In conventional DNS, or Do53, requests and responses are sent in cleartext. Thus, DNS
recursive resolvers or any onpath adversaries can access privacy-sensitive information. To …

Recent advances in programmable switch hardware offer a fresh opportunity to protect user
privacy. This paper presents PINOT, a lightweight in-network anonymity solution that runs at …

Recently, a number of obfuscation systems have been developed to aid in censorship
circumvention scenarios where encrypted network traffic is filtered. In this paper, we present …

The Domain Name System (DNS) is used in every website visit and e-mail transmission, so
privacy is an obvious concern. In DNS, users ask recursive resolvers (or" recursives") to …

Abstract Network Address Translation (NAT) routers aggregate the flows of multiple devices
behind a single IP address. By doing so, NAT routers masquerade the original IP address …

Virtually every Internet communication typically involves a Domain Name System (DNS)
lookup for the destination server that the client wants to communicate with. Operators of DNS …

The Domain Name Service (DNS) is ubiquitous in today's Internet infrastructure. Almost
every connection to an Internet service is preceded by a DNS lookup. A vast majority of DNS …

Virtually every connection to an Internet service is preceded by a DNS lookup which is
performed without any traffic-level protection, thus enabling manipulation, redirection …

Tor is a powerful and important tool for providing anonymity and censorship resistance to
users around the world. Yet it is surprisingly difficult to deploy new services in Tor—it is …
