摘要：Psiphon is a user-friendly stand-alone proxy application designed to securely circumvent Internet censorship. It is specifically intended for people living in countries where there is Internet content filtering who have friends or relatives living in countries where there is not. Unlike other circumvention technologies, Psiphon relies on multiple social networks of trust, rather than mass publication of IPs or proxies, which can be easily intercepted and filtered by a determined state.
Unlike other proxy applications, Psiphon does not require installation of a web server or any other programs.
