be able to be used, an IP address. This translated system is called DNS. Currently, searches on DNS domains are performed as a clear text, which means lack of privacy so, as a result, anyone interested can use them. The purpose of this project is to analyse the security of the DNS system and suggest a technological solution to an existing security or privacy problem The result is an investigation about the security and the privacy of the DNS protocol and a proposal for a safe UDP security protocol without negotiation in the transport layer.
