Priya Mayank, Anil Kumar Singh · 2017
Today anonymity and privacy are the major concerns of Internet users. There are several types and implementations of anonymizing services available on the Internet. Tor is one of the services among those services. Tor networks are based on onion routing concept, and is now very popular. Surprisingly, very few research has been done on such an anonymizing network. Activist, journalist and writers use this tool for their freedom of speech, but it is also mis-used by malware, distributed denial of service attacks, hidden services that sells illegal things, spams, and many more. This paper will explain Tor usage detection by analysing the TLS connection that is used to make the connection secure and using the characteristics found during analysis to detect and block the Tor traffic originated from Tor browser.
