Private instant messaging mooted.
BitTorrent, the company best known for the eponymous distributed file
sharing protocol, has intensified work on a decentralised
peer-to-peer chat app that aims to make it harder for government spy
agencies to snoop on users' communications.
The server-less chat client was announced in September this year.
Referring to NSA contractor Edward Snowden's revelations about mass
government surveillance of phone and Internet users, BitTorrent says
that events have since made it clear that the company needed to
devote time and resources to develop a messaging app that protects
privacy.
Unlike traditional instant messaging systems, BitTorrent Chat will
not use a central server for authentication of users as well as
routing and storing their communications. Under that model,
compromising the central server or eavesdropping on the
communications to and from it would leave all users of an instant
messaging service vulnerable to identification and interception.
Instead, BitTorrent Chat makes it possible for users to talk directly
to each other over an encrypted channel. By using an encrypted
distributed hash table (DHT), users' BitTorrent chat clients locate
others by querying neighbours for addresses, until the right peer is
found.
Only the person issuing the query knows the address in question,
BitTorrent says.
An invite-only alpha or early pre-release version of BitTorrent Chat
is currently being readied by the company along with a new open
sourced DHT bootstrap server for freshly installed clients that do
not yet have any peers to communicate with.
