Reducible Complexity in Dns
DNS is one of the most important components of the Internet infrastructure. Unfortunately, it is known to be difficult to implement, and available implementations are difficult to configure correctly. DNS performance and availability often suffer from poor configuration which leads to unavailability or erroneous behavior of distributed systems that depend on DNS. The data structures of DNS are ...
متن کاملDNS-sly: Avoiding Censorship through Network Complexity
We design DNS-sly, a counter-censorship system which enables a covert channel between a DNS client and server. To achieve covertness and deniability in the upstream direction, DNS-sly applies user personalization, adapting to individual behaviors. In the downstream direction, it utilizes CDN-related DNS responses to embed data, while retaining statistical covertness. We show DNS-sly achieves do...
متن کاملDNS Privacy
KURZFASSUNG Im Domain Name System (DNS) existieren sowohl auf Seiten der Clients als auch auf Seiten der Betreiber erhebliche Sicherheitslücken im Bezug auf die Vertraulichkeit und Privatheit der jeweils eigenen Daten. Der Informationsfluss von Clients, die einen Domain Name auflösen wollen, findet unverschlüsselt statt und wird meist durch mehrere Server geleitet. Serverbetreiber und Angreifer...
متن کاملRearchitecting DNS
The Domain Name System (DNS) has been the naming service of the Internet for more than 20 years. It is the foundation of virtually all other distributed service. The deficiencies of DNS with respect to performance, availability, and reliability are well known. We want to systematically improve DNS by (1) measuring DNS performance, (2) evaluating past proposals, and (3) try to come up with a new...
متن کاملA Demonstration of DNS: a Semantic-Aware DNS Service
The Domain Name System (DNS) is a hierarchical and distributed database used to resolve domain names into IP addresses. The current Web infrastructure heavily relies on the DNS service to allow endusers to access Web pages and Web data using meaningful names (like “www.verisign.com”) rather than cryptic sequences of numbers (e.g., “69.58.181.89”). The main functionalities of the DNS have been s...
